Firmness And Feel Differences
The Casper and Purple are quite different in regard to their firmness and feel. We’ll look at just how firm these mattresses are and how that will differ for people of different sizes.
How Firm Are The Casper And Purple Mattresses?
To us, the Casper mattress feels like a 7/10, just a bit firmer-than-average – the top polyfoam layer is quite soft as are the head and foot of the transition layer, but the support layer is very firm. However, because the mattress is firmer toward the center, the Casper will feel firmer and more supportive when back sleeping and stomach sleeping and softer when side sleeping. Also, larger people might feel like the Casper is even firmer as they push further into the mattress and feel the support layers beneath.
The Purple felt a bit softer to us, and we put it at a 6.5/10, about medium in terms of firmness. However, the firmness of this mattress will definitely depend on someone’s weight. Larger people will really activate that gel grid on top, and they should feel like the Purple is softer; lighter people might not be heavy enough to activate the gel grid, so the mattress could feel quite firm to them.
Sleeping On The Casper And Purple Mattresses
Back sleeping on the Casper, the mattress offers us the perfect balance of comfort and support, as our hips sink into the top foam layers, and the base foam holds up our bodies. The zoning in the transition layer also provides extra support under our lumbar area so, all in all, we feel fantastic while back sleeping.
Side sleeping on the Casper, we are feeling decent pressure on our shoulders and hips because the top polyfoam layer is soft and the transition layer is softer under the shoulder area.
Stomach sleeping, the Casper is too soft for us and, even with its Zoned Support system, the Casper is not providing us with enough support under our hips. We feel as if our hips are sinking in too far, and this could cause lower back strain over time.
Moving to the Purple, the mattress is also an exceptional fit for back sleeping. The gel grid only collapses under our butt and hips, and we feel the mattress support the rest of our bodies.
Side sleeping, we are also feeling some good pressure relief on our shoulders and hips because the gel grid collapses under those areas but nowhere else. However, as we will discuss below, this might feel different for lighter side sleepers.
Stomach sleeping, the Purple mattress does not collapse at all under our hips, and we feel good overall support. The Purple stays flat and supportive and it definitely feels firm enough for long-term stomach sleeping.
What Do The Casper And Purple Mattresses Feel Like?
The Casper mattress features a balanced foam feel and exhibits a fair amount of bounce. The polyfoam in the top layer is soft yet responsive, so we sink in but have no trouble moving around on the mattress.
The Purple has a very unique feel that is squishy and gel-like but also supportive and firm. The mattress stays flat and supportive until we apply enough pressure and then that specific area collapses.
Average Weight Sleepers – 130 lbs – 230 lbs
Back sleeping, average weight sleepers should feel comfortable and supported on the Casper mattress and, side sleeping, they should feel some good pressure relief on their shoulders and hips. Stomach sleepers who are closer to 130 lbs should get enough support on the Casper, but those who are closer to 230 lbs might need something firmer.
Back sleeping on the Purple, most average weight sleepers should find it to be a good fit, but those who are closer to 130 lbs might feel like the Purple doesn’t let their hips sink in far enough. Side sleepers who are closer to 230 lbs should collapse the gel grid and feel little pressure on their shoulders and hips but, if they are on the lighter side, they might feel like the mattress is too firm as their weight won’t be enough to activate the gel grid. Stomach sleeping, most average weight sleepers should feel well supported on the Purple.
Heavyweight Sleepers – Over 230 lbs
The majority of larger people should feel well supported when they are back sleeping on the Casper mattress, but those who are over 300 lbs might still need a mattress with coils in the support layer, such as the Casper Wave Hybrid. Side sleeping, most larger people are going to experience some significant pressure on their shoulders and hips and, stomach sleeping, they will also need a more supportive mattress.
Larger back sleepers should feel good support on the Purple mattress, but much larger back sleepers might want to consider the Purple Hybrid Premier mattress with coils. Side sleeping, larger people should feel little pressure on their shoulders and hips. Their weight will collapse that gel grid, and they should feel cradled by the mattress. Stomach sleeping, a good deal of heavier people should get enough support under their hips.

Lightweight Sleepers – Under 130 lbs
Back sleeping on the Casper, lightweight people will experience the proper balance of comfort and support. Side sleeping, they should feel little pressure on their shoulders and hips and, stomach sleeping, they should get enough support. The Casper is really one of the best mattresses for lightweight sleepers.
Back sleeping and side sleeping on the Purple, lighter people will most likely find the mattress to be too firm because their weight just might not be enough to put that gel grid to work. However, when lighter people are stomach sleeping, they should get enough support.
Mattress Construction Differences
Let’s look under the hood of both the Casper and Purple mattresses. We’ll focus on each layer one by one and see what the material differences are.
The Casper features a soft cover that is made from recycled materials – it is knit, stretchy, and breathable. The Purple has a SoftFlex cover that is also stretchy and breathable.
The Casper features a layer of responsive polyfoam that contains AirScape technology – this means the foam is ventilated for more airflow. Below that, there is a layer of memory foam with Zoned Support where the center of the layer is firmer than the top and the bottom.
The Purple features a proprietary Purple Grid right that is made of something called hyper-elastic gel polymer and is durable, supportive, and also pressure relieving. Below that, there is a layer of thick comfort foam.
The Casper features a standard base foam in its support layer, and the Purple also features a supportive base foam layer.
The Casper is 11″ thick, and the Purple is 9.25″ thick.

Casper Vs Purple Performance Differences
How do the Casper and Purple mattresses compare in terms of cooling, motion isolation, and other factors? To see how they compare to other brands, see our Casper mattress comparisons and Purple mattress comparisons.
Sleeping Hot Or Cold
Both the Casper and Purple feature cooling components – the Casper boasts Airscape technology and the Purple has a gel grid that promotes a great deal of airflow. However, between the two mattresses, the Purple should be the more breathable, cool-sleeping option.
Memory foam is one of the best materials for cutting down on motion transfer and, while the Casper doesn’t feature memory foam right on top, it is in the second layer. Because of this, it seems to handle motion transfer better than the Purple and could be the best mattress for couples.
Edge support is also important for couples to consider because it allows each partner to sleep further apart without falling off the bed. Purple offers better edge support than the Casper, and we feel more supported when we sit and lie down near the edge of the mattress.
It is hard to tell which mattress is actually more durable but, based on our research, we would say the Purple wins out. It seems to be one of the most durable mattress materials we have come across and it should not sag the way some foams are known to do. Make sure to read our list of the best mattresses that won’t sag for more options like this.
We experienced more off-gassing with the Casper mattress, and this is no surprise, as all-foam mattresses often let off a chemical smell when they are first unboxed. That being said, the smell did dissipate after 48 hours.
Moving around on both mattresses, we did not hear any sounds. Neither mattress features coils, which are known to squeak when they get older.
The Casper and Purple should both be good mattresses for sex because they are both responsive, bouncy, and make it easy to move around and change positions. These are all attributes that couples should be looking for in a mattress for sex.
Both mattresses come with a 100-night sleep trial and a 10-year mattress warranty.
