1. My Best Overall Pick: Saatva Classic

Saatva classic mattress

The Saatva Classic luxury innerspring mattress is one of the highest rated mattresses sold online – period.

This luxury innerspring mattress has five layers designed to provide back support, contouring, motion control and cooling. Their unique coil-on-coil system ensures the mattress provides outstanding support and will last a long time without sagging or losing support.

Covering the top of the Saatva Classic is an organic cotton cover which feels super-soft and helps keep the surface of the mattress cool and fresh.

Right beneath it is a cushy Euro pillow top layer that gives the Saatva Classic a luxurious feel.

Before you get to the first coil layer, there is another thin layer of memory foam and polyfoam that enhances lumbar support and ensures you don’t feel the coils digging into your body.

The first coil layer consists of pocketed coils. Because they are individually wrapped, they contour your body better and eliminate pressure points.

Beneath the pocketed coils lies a base layer of tempered steel coils that prevents the mattress from sagging over time and ensures it will last long while still providing great support.

Dense foam encases the perimeter to reinforce edge support, which is great for couples who tend to sleep near the edges.

The Saatva Classic mattress comes in three comfort levels: Plush Soft, Luxury Firm (most popular) and Firm.

You can also choose between an 11.5” thick version or the more luxurious-looking 14.5” thick mattress.

They currently offer free white glove delivery as well as free mattress removal if you need it.

This is a good thing, because innerspring mattresses like the Saatva Classic are quite heavy, and you may not be able to set one up yourself. With most other mattresses, you have to pay extra for the mattress to be brought into your bedroom and set up on your foundation or box spring.

Saatva gives their customers a 180-day trial period with free returns and a 15-year non-prorated warranty.

2. Best Eco-Friendly Innerspring Mattress: Keetsa Pillow Plus

Best Innerspring Mattress

If you prefer buying organic or eco-friendly products, the Keetsa Pillow Plus is a great choice for an innerspring mattress.

NOTE: This mattress is not 100% organic – it does, however, use 100% eco-friendly materials that are safe for their customers as well as the environment.

It’s surprisingly affordable for an eco-friendly mattress, too. While most organic mattresses cost thousands of dollars, a Keetsa Pillow Plus queen goes for just $990.

The Pillow Plus is constructed of two main layers: a comfort section on top made of foam and a support layer made of coils.

The cover is 100% organic cotton and quilted with a natural fiber filling to create more airflow and improve cooling.

Beneath the cover is a plush pillow top layer that immediately relieves pressure when you lie on the mattress.

Below the pillow top is a layer of eco-friendly memory foam that provides support and contouring.

Keetsa calls their memory foam BioFoam.BioFoam

Unlike traditional memory foam which is made entirely of synthetic materials, the company has replaced some of the synthetic components with plant-based materials.

This reduces off-gassing and makes the mattress more eco-friendly.

Below the memory foam are three additional foam layers: double layers of responsive comfort foam and a support layer of high-density foam.

At the base, independent coils that Keetsa calls iCoils provide body contouring and boost overall support.

The Pillow Plus mattress is only available in one comfort level – medium firm.

Shipping is free within the contiguous United States as well as some areas in Canada. But they don’t offer help with setup, even for a fee.

The trial period is 90 days. Returns cost 10% of purchase price (one of the few online mattress companies that charge for returns).

Their warranty runs for 12 years and is non-prorated.

3. Best Overall Value: DreamCloud

DreamCloud Mattress Review

13”+ luxury innerspring mattresses like the DreamCloud typically cost $3,000+ for a Queen in stores.  The 14″ DreamCloud queen costs less than $1,000.

Yet it really doesn’t compromise anything to get to such an affordable price point.

If anything, I think the DreamCloud is more comfortable than almost any pricier mattress I've slept on in my life.  We like ours so much that we keep it in our guest room – and we've had nothing but compliments from our guests.

This mattress doesn't skimp on a thing. The DreamCloud is constructed using a sophisticated 5-layer system that provides one of the best sleeping experiences I've had on a bed-in-a-box.

At the very top is a luxury EuroTop quilted cover made of foam and cashmere.

The topmost layers include a mix of foams designed to provide support and pressure relief: 

  1. A gel-infused memory foam layer to improve cooling and contouring.
  2. A soft conventional foam layer for support.

Below the foam layers lies a thick bed of pocketed coils. This layer provides deep body contouring and compression support, especially for heavier folks.

