The clash of the Titans: Mattress Edition. Both manufacturers have revolutionized the world of online mattresses in their own, unique fashion. Casper is a renowned-brand with an impressive track record that rose to fame in a matter of months.

Purple has earned its coveted spot in the market by employing a one-of-a-kind, proprietary material that is found in the comfort layer of the model. Considering that both mattresses come at a similar price point, it’s hard to decide which one to choose.

That’s where we come in. If you’re struggling to make a choice, we’ve examined every nook and cranny of both models to make it easier for you.

By analyzing all critical aspects of each model, we were able to establish who is the clear winner here. But, before we reveal that to you, let’s dive in more deeply into the performances of these two flagship mattresses.

In addition to this comparison, we recommend reading our review of each brand:

Mattress Construction Comparison


This is a 12″ all-foam model of medium firmness. It’s designed to cater to most types of sleepers. Casper’s cover is cozy and soft to the touch. The polyester cover is removable. The mattress features four layers in total.

The model has one comfort layer. The top layer is made of a proprietary material that has a latex-like feel, which makes this casper vs purple battle even more indecisive as the other model also has a proprietary, patented comfort layer.

The transition layer actually consists of two layers. One of them offers one-of-a-kind zoned-support. It provides tailored support to the hips and shoulders. It is particularly great for side sleepers.

The base is made of high-density polyfoam. It lends the mattress’s longevity and sturdiness. The foundation layer also helps the model retain its shape during its lifespan.


This 10″ model comes with a very interesting grid layer that you won’t see elsewhere on the market. The purple vs casper showdown keeps getting better and better. Its stretchy cover does a great job of wicking away moisture.

It’s made of lycra, viscose, and polyester. The blend is usually found in athletic clothing. The comfort layer features the patented hyper-elastic polymer.

The grid sort of collapses as you lay on top of it. It contours to the body without feeling obtrusive. Its cells buckle and bend in a unique fashion that provides targeted support and pressure relief.

The transition layer is made of high-density polyfoam. It’s a bit on the firm side in order to secure extra support. The bottom layer features poly-foam. It lends overall stability to the bed.

Mattress Firmness Comparison


When it comes to firmness, the purple mattress vs casper battle is a tie. We score both models at 6.5 on our 1 to 10 firmness scale. Casper offers a medium-firm feel. It’s a good choice for indecisive sleepers who are not sure about their preferred sleep style.

If you’re a combo sleeper, this might be the bed for you. When sleeping on the back, you should feel even weight distribution. You can rest assured that your spine will stay in neutral alignment.

The zoned support provides an excellent feel to side sleepers. One feels sturdier support under the hips and soft contouring around the shoulders. The manufacturer has tackled the problem side sleepers face quite well.

Stomach sleepers should feel all-around support. However, heavier stomach sleepers may need something firmer. For them, the support in the hip area might not be the best.


As mentioned, both mattresses have the same firmness level. However, the feel slightly differs. This model has a certain rubbery quality because of the unique grid. It offers a contoured feel.

However, back sleepers don’t have to worry about sinking in too deep. The bed doesn’t excessively cardle back sleepers. Instead, it makes them feel like they’re floating on top of it. Side sleepers, on the other hand, can expect to feel targeted pressure relief.

When it comes to pressure relief, this bed is right up there with the best memory foam mattress models. Just like its competitor, it may not be the best choice for strict stomach sleepers who are a bit on the heavier side. However, if you are a stomach sleeper of average weight, you can rest assured you’ll get even weight distribution.

Sleep Experience

Although they differ in certain areas, there’s no doubt we’re dealing with two high-end models that both provide a stable balance of support, comfort, and resilience. One thing is clear, whichever you place your bet on in the purple vs casper showdown, you won’t come out as a loser.

Both models offer a true all-foam feel with all of its benefits, but even some of its downsides. All-foam materials have their weaknesses, just like all other types of beds.

The two manufacturers didn’t neglect to address those common all-foam issues. However, since the two beds employ different materials, it’s apparent that their approach to the problems differs.

Motion Transfer and Edge Support

Both models do a terrific job of dealing with motion transfer, making it even more challenging to choose the winner of the casper vs purple comparison. However, Casper’s motion isolation is slightly better. One can still feel some motion transfer on the Purple, but nothing that’ll disturb your sleep.

Both are a solid choice for restless sleepers and couples. When it comes to edge support, neither of these performs exceptionally well. That’s just the nature of foam materials. They are incapable of reinforcing the edges.

