Casper was one of the first online-only mattress sellers and remains the largest. They are often credited with creating the revolution, and has gained a reputation as a maker of a simple but affordable, high quality foam mattress.

Purple had its origin on Kickstarter, where they raised more than a $100,000 to launch their brand. They created a uniquely designed mattress that quickly became one of the most popular foam mattresses sold online.

After launching in 2015, Purple has attracted thousands of rave reviews with users praising its truly unique top layer for its unmatched level of support and comfort.

But can Purple out-perform a brand that is practically synonymous with online mattresses?

What’s In This Comparison

In this new mattress showdown, you will learn how the Casper and a newer rival, the Purple mattress, compare in a number of areas including price, warranty, comfort, construction and sleeping experience.

My goal here is not to tell you which mattress is the best, but instead to give you the details you need to make a confident choice between these two mattresses.

So, let’s get to it.

Buy the Purple Mattress if:

  • You need more support and pressure relief (back pain, etc.).
  • You and your partner have different sleeping preferences.
  • You’re willing to try a new type of mattress: the feel is truly unique – and very nice.

Mattress Construction


Instead of the traditional memory or latex foam in the top layer, the Purple mattress uses a special type of material it calls Hyper-Elastic Polymer.

This is a highly responsive foam that has applications in a wide variety of areas including hospital beds, chair cushions, and toy balls.

But the most interesting thing is not even the material but how it is designed. Instead of the usual blocky design, the polymer takes a grid-like structure with rising columns intersecting across the surface of the mattress.

When you lie on the mattress, you interact with these columns & walls, which collapse or stay upright depending on the amount of pressure on them. This provides a really unique two-phase system of support.

For example, the polymer grid will collapse around a high-pressure point like your hips, which really helps if you are a side sleeper. This ensures your hips don’t press painfully into the mattress.

On the other hand, the walls will stay upright where your back lies, thus providing more support and aligning your back.

Only the top layer adapts to your specific body type and sleeping position.

Underneath there are 3.5 inches of transitional polyurethane foam and 4 inches of foundational foam to provide more support, ensuring you don’t sink excessively into the mattress especially if you are heavy-bodied.

The cover is made of polyester, viscose, and lycra. Which makes it soft, breathable and stretchy.

Casper also uses a proprietary foam at the top. It uses an open-cell structure, which boosts air circulation and ensures the mattress stays cool through the night.

The second layer consists of pressure-relieving memory foam. Its work is to contour around your pressure points and create a comfortable hug around your body. The third layer is a thin slice of foam Casper calls adaptive transition foam. Together with the base layer, they provide compression support to the sleeper.

The top of the cover is made from 100% polyester, making it both soft and breathable.

Overall, comparing Purple Mattress vs. Casper regarding design and construction, Purple has a slight edge. The Hyper-Elastic polymer at the top is one of a kind. It combines support, pressure relief and temperature control into one great sleeping experience.

Comfort and Firmness


Purple Mattress - cover

Purple could have made two or three mattresses with different comfort levels to fit different sleeping needs. But there was no need. The top polymer layer does a great job adapting to everyone’s unique sleeping preferences and needs.

The walls of the grid-like structure respond to the specific pressure on them. They can collapse to provide pressure relief or hold up to provide support.

Regarding firmness, Purple falls in the medium-firm range (6-7/10) though slightly on the higher side. So if you like to sink into your mattress, Purple is not ideal for you.

One other thing you’ll love is how responsive (bouncy) the mattress feels. It’s better than the Casper mattress for sex.

Casper feels slightly softer than Purple. This is because of the memory foam in the second layer. It provides pressure relief and contouring, enveloping your body in a comfy hug.

So if you want a mattress that feels softer and plusher, try Casper. On the downside, it does not feel as bouncy as the Purple mattress.

The third and fourth layer counter the soft upper layers ensuring that you don’t sink in too much that support is compromised.

Sleeping Experience


Leesa vs Purple Mattress

There is only one word to describe Purple’s sleeping experience: heavenly. With its ability to adapt to any situation, the Purple mattress is perfect for all situations and everyone. It is especially great for couples with different sleeping needs.

The mattress may feel a bit firm when you lie on it, but it softens up a tiny bit as it adapts to your body and sleeping position. As I mentioned, it also feels quite bouncy but with minimal motion transfer (thanks to the motion-isolating grids).

Regarding temperature control, the cover and the grid structure of the top layer work well in keeping heat away from the surface of the mattress even on particularly warm nights. For those who tend to sweat a lot at night, the circulating air keeps the mattress dry and smelling fresh.

The Casper mattress feels plusher than the Purple. The memory foam layer produces more pronounced sinkage which creates a luxurious hug around your body. Immediately you lie on the bed, you’ll feel the memory foam layer contouring around your hips, back and shoulders.

The top open-cell foam layer keeps the surface cool and dry while the foundation layers provide extra support to prevent the mattress from turning into a swamp.

The main downside of Casper applies to sleepers with heavier physiques. Because of the fairly thin and softer comfort layer (3 inches in total), the dense base layers will be more noticeable. This could create painful pressure points, making your sleep uncomfortable.

If you are on the higher side regarding weight, I’d recommend the Purple mattress. It is better at adapting to different body types. If you have existing back problems, the Casper is a better choice. It provides more pressure relief.

Warranty and Returns


Purple Mattress layers

Like most other online mattresses, Purple offers a 10-year warranty. You can be confident that the mattress will last at least that long. The warranty terms and conditions are standard. It only covers the original buyer; it is voided if the mattress is used wrongly and only material and workmanship defects are covered.

But there is one very important condition in the warranty you should note: you are responsible for transport and inspection costs should you decide to request a replacement or repair. Purple will only cover the repair/replacement costs.

The mattress cover is under a different warranty, which runs for two years. Like the mattress, transport costs are on you, but the company takes responsibility for the replacement or repair.

As for returns, you have 100 nights to test the mattress at home and decide whether you want to keep it. Purple recommends sleeping on it for at least 30 nights to allow your body to acclimate to the new feeling.

If you decide to return it, Purple will arrange how it will reach a charity organization or get recycled depending on the local code. But don’t try to get it back into the box. Just make sure it is clean and free from any damage.


Casper too has a standard 10-year warranty. But they differ slightly when it comes to costs. If you decide to request a repair or replacement and Casper agrees, shipping costs will be split between the two of you.

If there are any shipping costs involved in returning the mattress, Casper will pay them. But you are responsible for shipping costs when the repaired or replaced mattress is sent back to you. Check the full warranty at their official website for all other terms and conditions.

The return period is 100 days from the date of delivery. The returned mattress will be given to a church or charity organization with whom Casper will arrange a pickup. In some locations, however, the law requires that used mattresses be recycled.

Whatever happens, Casper will ensure the whole process goes smoothly and you get a full refund.

Shipping and Delivery Options

Purple provides free standard shipping to 48 continental states of the US. For those ordering from Alaska, Hawaii or Canada, a shipping fee will be added at checkout.

But if you have any special delivery request or instructions, feel free to reach out to Purple’s customer support and see if they can accommodate your needs and whether it will cost you extra.