Another layer of firm conventional foam rounds out the mattress construction at the base, improving overall support.

The DreamCloud mattress offers only one firmness choice: medium-firm.

Some customers (including us) think it's a bit on the firm side despite the pillow top.  But it's a far nicer sleeping experience than a foam mattress of the same comfort level.

Returns are free. If you decide to keep it, then you’ll be covered by DreamCloud’s lifetime Warranty.

Shipping is free for the continental US. They offer the option of paying extra for white glove delivery and old mattress removal.

4. Best Budget Innerspring Mattress: Amore

Best Innerspring Mattress

Innerspring mattresses tend to be pricey, with many topping $2,000 for a queen.

It’s unusual to see a premium innerspring mattress going for the price an Amore Bed goes for.

This mattress contains all the bells and whistles of a premium innerspring mattress – plus a few unique features – and a queen costs less than $1,000.

At 12” thick, the Amore mattress is a nice size. It looks great on your bed.

The Amore mattress is constructed of 6 layers consisting of specialized foam that is infused with unique materials to make the mattress more comfortable.

On top of the mattress is the organic cotton cover which is super soft and breathable. You can also opt for their copper ion-infused cover ($50 extra).

The copper-infused cover does feel slightly cooler. You’ll also benefit from the therapeutic and anti-microbial properties of the copper ions.

Under the cover, the Amore mattress adds an organic wool blend layer for cooling and chemical-free fire resistance.

The next four layers consist of different types of foam, each serving a specific role:

  1. A 1” gel-infused FusionFlexTM memory foam layer at the top is for cooling and contouring.
  2. A 1” layer of memory foam infused with graphite to improve heat dissipation.
  3. A 2” transition foam layer distributes your weight evenly across the mattress and prevents you from sinking in too much.
  4. a layer of high-density open-cell foam for added support and ventilation.

Below the foam layers, a bed of pocketed edge-to-edge coils provides contouring as you shift and turn at night. The coils also provide robust support especially along the edges where most mattresses tend to collapse.

A foundation layer of high-density foam complements the support from the coil layer and ensures longevity.

Amore lets you choose from a soft, medium or firm mattress when ordering. You can also get a custom split firmness option for $100 extra.

Shipping is free within the contiguous US.

The mattress comes with a 100-night trial period (with free returns) and a 20-year non-prorated warranty.

5. Best Custom Innerspring Mattress: Helix

Helix-Lifestyle-3-3330 (2)

Everyone has very particular preferences when it comes to the kind of mattress they want.

Some people like to feel like they are sleeping on a cloud, others prefer a firmer experience. Many fall somewhere in between.

The Helix mattress tries to meet everyone’s needs by offering a custom-designed mattress option.

Instead of offering a universal medium-firm mattress or giving you three firmness options to choose from, they will design your mattress specifically to meet your needs.

To do this, they ask you to answer a few questions before you order a mattress. Their online questionnaire asks about your sleeping preferences, sleeping position, height, and weight. You can also answer as a couple to get a blended or split mattress to meet both of your needs.

Every Helix mattress is constructed using three main components: Helix Dynamic foam, poly foam and pocketed coils.

Helix Dynamic foam is Helix's proprietary blend that combines the contouring and pressure relief of memory foam with the responsiveness of latex foam.

There are two poly foam layers below that: one is a transition between the top layer and coil layer and the other is the base. They provide support and ensure the mattress lasts a long time.

The core of the Helix mattress consists of pocketed coils that provide contouring, enhance compression support and give the mattress a nice bounce.

The individual wrapping around the coils improves airflow to help keep the mattress cool.

Shipping for the Helix mattress is free.

Once delivered, you have 100 nights to test it out and decide whether you want to return it (returns are free).

Their non-prorated warranty covers your mattress for 10 years.

In addition to their custom-designed mattress, Helix offers 9 mattresses designed for every type of sleeper and need – including their new Helix Nightfall which is designed for plus-sized sleepers.

6. Best Luxury Hybrid: Leesa Hybrid (Sapira)

Leesa Hybrid (Sapira) is a hybrid mattress made by Leesa, one of the best known online mattress brands.

This is a luxury innerspring mattress that costs the same as a mid range mattress.

The Leesa Hybrid (Sapira) mattress is built with three layers that work together to deliver a great sleeping experience.

The top layer is made of Leesa's proprietary foam, a special type of foam that is also found in the all-foam Leesa mattress.

