Unboxing and Setup

The Alexander comes compressed in a box, but unlike other mattresses-in-a-box, it is not folded in order to retain its integrity.

Once out of the box, it quickly expands to its normal size.

For setting up the bed, the Alexander does not come with a boxspring. But honestly you don’t need one. Any of the following options will work:

  1. a platform bed, which you can purchase from Nest
  2. an existing rigid foundation
  3. an adjustable base. Nest sells a few high-end options on their site.

Nest Alexander Signature Select mattress review - full bed on platform

The stylish design of the Alexander Signature Series mattress is revealed once you unpack it from its rather nondescript box.

The quilted cover is the most eye-catching part of the mattress. It has a beautiful classic style that shouts comfort. The top fabric has a nice floral pattern.

On the sides, the mattress has a more modern look, consisting of mesh and suede.

Overall, you get the feeling this is a very high quality product.  There is a serious attention to detail.

The type and placement of foam in a mattress is fundamental to how it functions and how long it lasts.

The Alexander Signature uses a unique combination of latex and gel foam layers to create the right mattress for each kind of sleeper.

Here are the three main firmness varieties on the Alexander Signature Series.

Alexander Soft Mattress

Nest Alexander Signature Select mattress review - cutaway view

The soft Alexander Select is topped with a 1.5″ quilted super-soft foam cover for premium sleeping comfort.

Beneath that is a 2-inch layer of 4-pound convoluted Gel Cooling memory foam over another 2-inch layer of 4-pound Visco foam.

Underneath that is a 3″ layer of SmartFlow Air Flow Foam, a Nest exclusive material that is exceptionally breathable.

The 4″ poly support base comes last.

The Alexander soft is really, really soft according to the company and most reviewers online. Only get the Soft if you are 100% certain a soft mattress works for you.

If you are especially light-framed or bony, or sleep 100% on your side, then an extra-soft mattress like this can help eliminate pain / pressure points.

Alexander Signature Series – Medium

The medium-firm Alexander is topped with a 2″ thick version of the same quilted cover as the Soft Alexander mattress.

Beneath the topper, the medium-firm mattress has a 4-inch layer of 4-pound convoluted Gel Cooling foam, the same material as used in the Soft version.

Below this, however, the medium-firm mattress adds 1 inch of 4-pound Visco foam and 2″ of SmartFlow Air Flow foam.

At the bottom is the 4″ support poly foam layer.

The Alexander medium is a good choice for side- and back-sleepers or people who regularly alternate positions, like me. Honestly, the vast majority of people should be happy with this one.

Alexander Signature Series – Luxury Firm

Nest Alexander Signature Select mattress review - LUXURY FIRM cutaway view

The firm Alexander Signature Series Luxury Firm mattress is a 4-layer design that’s topped with a 1.5-inch quilted cover; but, unlike the other two comfort levels, it lacks the super soft foam.

Below the cover is a 2-inch layer of 4-pound convoluted Gel Cooling foam over 3 inches of a firmer 4-pound version of the SmartFlow Air Flow Foam.

Under everything is a 6″ poly support base.

The Alexander Firm is the best choice for heavy people and for people who sleep on their stomach. It’s also the right choice for people who prefer Japanese-style flat beds & futons.

All latex used in the Alexander mattresses is Oeko Tex Certified while the foams are all CertiPUR certified. This ensures their safety.

Nest Alexander Signature Select mattress review - quilted topper

Nest really did a great job on the cover of the Alexander Signature Series. It smacks of premium quality.

Once you have gotten past the beautiful floral handiwork on the quilted fabric, you have to lie down on the mattress to experience just how soft the cover is.

Beneath the top fabric, there is a layer of super soft foam (soft and medium only).

Another important role played by a mattress cover is heat dissipation. I found the Alexander Signature Series excellent at dissipating heat in my New Orleans home. I tested it in the early Fall, which is pretty dang hot and humid down here.

Nest Bedding does not offer alternative materials or designs other than the ones described here.

Smell/Off Gassing

Nest Bedding insists that their mattresses lack any chemical smell.

True to form, I experienced zero new mattress smell once I unpacked the Alexander. It was first-night smell free, which is really unusual for an online foam mattress.

Some mattresses also experience what is referred to as off-gassing (also called outgassing). For foam mattresses, this occurs when VOCs or volatile organic compounds are emitted from foam materials.

Though the Alexander Signature Series is technically not an organic mattress, it nevertheless undergoes extensive safety checks and measures to ensure its safety.

Because all foam used in the Alexander is CertiPUR certified and the latex is Oeko Tex certified, you can be sure that no off gassing will occur throughout the life of the product.

According to Nest, there are no VOCs, (volatile organic compounds) emitted by the foams used in the Alexander. The US Environment Protection Agency (EPA) says that VOCs can cause various health problems, including cancer.

Sleeping Experience

Nest Alexander Signature Select mattress review - sleeping experience

The sleeping experience is of course the most important feature of any mattress.

Alexander’s predecessor, the Love Bed is a great mattress with perhaps one or two drawbacks.

According to many reviews online, both the medium and the firm were a bit too firm, while the soft was a bit lacking when it came to support.

The Alexander seems to have corrected these problems, except perhaps for the soft one.

I tested the Alexander medium. I have to say, it achieves that delicate balance between firmness and softness.

While you will certainly feel the super soft cover, the foam below holds firm. I experienced a mattress that is really comfy but firm enough to give me a great feeling of support.  No pain points noted (I sleep on my back and side, mainly).

From other reviews online, the Alexander soft appears to be really soft.  If you love the feeling of sinking in and getting a super soft bed embrace, then this is the choice for you.

Another important part of the sleeping experience is the cooling. I found that my body heat was transferred away from the surface of the mattress. Most nights I remained cool and comfy.