That’s usually not a deal-breaker. Lack of edge support may make sitting on a bed uncomfortable, but that doesn’t necessarily go for sleeping. If you are planning on sleeping with a partner, it’s best to go with a bigger model so that you wouldn’t have to put pressure on the edges.


All-foam beds are not famous for excellent temperature control. Such materials tend to trap heat when the body sinks in too deep.

Since Casper doesn’t trap the body, it also does not retain heat that much. Unless you live in a particularly hot climate, this is a safe choice. The model employes open-cell technology, which helps significantly with heat regulation. Most sleepers do not find the model to sleep hot.

However, Purple is the clear winner when it comes to sleeping cool, without a doubt. That’s mostly thanks to the proprietary material. It does an excellent job of promoting airflow. If sleeping cool is your biggest concern, you’re better off with the Purple.

Sinkage and Bounce

Purple’s comfort layer makes it a very resilient mattress. It returns to its original shape quite quickly thanks to the hyper-elastic polymer. The grid also enhances its bounciness.

Purple’s bounce allows you to reposition easily and makes you feel a bit like you’re floating. The mattress cradles the sleeper quite nicely, without letting them sink in too deep.

Being able to move around the bed with ease is vital for combo sleepers. As for Casper, there is some bounce to it, but it doesn’t do as good a job as Purple when it comes to springing back to its original shape.

The Purple is a better choice if you prefer a bed with a more springy feel. When it comes to sinkage, the latex-like performance of Casper prevents you from sinking in too deep. Both models are the same in that area.

Off-gassing and Smell

Like all all-foam beds, you can expect both of these to emit a specific smell when unboxed. Both are CertiPUR-US certified, so there are no reasons for concern. The smell might be unpleasant, but it’s not harmful.

So, when it comes to off-gassing, there’s no winner or loser in the casper vs purple mattress comparison. If you want the smell to go away in a few hours, you should place the bed in a well-ventilated room. Otherwise, it might take a couple of days for the smell to air out.


How well a mattress supports different parts of the body depends on its responsiveness, among other things. Think of it as tailored support. Responsive models cushion the parts of the body that need the most support.

Responsiveness can be instrumental as good responsive mattresses promote neutral spinal alignment. The good news is, both of these models are very responsive.

However, they are not responsive in the same way. Casper contours to the body in a well-balanced manner. It is not too plush. Casper’s two topmost layers are designed to ensure proper responsiveness.

As for Purple, its signature feature, the Purple Grid, compresses to the sleeper’s weight proportionally. It doesn’t contour to the body as well as Casper does, though.

However, you can count on it to provide tailored cushioning and proper spine, neck, and back support. Casper’s comfort layer is an inch thicker. It ensures enough support for individuals who weigh over 230lbs. If you are a bit heavier or have very sharp pressure points, Casper might be a better choice.

Mattress Shipping and Trial Period

Purple ships rolled into a bag. It comes with convenient handles on each side. Casper arrives compressed and shipped in a box. Both manufacturers are pioneers of the bed-in-a-box industry.

So, both are bed-in-a-box models, and both ship free. However, Purple doesn’t offer white glove delivery, while Casper’s white glove delivery is only available in some areas and costs extra.

Purple ships to the USA and Canada. Casper ships to the USA, Canada, and the UK. Both come with a 10-year warranty. That’s pretty much the industry standard.

Purple comes with a 100-night trial. However, customers are required to use the model for 21 nights before they can return it. If you want to return it, you won’t have to pay an extra fee. The company picks it up.

Casper also offers a 100 night trial, but without such a contingency. In case you want to return it, it’s free of charge, and the company picks it up.


We want you to come to your own conclusion based on your preferences, so let’s take a closer look. Purple is a better choice if you want to sleep cool. It does a better job of promoting airflow.

Its science-driven design offers a new sleep experience that differentiates it from the rest of the high-end models in its category, including Casper. Purple is also a better choice for restless and combo sleepers as it enhances movability.

Casper may be a better choice for sleepers who are a bit on the heavier side. It offers exceptional responsiveness that ensures great support to all the major pressure points. It also comes with a more traditional, all-foam feel. And, unlike Purple, Casper has a twin size option.

Both models are exceptionally versatile. In that regard, both mattresses are champions in the casper mattress vs purple mattress showdown. No matter how you like to sleep, you can rest assured you’ll feel comfortable and well-supported whichever option you go for.