Leesa's proprietary foam feels a bit like latex foam. It is responsive (bouncy) and feels cool. This makes your nights more comfortable (no heating and sweating), and makes it easier to move about in the bed than with a pure memory foam mattress.

To counter the slight firmness of the top layer, there is a memory foam layer underneath that also helps with contouring and pressure relief.

Finally, there is a core layer of pocketed steel springs sandwiched between two thin layers of foam.

The spring layer enhances contouring, prevents your partner from waking you up at night when they turn and keeps the mattress cool.

Shipping is free to every state in the US.

You can opt to pay an extra $99 to get the mattress set up for you plus another $50 to have your old mattress taken away for disposal.

The trial period runs for 100 nights (with free returns), and the non-prorated warranty covers your mattress for 10 years.

7. Best Innerspring Mattress for Plus-Sized People: Big Fig

Big Fig Mattress

If you are plus-sized, you really need a mattress that has excellent support first and foremost. Most mattresses won’t properly hold your weight, which can cause poor spine alignment and lead to back problems.  Or, you will “bottom-out” and feel the springs pressing into you.

The Big Fig mattress is designed to support more weight than usual without sagging or compromising support. It’s also made to last.

If you’ve had to go through several mattresses in just a few years, I recommend this one. It will likely last well over a decade.

Because heavier sleepers tend to have overheating issues, the Big Fig mattress makes use of several cooling techniques.

The first is in the quilted cover.   It is made from a blend of polyurethane, viscose and poly/lycra. It’s soft, tough and breathable and contains Thermogel, a type of cooling gel integrated into the fabric to improve heat dissipation.

The first layer of the mattress consists of gel-infused perforated latex foam. Because it is latex, it’s naturally cool. The perforated design and gel infusion are just extra bonuses to make sure it stays cool no matter the weather.

Below the latex foam lie three layers of high-density poly foam to provide no-sag support. Together with the latex layer, they make up the comfort section of the mattress.

The core of the mattress consists of up to 1600 high-grade pocketed coils that can hold up more weight than most other innerspring mattresses. They ensure the mattress stays flat and supportive after years of use and help with ventilation and contouring.

High-density foam is also added along the edges to shore up edge support, ensuring you get good support no matter where you sleep or sit.

Included in the purchase price is a specially crafted foundation designed to support you and the extra weight of the heavy duty mattress.

Big Fig offers free shipping in the US. You can opt to pay $99 to get help with setup or $159 for setup plus old mattress removal.

They offer a 101-night trial period with free returns and an outstanding non-prorated 20-year warranty.

8. Best Innerspring Mattress for Side Sleepers: Purple Hybrid Premier (4” Purple Grid)

luxury innerspring mattress

Side sleepers need an innerspring mattress with a thicker and plusher comfort section on top. This ensures the mattress sufficiently cushions your shoulder, ribcage and hip, and that you don’t feel the springs underneath.

The Purple Hybrid Premier has a 4” comfort layer on top of the innerspring core. The comfort layer is made from Purple’s exclusive hyper-elastic gel grid, a rubbery material with grids that provide targeted support and pressure relief.

Note that Purple Hybrid Premier mattress is available in two options; one with a 3” grid and another with a 4” grid.

We recommend the 4-incher because it contours better to your curves and cushion your pressure points more effectively. It feels like the hug of memory foam but without the mushy and hot feel that some people don’t like in memory foam mattresses.

The entire mattress is 12.5” thick. There’s a 1” layer of transition foam under the Purple Grid and a 7.5” base of pocket coils that provide deep contouring and support.

The Purple Hybrid Premier sleeps cooler than other foam hybrid mattresses. The elastic top layer doesn’t trap heat and the grids improve airflow at the surface of the mattress.

Shipping for the Purple Hybrid Premier mattress is free and you get 100 nights to test the mattress at home. Returns are free.

If you keep the mattress, the warranty runs for 10 years.

Note that the Purple Hybrid Premier mattress is pricey. It costs more than any other hybrid mattress in this buying guide. Curranty, a Queen size goes for $3,000.

But we think it’s worth it. And as a bonus, Purple is currently giving away free sheets and pillows with every mattress purchase.

9. Best Flippable Innerspring Mattress: Idle Hybrid

best firm innerspring mattress

Modern flippable mattresses combine two comfort options in one mattress. With the Idle Hybrid mattress, you can switch from medium to firm simply by flipping the mattress over.

This not only reduces the chances of returning the mattress because it is too soft or too firm; it also allows the mattress to keep up with your changing comfort needs.