↑ Table of Contents


Nest Alexander Hybrid Signature Select - comfort level

To get an idea of just how firm or soft each mattress is, I am going to rate them on a scale of 1–10, with 1 being the firmest and 10 the softest.

My husband and I only tested the Alexander medium.

Due to the cover, the Alexander medium is softer than most other mattresses of comparable firmness. It is even softer than the Love Bed (4/10). It gets a 6/10 rating.

Based solely on other people’s reports, I’ll give the Alexander firm a 2/10. This is a step better than the Love Bed firm (1/10), which I and many others thought was just way too firm.

I did not test the Alexander soft, either. But Nest gives it a “very soft” 8.5/10 rating.  They warn on their site, “Please do not order the soft unless you like a VERY soft mattress!”

Nest Alexander Signature Select mattress review - sinkage test

Sinkage refers to how much the mattress sinks under various conditions. The sinkage of a mattress is an important part of the overall sleeping experience. If it sinks too much, you feel as if you are stuck in mud.

In my testing, I found the Alexander Select medium definitely has more sinkage than comparable medium firm mattresses such as Casper and Bear. This is probably due to the soft quilted/foam cover topper they use.

That said, I did not find the sinkage really inhibited my movement in any way. It’s nothing like that awful “body impression” issue you have to fight with cheap memory foam mattresses.

↑ Table of Contents

Motion Transfer

Motion transfer is another important aspect of a mattress, especially if you share a bed with someone.

There is nothing worse than being rudely woken up anytime your partner jerks, turns or gets out of bed. And my husband is really bad about that.

I found the Alexander Select medium-firm to be as good as any online mattress I’ve tried at inhibiting motion transfer. I never noticed my husband’s twitching around, whether I was awake or asleep.

↑ Table of Contents

Hot/Cold Issues

If you need a mattress that keeps your body temperature regulated and even, the Alexander Signature Series is a great choice.

The combination of a breathable and convoluted foam throughout the construction really helped to keep my bed temperature cool and even.

I did not experience any hot or cold pockets, so I didn’t need a mattress pad.

For a mattress-in-a-box, the Alexander Signature Series is a premium product, to be sure. Prices for the Alexander Select range between $999 and $1,399.

I think the best way to view the Alexander Signature Series is to compare it against Tempurpedic or any other expensive big brand mattress. Compared with them, the Alexander is an outstanding bargain. It performs at least as well, for a much lower price.

The cheapest Alexander starts at $899 for a Twin size.

Here is the full price list:

Twin size $899
Twin XL  $999
Full size  $1099
Queen size  $1199
King size  $1399
California King  $1399

Shipping and delivery are free within the US.

You can also get a discount through the various promotion codes provided by Nest Bedding’s partners.

If you have good credit, you can also take advantage of financing provided by the company. This is not something you will get with most other mattress brands. The financing works by letting you pay for the mattress in easy monthly installments over a 3, 6 or 12 month period.

The Alexander mattress comes with an exceptionally long 20-year warranty.

This warranty extends only to the original buyer for the length of time he or she owns the mattress. This means that transferring ownership to someone else voids the warranty.

The warranty covers sagging beyond one inch and unraveling of the seams.

It is important to note that poor care of your mattress may lead to voiding of the warranty. The company specifies that the mattress must be placed on a rigid, firm and smooth surface like a box spring or a slated platform.

Certain defects such as natural fading of the material, blemishes, soiling and burns are not covered by the warranty.

100-Night Trial

Nest Bedding has one of the best return policies you will find.

You are asked to spend a minimum of 30 days with your mattress to break it in and to judge its suitability. You cannot make a return before the thirty days are over.

The in-home trial period is 100 nights. This gives you more than enough time to be sure whether you have bought the right mattress.

Buying the Alexander mattress is essentially a no-risk investment. If you find the mattress is too hard, too soft or just not to your liking, simply return it.

If you live near any of their stores in CA, the mattress will be picked up from your home. If you are further away, then the company will find a charity for you to donate the mattress to.

You do have to show proof of donation to receive your refund.

  • The same premium quality as Tempurpedic, but a whole lot cheaper.
  • No off-gassing or new mattress smell
  • Premium materials and design.
  • Three firmness levels to choose from. Choose the mattress that suits you best.
  • Financing is available from the company.


  • For people who love memory foam, the latex foam used in the Alexander mattress may not be what you are looking for.
  • For those who want a fully certified organic mattress, this is not it. Try other all-natural brands by Nest Bedding. A good example is the Q3 Latex Mattress.

The Alexander Signature Series Mattress is Perfect For You If…

  • You care about a premium organic mattress that is superior in quality, uses non-toxic components, is guaranteed to last for more than a decade and comes with great customer service.
  • You need a softer or firmer mattress than the one-size-fits-all brands like Casper, Bear and Leesa offer.

The Alexander firm mattress is best for heavier people who require a mattress that can withstand pressure without losing support or experiencing too much sinkage. You may also find this mattress ideal if you tend to sleep on your stomach

The Alexander medium is ideal for 90% of us. If you are of average weight and are a side or back sleeper this is what you need.

The Alexander soft mattress will work for the few people who are extra sensitive to pressure points, like full-time side sleepers. This includes those with back and joint problems and those who are very light and bony.

↑ Table of Contents


The Alexander Signature Series is a quality, premium online mattress that performs as well or better than high-end brands like Tempur. And it costs a LOT less.

For example, a queen-size Tempur Cloud Prima costs $1,700, but the Alexander only costs $1,199.

If you’re looking for a step-up from the bland one-size-fits-all mattresses that most bed-in-a-box companies offer, then the Alexander might just be your ticket.

It’s hard to go wrong with a 20 year warranty, too.
