Purple Mattress Review

Construction

Purple is a 9.5″ mattress made from 3 layers of polymer and foam. Atypical to most mattresses, Purple uses a highly engineered hyper-elastic material in addition to 2 layers of foam.

  • Top layer (cooling & comfort) – 2″ layer of hyper-elastic polymer. This layer is designed to provide remarkable cooling as well as pressure point relief. The hyper-elastic polymer is designed with “smart grid” technology, which helps to keep the sleeping surface extremely cool and comfortable.
  • Middle layer (transitional support) – 3.5″ of polyurethane foam. This layer works hand-in-hand with the top layer to provide transitional support as well as the deep compression support for heavier sleepers.
  • Bottom layer (foundation) – 4″ of polyurethane foam. This layer acts as the foundation for the mattress.

Cover

The Purple’s cover contains a combination of polyester (69%), viscose (27%), and polyester-lycra (4%). The blending of these materials makes for a highly breathable cover. Additionally, the cover is soft and has the ability to stretch quite easily. As I pulled the cover from several different angles it had no trouble popping right back into place. The cover of the Purple mattress works extremely well with the hyper-elastic polymer smart grid design to provide a very cool sleeping surface.

Aesthetically, the cover has a great mix of modern and traditional style. As an all white cover, you get the traditional look. On the other hand, the diamond pattern scattered across the mattress adds a little flavor to the traditional look. In addition, Purple embossed their logo to all 4 sides of the mattress, giving the cover a more modern finish. Granted, the cover is nothing extraordinary but Purple did a great job of taking a basic all white cover and sprucing it up.

Firmness, Feel, & Support

Purple has one of the most unique feels that I have tested to date. Coming in at a 6-6.5 out of 10 on the firmness scale, with 10 being the most firm, this is a mattress designed to fit the needs of the vast majority of sleepers.

As stated above, Purple is quite unique in terms of feel. Their smart grid design provides a feel that I have not experienced on a mattress yet. The polymer material has properties similar to that of latex, but with a feel all their own. When it comes to support, Purple is great. The mattress has the ability to dissipate the pressure points your body tries to create while remaining comfortable. Between my wife and I, we cover all sleeping positions and both felt as if the Purple did an excellent job maintaining stable spine alignment in addition to full body support.

One of the most interesting characteristics about Purple is its ability to act and feel different for every sleeper. As a lighter sleeper (<130 pounds) you will tend to feel more of a floating feeling while lying on the mattress. There will be less pronounced contour as well, due to the minimal amount of sinkage you are experiencing.

As weight increases (130-150 pounds) you will experience a slight amount of sinkage and body contour. This trend increases all the way up to 300 pounds. Needless to say, the heavier you are the more hug you will receive. Yet, regardless of weight, the support from the Purple mattress will not change. Whether you’re 100 pounds or 300 pounds, Purple provides great adaptive support for all weights and body types.

The most impressive feature of the Purple mattress is its cooling capabilities. The smart grid design created by Purple is quite the cooling system. The smart grid looks more like a webbed design with air pockets covering the entire surface. These air pockets allow the foams below to breathe much easier, creating a cool sleeping surface. Purple is one of the coolest mattresses I have tested to date. In the image below, you may notice a white substance in between the pockets of the smart grid. This is a type of baby powder. The baby powder is used to soften up the noise the hyper-elastic polymer would otherwise create.

Personally, I’m a fan of the Purple’s feel. To top things off, Purple’s bounce is great. If you’re looking to excite things in the bedroom, this mattress is a great choice with regards to amorous activity. Tacking onto that thought, the motion transfer of Purple minimal. So while you have the ability to enjoy intimate times, you will also reap the benefits of sleeping undisturbed.

Casper Mattress Review

Construction

Casper is a 9.5″ all foam mattress built from 3 separate layers.

  • Top layer (comfort & cooling) – 1.5″ of latex foam. Latex has good bounce, sleeps cool, and provides much of the comfort and feel for the mattress.
  • Middle layer (support) – 1.5″ layer of memory foam. Placed below the latex to help prevention heat retention issues. Creates much of the support and pressure relief for the mattress.
  • Bottom layer (foundation) – 6.5″ of support foam. This layer strictly acts as the foundation for the mattress.

Cover

The Casper offers the two-tone cover that seems to have become the staple aesthetic for most mattresses. The top portion of the cover is made up of 100% polyester and is quite porous. The blend of these two qualities work to provide a cooler sleeping surface. You’ll want to be careful moving the Casper. While the side panels are a bit sturdier, the white fabric on top is prone to damage. While moving my Casper a while ago it got caught along a corner and ripped several threads out.

Firmness, Feel, & Support

The Casper lands at a 6 out of 10 on the firmness scale, with 10 being the most firm. Similar to Purple, Casper is designed to fit the needs of most sleepers. With that said, the firmness level of the Casper will change depending on the weight of the sleeper. If you’re a heavier sleeper, Casper will feel more like a 7 out of 10 on the firmness scale. This is due to the increased sinkage, putting the sleeper in direct contact with the more dense, harder foams.

Casper is a 6 out of 10 on the firmness scale (where 10 is the most firm). Heavier sleepers may find it is closer to a 7.

As a lighter sleeper (140 pounds) I saw a decent amount of sinkage (1-1.5″) while lying on my back. Granted, the top layer of latex does not give sleepers that trapped feeling that some of the traditional memory foam mattresses can. The latex provides more of a rounded body contour as opposed to the sharper, more traditional contour of memory foam. Although the support of the Casper is average, the top layer of latex does provide adequate bounce and cooling.

Should I buy the Purple or Casper Mattress?

Finally, everything boils down to the most important question…should you buy the Purple or Casper mattress? After sleep testing each mattress, I have come to the conclusion that Purple is the outright better choice. The hyper-elastic polymer top layer in addition to the multiple layers of polyurethane foam simply make a more supportive, cooler, and higher performance mattress than the Casper.

I would recommend the Purple mattress to sleepers who:

  • Want a medium firm feel – the Purple mattress falls at a 6-6.5 out of 10 on the firmness scale, with 10 being the most firm. The firmness levels can vary depending on body type / size. The heavier you are the deeper you sink, providing even more pressure relief.
  • Want better material / build quality – the materials in the Purple are simply better than the Casper. Purple uses 5.0″ of comfort materials vs. Casper’s 3.0″. That 2″ makes a massive difference. Additionally, the polymer material outperforms Casper’s latex in almost every functional area. Lastly, the cover feels better made and more durable in my opinion.
  • Want a cool mattress – Purple’s smart grid polymer design has a plethora of air pockets that create an extremely cool sleeping surface. Additionally, the cover of the Purple is thin, which makes breathability much easier for the mattress. Out of the ~50 mattresses I have tested to date the Purple is without question one of the most cool and is notable more cool than Casper.
  • Want great bounce – the hyper-elastic polymer top layer provides a great amount of bounce for the mattress. The polymer has no trouble returning to its original shape immediately after pressure is applied. This material reacts quicker than latex and provides better bounce, responsiveness, and edge support, making both sleep and sex on the Purple a much more enjoyable experience.
  • Want a rounded contour – similar to latex, Purple has a rounded contour versus the sharp, memory foam contour. This mattress displaces your body weight to the polymer around it, providing the rounded contour.

If you still think the Purple just isn’t right for you I would strongly advise caution on simply going with the Casper. While Casper may be an upgrade over your current mattress it is inferior to a number of similarly priced online mattresses. Leesa, Brooklyn Bedding, and GhostBed are all superior options to the Casper if you certain you want to go with an all foam design.