If for instance you get a hip injury, you can switch from the firm side to the pressure-relieving medium side instead of buying a new mattress or topper.

The two sides have the same foam layers and share a pocket coil core. The first layer is 1” of soft IDLE contouring foam that provides instant pressure relief.

A 2″ layer of IDLE Cooling Buoyancy Foam provides additional body contouring and some responsiveness.

Finally, there’s a 1” transition foam layer before you get to the innerspring core.

Flip the mattress over and you get the same layout. The only difference is that one side has a medium feel that’s ideal for side sleepers and back sleepers weighing under 200lbs, while the other side has a luxury firm feel that’s suitable for stomach sleepers and heavier back sleepers.

The mattress is wrapped in a Thermocool™ fabric that maintains a constant range of temperature on the surface of the mattress. You stay warm when it’s cold and cool when it’s hot.

Idle offers free shipping plus a generous 18-month trial period with free returns. If you keep the mattress, you enjoy a lifetime warranty.

10. Best Organic Innerspring Mattress: Avocado Green

best organic innerspring mattress

The Avocado Green mattress combines organic latex, cotton and wool with a supportive layer of pocket coils.

Apart from the coils, everything else in the Avocado Green mattress is certified organic.

At the top is a GOTS certified organic cotton cover that keeps the surface of the mattress cool and breathable. Below it is GOTS certified organic wool that provides temperature control, moisture wicking and fire protection (wool is a natural fire retardant).

The Avocado Green mattress is available in two comfort options: standard and pillow top.

The Standard Avocado Green has two layers of GOLS certified organic Dunlop latex. A soft 2” layer on top and a firmer 1” layer in the base.

The Pillow Top Avocado Green has three layers of organic Dunlop latex. The same two layers as the standard mattress plus a plush 2” layer in the pillow top.

Both options have a pocket coil base with five support zones that target different areas of your body.

The standard Avocado Green has a medium-firm feel that’s great for stomach and back sleepers. It’s also the best option for people with back pain.

The pillow top Avocado Green has a soft feel that’s great for side sleepers and anyone who loves a luxuriously plush mattress.

Whichever option you pick, you’ll get a 1-year sleep trial at home with free returns.

The prorated warranty runs for 25 years.

Benefits and Drawbacks of an Innerspring mattress


  • Good support: Innerspring mattresses rank up there with latex mattresses when it comes to support. The coils hold up your weight much better than foam on its own. This has three benefits: you sleep comfortably without back problems, couples and heavier folks get the right amount of support and the mattress lasts longer without sagging.
  • Responsiveness: If you don’t like the mushy, dead feel of foam mattresses, you’ll love the responsiveness of innerspring mattresses. The bounciness makes these mattresses great for sex and people who constantly change their sleeping position.
  • Cool: The coil layer greatly increases ventilation/airflow within the mattress, which carries away heat. Innerspring mattresses are great for hot sleepers especially when paired with a breathable cover like cotton.
  • Good pressure relief: Just because it contains coils, it doesn’t mean that an innerspring mattress will leave your hips, shoulders and other pressure points aching. Many innerspring mattresses today have a thick layer of foam on top that provides excellent pressure-point relief.


  • Expensive: If you are shopping for a budget mattress, you’ll have better luck with a foam mattress. Innerspring mattresses cost more, with many starting at around $1,200 for a Queen size. A luxury innerspring mattress with a thick foam layer or a pillow top can cost over $2,000.
  • Heavy: The combination of metal coils and thick foam layers makes innerspring mattresses heavy and cumbersome. You may need to pay extra for help with set up or have a couple of other people around to help you carry it inside and set it up.
  • Some motion transfer: Because of the added bounciness, couples may find that they can feel some of their partner’s movements. This can be an issue if you are a light sleeper who is woken up by any slight disturbance. But most people don’t experience this problem with modern innerspring mattresses. The thick layers of foam on top and individually pocketed coils dampens most of the disturbance from your partner’s side of the bed.

How Much Do Innerspring Mattresses Cost?

Many start at around $1,200 for a Queen size. Prices can go up to $2,000 for innerspring mattresses with organic latex or a pillow top.

You can get cheaper innerspring mattresses for under $1,000 but these typically have thinner foam layers and may not be as comfortable.

How Are Innerspring Mattresses Different From Other Types Of Mattresses?

Innerspring mattresses contain a layer of coils that provides support, cooling, durability, and responsiveness. Two layers or more of foam or latex on top of the coils provide pressure-relief, body contouring, and motion isolation.

