Casper vs. GhostBed vs. Purple: which of these all-foam mattresses is right for you? Our sleep experts are here to help you decide.

»

Not all foam mattresses are created equal, as you’ll see in this comparison of the Casper vs. GhostBed vs. Purple bed. One is great for alignment, another is sturdy enough for heavier sleepers, and the latter is designed with pressure relief in mind – but which of these three mattresses is the best fit for you?

In this comparison, we’ll go over all the details, from each bed’s firmness, to bounce, to pressure relief and support. By the time you’re done reading, you should know which of these beds is your best match.

Comparing Firmness, Support & Feel

Firmness

We rate mattress firmness from 1 to 10, where 1 is as soft as a cloud and 10 is as firm as it gets. The Casper, GhostBed, and Purple are all similar in their firmness levels, ranking at a 6 out of 10, 6.5 out of 10, and 6 out of 10, respectively. This makes them all medium-firm mattresses, which means they should work for a variety of sleepers.

Support

The Casper, GhostBed, and Purple are all supportive beds but in varying ways and for different people.

The Casper is especially supportive for those with back pain, as it is zoned to be firmer beneath the hips to keep the spine better aligned. The GhostBed has a more substantial base and should better support heavier-weight sleepers. The Purple has reinforced edge support, so people can use the entire surface of the mattress – a plus for couples.

Feel

All three mattresses will be delivered to your door, compressed in a box. Each of these bed-in-a-boxes will take some time to decompress. Once they do, though, they’ll have slight differences in feel.

The Casper should feel cool to the touch, and when you lie on it, you’ll sink into its top layers. The GhostBed feels firmer and bouncier but still cool. Lastly, the Purple also feels springy, but when you lie on it, you’ll feel its grid-like construction contouring your body.

Comparing Sinkage and Bounce

None of these three mattresses are your typical “deep hug” memory foam beds. The Casper is probably the most similar to that because it offers a good amount of sinkage. However, the foam in this bed is still quite responsive, so you’ll sink in, but you won’t feel trapped in the layers.

The GhostBed is the bounciest of the three since its top layer is made from latex, a naturally buoyant material.

The Purple will feel uniquely contouring and springy at the same time; you’ll sink into its pressure-relieving grid, but it will spring back into shape as soon as you move.

Comparing Motion Transfer

Motion transfer describes how much motion you’ll be able to feel on your side of the bed when somebody is moving on the other. This is especially important for those who share a bed, and even more so for light sleepers who share a bed.

Luckily, since none of these mattresses include coils (as an innerspring or hybrid mattress would), they all excel at isolating motion. This means they’ll absorb most of the motion, so you shouldn’t feel your partner (or furry friend) getting up from bed or changing positions through the night.

Comparing Cooling

All-foam mattresses aren’t known as the most cooling of beds. Without any coils for breathability, it can be a recipe for a hot night’s sleep. Luckily, all three of these beds take cooling into consideration in their construction.

The Casper uses a top layer of perforated foam, so air can move quickly through it. The GhostBed sleeps even cooler since it uses latex, a naturally temperature-neutral material, as well as gel-infused memory foam. Both of these layers are near the top and closer to your body to wick away heat.

Finally, Purple’s unique Hyper-Elastic Polymer™ material is temperature neutral, so heat shouldn’t build up around your body while you’re sleeping.

Comparing Construction (Materials & Quality)

Casper Construction

This bed in a box will arrive at your door, compressed in a box. Once the Casper decompresses, it stands 11 inches tall. It consists of three foam layers, all wrapped in a durable but soft polyester cover.

• Beneath the cover is the first foam layer. This AirScape™ foam is perforated for coolness as well as a bit of bounce.
• The middle foam layer is made up of 2 inches of Zoned Support™. This memory foam is zoned to be firmer beneath the hips, where most people carry more weight, and softer beneath the shoulders and knees. This will not only create some excellent pressure relief, but it will keep your spine in a healthy and neutral alignment through the night.
• The base layer is made up of a dense and durable foam, which creates the overall foundation for the Casper mattress and provides some more support for the sleeper.

GhostBed Construction

The GhostBed also arrives compressed in a box. Once it fully decompresses, it will measure 11 inches tall.

Starting from the outside, the cover is made from a blend of polyester and viscose. It is breathable and designed to wick away moisture. Beneath the cover are three layers of foam.

• The top layer is made up of 1.5 inches of Continuous Aerated Latex foam. This is a naturally cooling and responsive material.
• The middle layer is 2 inches of gel memory foam. This gives the bed some deeper pressure relief and acts as a transition layer between the top and the base. It is also infused with gel to reduce heat retention.
• The base is 7.5 inches of high-density foam, which gives the mattress a durable structure. It should also absorb and evenly distribute your body’s weight while providing a good amount of support for proper spine alignment.

Purple Construction

Once the Purple decompresses, it will be the thinnest of the three beds, measuring just 9.5 inches tall. The cover is made of a SoftFlex material; a blend of polyester, viscose, and lycra. It is soft and breathable and should easily adapt to the unique grid layer beneath it.

• Below the cover is Purple’s unique “pressure-erasing” grid. It is made of 2 inches of Hyper-Elastic Polymer™, a highly durable and flexible material. This grid-like structure evenly distributes weight across its surface, which is why it is so good at relieving pressure.
• The middle layer is made up of 3.5 inches of medium-soft polyurethane foam. This layer not only provides some extra comfort and pressure relief, but it acts as a transition layer between the top and base of the bed.
• The base layer is 4 inches of medium-firm support polyurethane foam. This layer gives the bed its shape and durability.

Comparing Company Policies & Price

• Warranty – Both the Casper and Purple beds come with a 10-year warranty, but the GhostBed comes with a 20-year warranty.
• Shipping – Casper includes free shipping within the U.S. and Canada, whereas GhostBed’s shipping is free within the U.S., except for Hawaii and Alaska. Purple also has free shipping within the contiguous U.S. and also ships to Canada through their partner Sleep Country Canada.
• Trial Period – The trial periods for these three beds are all nearly the same. For the Casper and Purple, you can try the bed for 100 nights. With the GhostBed, you can try the bed for 101 nights.
• Returns – Casper and GhostBed both require you to try out your new bed for 30 nights to see if it works for you. If it doesn’t after that, you can return it within your sleep trial window for a full refund. With Purple, you’ll need to try it out for 21 days before you can initiate a return, and unlike Casper and GhostBed, you’ll need to pay for shipping if you return the Purple.
• Price – These beds are similar when it comes to price. However, GhostBed is the more expensive of the three.
