Purple and Casper are two fan-favorite bed-in-a-box mattresses from well-known mattress companies. Find out if the Casper’s traditional memory foam support or Purple’s unique floating feel is better for you.
The Casper is a mixed-foam mattress that combines soft, springy polyfoam with a pressure-relieving layer of memory foam. The original Purple mattress boasts the Purple Grid—a top layer made from a gel-like material that evenly distributes body weight so you feel like you’re floating.
Both the Purple and Casper are best for back and side sleepers under 230 lbs. The Casper is better than the Purple for stomach sleepers thanks to the bed’s middle layer of memory foam. The Purple mattress sleeps cooler than the Casper and has a weightless feel that we think those with joint pain will especially love.

Mattress firmness is measured on a 1–10 firmness scale, with 1 being extremely soft and 10 extremely firm. The right firmness level for your body depends on your weight and sleeping position. Sleepers who rest on their side often prefer a softer mattress that cushions pressure points. Stomach and back sleepers fare better on medium-firm mattresses, since they offer a flatter surface that improves back support.
Your weight is also a factor in firmness preference. Lighter folks tend to need a softer mattress to get enough pressure relief, while heavier people need a firmer mattress for adequate support.
Both the Purple and Casper have middle-of-the-road firmness levels: 6.5/10 for the Purple and 6/10 for the Casper. This firmness works well for most sleeping positions. While the Casper works better for stomach sleepers thanks to extra support for the lower back and hips, both beds are best for people who weigh less than 230 lbs.
Body Type: | BACK SLEEPERS | STOMACH SLEEPERS | SIDE SLEEPERS |
Lightweight (< 130 lbs): | 5 | 3 | 4 |
Average weight (130–230 lbs): | 5 | 2 | 4 |
Heavyweight (> 230 lbs): | 3 | 1 | 4 |
Body Type: | BACK SLEEPERS | STOMACH SLEEPERS | SIDE SLEEPERS |
Lightweight (< 130 lbs): | 5 | 4 | 4 |
Average weight (130–230 lbs): | 5 | 3 | 5 |
Heavyweight (> 230 lbs): | 3 | 2 | 2 |
Motion isolation is an important factor for couples, who can experience disrupted sleep if they feel their partner switching positions or getting out of bed. The Purple minimizes motion transfer very well—as does the Casper—thanks to the naturally low motion transfer rate of foam and the Purple Grid.

Edge support is important for people who have trouble getting in and out of bed and for those who snuggle up along the mattress’s perimeter. The Purple offers relatively good edge support when you lie along the edges, but is a bit less supportive when sitting on the edge or getting in and out of bed. The Casper’s level of edge support is similar, both when sleeping on the edges or sitting on them.
Pressure relief is particularly important for side sleepers whose hips and shoulders need extra cushioning. A bed’s rate of pressure relief is closely linked to the materials used in its comfort layer and how well it conforms to sleepers’ bodies.
The Purple mattress does an excellent job distributing weight throughout the Purple Grid, providing great pressure relief for lightweight and average-weight people. Heavier sleepers may come into contact with the core layers and experience added pressure. The Casper is similar, providing great pressure relief for average-weight and lightweight sleepers, with heavyweight sleepers running into some added pressure as well.
Your ability to achieve spinal alignment on the Casper or the Purple depends on your weight and sleeping position. In general, side sleepers should find sufficient cushioning and spinal alignment on the Purple for the hips and shoulders, and back sleepers will find a neutral alignment. Heavyweight sleepers (more than 230 lbs) and stomach sleepers may experience uncomfortable sinkage that leads to a misaligned spine.
The Casper mattress provides excellent spinal alignment for lightweight and average-weight back and side sleepers. It’s the Casper’s memory foam layer that provides the contouring that aligns the spine in every position. Heavyweight sleepers may experience pressure in their hips and shoulders (especially for side sleepers) or excess sink in their hips (especially for back and stomach sleepers).
If you want the best spinal alignment in multiple sleeping positions, see the best mattresses for combination sleepers.
While gauging mattress durability isn’t an exact science, we’d say the Casper mattress has a lifespan of roughly six to eight years. The support foam, which is relatively thick when compared to other all-foam beds, helps it last a bit longer than average. The Purple mattress will last roughly seven to ten years before a replacement mattress is needed. With the Casper, frequent rotations are recommended to prevent sagging and body impressions.
The cube-shaped pockets in the Purple Grid allow airflow through the top layer, keeping sleepers cool and the absorption of body heat to a minimum.
Casper, on the other hand, maintains a comfortable sleep temperature, but we wouldn’t say it’s one of the best cooling mattresses. The solid-foam base doesn’t promote much airflow, and while the comfort layers do a good job of releasing body heat, they’re no competition for the Purple’s breathable, spacious Grid.
Purple’s claim to fame is its proprietary Purple Grid, a Hyper-Elastic Polymer layer that conforms where the body exerts pressure but doesn’t compress anywhere else. As a result, every Purple mattress model has a “floating” effect that many love.
The stretchy polyester, viscose, and Lycra blend cover flexes along with the Purple Grid, offering even more comfort and breathability. Beneath the grid, a transitional layer of high-density polyfoam acts as a buffer to prevent sinkage. A 4” support foam layer reinforces the mattress.
Cover | Polyester Fabric |
Comfort Layer | AirScape Foam (1.5″) |
Transitional Layer | Zoned Support Memory Foam (2″) |
Support Layer | High-Density Polyfoam (7.5″) |
Mattress Thickness | 11” |
The Casper Original mattress, the brand’s flagship model, is a mixed-foam mattress made with 1.5” of plush polyfoam and 2” of memory foam. Together, these layers create body-contouring and a responsive feel. The zoned memory foam means the Casper is softer at the shoulders and firmer along the body’s heavier core, creating a balanced feel.
The base layer of the Casper is a 7” layer of high-density polyfoam, which stabilizes the bed and prevents the top two layers from sagging. This support layer reinforces the edges to make it easier to get in and out of bed. The Casper has a removable, washable polyester cover made partially from recycled bottles.

Learn More: Purple Return Policy
If you decide to return the bed, you must wait until after a 21-day adjustment period. Purple then issues a full refund and sends someone to your home to pick up the mattress. The Purple bed comes with a 10-year warranty, which is a standard warranty length compared to the rest of the bed-in-a-box mattress industry. For our full breakdown, see the Purple mattress warranty.
Casper mattresses ship for free to the 48 contiguous U.S. and parts of Canada, with shipping to Alaska and Hawaii available for an additional fee.
The Casper return policy is very similar to Purple’s. Casper beds come with a risk-free 100-night sleep trial and a slightly longer 30-day waiting period. You may return your mattress during this time for a full refund. The Casper Original mattress also comes with an industry-standard 10-year warranty: the same warranty length that Purple offers.

While the Casper and Purple are both popular bed-in-a-box mattresses, the Purple mattress is better for people who sleep hot and those with joint pain. The Casper mattress’s Zoned Support memory foam makes it a superior choice for stomach sleepers and people who like the hugging feel of an all-foam mattress. Both beds work for back sleepers and side sleepers under 230 lbs.