In contrast, foam mattresses contain only foam.

Who Should Buy an Innerspring Mattress?

I recommend an innerspring mattress to sleepers who…

Want a more traditional feel

Best Hybrid Mattress

Before latex and memory foam mattresses became, popular innerspring mattresses were the automatic choice for most people looking to buy a new mattress.

Even with many more choices today, a lot of people still love the slightly firm and bouncy feel of a traditional innerspring mattress.

Want a great bounce

Not even a latex mattress has the bounce of an innerspring mattress.

The extra bounce of a spring mattress is not just pleasurable; it also makes it easier to move about on the mattress and get out of bed. You don’t feel like you are stuck in the mattress.

It also makes spring mattresses great for sex.

Want a cool mattress

Spring mattresses stay cooler than all-foam mattresses. This is because of improved ventilation.

All those spaces in between the coils or springs allow air to flow in and out of the mattress. This ensures excess heat, smells and moisture are quickly dissipated out of the mattress.

Want a more durable bed

If you've owned an innerspring mattress before, you know that it lasts for years without showing any wear.

Modern innerspring mattresses are no different. If you want to know just how long they last, look at the warranties.

Many innerspring mattresses sold online today offer a 15 or 20-year non-prorated warranty with some going up to 25 years. Some of the newest brands are even offering a lifetime warranty.

Weigh more than average

Big Fig Mattress

Innerspring mattresses are the best for bigger-bodied sleepers. They provide more support and are far more durable than foam mattresses.

Qualities Of A Good Innerspring Mattress

Here are the most important features of a quality innerspring mattress.

Quality Springs

Sapira Mattress Review - pocket coil springs

Just because it is an innerspring mattress  doesn’t mean it is high quality.

An excellent innerspring mattress will have high-quality springs that can fully support your weight and are designed to last long.

Pocketed coil mattresses are the best type to buy these days. They offer better support and contouring and tend to last longer than other types of inner springs.

Comfortable Foam Layer for Pressure Relief

Saatva mattress review - CUTAWAY - BY CONSUMER REPORTS

One of the things you need to watch out for when buying an innerspring mattress is the firmness. Some tend to be a bit too firm for your comfort.

The best innerspring mattresses will usually have a comfort foam layer on top that is almost as thick or thicker than the core spring layer.

The comfort section usually contains 2 or 3 different types of foam such as memory foam, polyfoam, and latex foam.

A thick foam padding over the coils ensures the mattress feels comfortable especially around pressure points like your shoulders and hips.

Good Back Support

Best Innerspring Mattress

This is not a problem for most innerspring mattresses, as long as you choose the right firmness level.

Medium firm innerspring mattresses are ideal for most people. They provide a good balance between firm back support and soft contouring.

If you are on the lighter side of the scale or you are a side sleeper, opt for a softer mattress with extra contouring. For heavier sleepers, firmer and thicker mattresses provide better support.

Quality Materials

Best Cooling Mattress Pads

Like any other mattress, an innerspring mattress should have quality materials starting with the cover.

Organic cotton covers are very common now. They feel comfortable and are excellent at cooling and moisture-wicking. Polyester covers are good too.

Some premium innerspring mattresses go an extra mile and use a quilted cover that is more luxurious and lasts longer. Some mattresses will also be tufted, a technique that prevents the inner materials from shifting over time.

Make sure the foam is of good quality as well.

I highly recommend buying an American-made innerspring mattress because they are far more likely to use foams that are not only more comfortable and durable but also healthier.

Check for CertiPUR-US certification, at least. It means that the mattress is manufactured to high standards and doesn’t contain harmful chemicals.

Long Warranty

A good indicator of a mattress’s longevity is the warranty.

For all-foam mattresses, ten years is about right.

For innerspring mattresses, the ideal warranty period is 15-25 years.

How To Buy An Innerspring Mattress Online

Here are the most important factors to consider when buying an innerspring mattress online including coil type, coil gauge, and trial period.

Types of Coils

1. Pocket Coils

Helix mattress review - micro coils

These are the most common coils today. Some manufacturers may also refer to them as wrapped, encased, or Marshall coils.

The coils are shaped like a barrel or cylinder with each coil encased in its own fabric. So each coil reacts to motion and pressure independently from the other coils.

This has several advantages:

  • Better contouring. The mattress molds around your body for pressure relief.
  • Better motion control. Coils don’t transmit disturbances to each other. This is great for couples because they won’t wake each other up when they turn or get out of bed.
  • Improved ventilation and cooling. Air flows easily in between the coils, dissipating excess heat and moisture away from the mattress.

2. Bonnell Coils

The oldest types of coils but quickly falling out of favor in modern innerspring mattresses.

They consist of hourglass-shaped springs connected to each other with wires.

They are fairly good at contouring and are popular in orthopedic mattresses. But they tend to sag quickly, forming a dip in the middle of the mattress. They also transmit more motion across the mattress compared to pocket coil mattresses.

Today, you are more likely to find Bonnell coils in low-budget innerspring mattresses.

3. Offset Coils

These are very similar to Bonnell coils but with a flat square head (instead of around one). Individual coils are hinged to each other with helical wires.

Offset coils are great at contouring and can take a greater weight load than Bonnell coils. But because they are connected, they have more motion transfer.

4. Continuous Coils

Mattress Thickness vs Sleep Quality

This design consists of rows of coils consisting of a single piece of wire. The coils are then hinged with helical wires.

The main downside with continuous coil mattresses is the noise they make as you move about on the mattress. They also don’t contour as well to your body as other types of coils.

But they offer great support and can last long without sagging.

Note that this list is not comprehensive. Different brands may have their own proprietary coil designs. Sealy for instance, has ReST coils, SRx coils, and PostureTech coils.

Coil Count

Generally, the higher the coil count, the more supportive and long-lasting the mattress will be.

The number of coils will vary with mattress size. But don’t buy anything with less than 300 coils.

Coil Gauge

‘Gauge’ is a measure of how thick something is, in this case, mattress coils. ‘Low gauge’ means thicker while ‘high gauge’ means thinner.

Mattresses with high-gauge coils feel softer and have more sinkage because the wires are thinner. They are great for contouring.

Mattresses with low-gauge coils are firmer and have better support for couples and heavier sleepers.

If you want a softer mattress, look for mattresses with a coil gauge of at least 14. If you prefer something firmer, it should be no more than 13.

Unfortunately, most sellers don’t state what gauge their mattress is. They’ll simply say soft, medium-firm, or firm. So you just have to trust their assessment.

Type of Foam

Don’t just look at the coils; also consider the foam part of the mattress.

As I mentioned, most mattresses use 2 or 3 types of foam. The most common types of foam used are memory foam, polyfoam, and latex foam.

Some mattresses use proprietary foam such as Leesa's proprietary foam.

If you want a plush sleeping surface with excellent pressure relief, look for an innerspring mattress with memory foam.

If you want the mattress to be a bit firmer, look for latex or polyfoam.

White-Glove Delivery

DreamCloud Mattress Review - on forklift

Innerspring mattresses are heavy. Even two people are going to struggle to get it inside and set it up.

Most sellers offer setup and old mattress removal services either free or for an extra fee. They will take the mattress inside, unbox it and set it up on your foundation.

In-Home Trial

The standard trial period for online mattresses is 100 days, but some brands offer up to a whole year of home testing.

100 days is long enough to know whether a mattress is comfortable. But if you want to see how quickly it wears or how it feels in different types of weather get one that offers a year-long trial period.

Don’t forget to check that returns are free.

Why Buy An Innerspring Mattress Online?

  • Save money! In-store mattresses can cost twice or triple the price of online mattresses.
  • Convenience. You get more time to try it out at home, and returns are usually free.
  • Choice. You have many more choices online, and you can do better research on each of them. This ensures you buy the best mattress for your needs.

Frequently Asked Questions

Yes, as long as you choose a good quality one with a nice thick layer of foam on top. Factors like foam padding, coil gauge, and coil count will determine how comfortable the mattress will be.

Do you need a box spring with an innerspring mattress?

Not necessarily. You can use different types of foundations with an innerspring mattress.

If you choose a box spring, then most manufacturers recommend using a box spring designed specifically for spring mattresses.

You can also use a slatted frame, but make sure it can properly support the mattress especially in the middle (it should have center legs).

Are innerspring mattresses good for back pain?

Yes, they are. Firm support from the coils balances the soft pressure relief of the foam layers. This cushions your back from the pressure and ensures your spine is properly aligned.

But it’s important to choose the right firmness. Stomach sleepers with back pain need a firmer innerspring mattress for alignment. Back sleepers need a medium-firm mattress (or firm if you weigh over 230lbs) and side sleepers need a soft or medium comfort mattress.
