Casper vs Purple: Honest Comparison for 2026
We tested both flagship mattresses hands-on. Here’s the unfiltered head-to-head — feel, cooling, motion, and value.
While the Purple Mattress offers game-changing cooling and pressure relief, its unique feel isn’t for everyone. The Casper Original is the safer bet and our overall winner, delivering a balanced, accommodating foam feel with zoned support that suits the widest range of sleepers right out of the box.
Quick verdict by sleep style
Casper’s zoned support offers slightly better spinal alignment for a wider range of body types, though Purple provides elite pressure relief on the hips and shoulders.
Both mattresses excel here, providing a fantastic blend of contouring and support to keep the spine comfortably aligned.
Neither is ideal, but Purple‘s slightly firmer feel offers a small advantage in preventing excessive hip sinkage compared to the Casper Original.
This is a blowout win for Purple; its open GelFlex Grid provides superior airflow that foam simply cannot match.
It’s a tie, as both beds masterfully absorb motion, but both also suffer from mediocre edge support, slightly reducing the usable surface area.
Neither 100% foam/grid model is a great choice; sleepers over 230 lbs will find better durability and support in a hybrid mattress.
How Casper Original actually feels
The Casper Original delivers what we call a “balanced foam feel.” It doesn’t have the slow, deep sink of traditional memory foam, nor the instant bounce of latex. Instead, it’s a gentle, responsive contour that makes it incredibly easy to move around on. On a 10-point firmness scale, we rate it a solid 6/10, a true medium that hits the sweet spot for combination sleepers.
The key feature is its Zoned Support™, which feels noticeably firmer under your hips and torso, preventing that dreaded V-shape and promoting spinal alignment. While it isolates motion exceptionally well—you won’t feel your partner tossing and turning—the edge support is merely average. You’ll notice significant compression when sitting on the edge, a common trade-off for an all-foam bed-in-a-box.
It’s a crowd-pleasing feel that’s comfortable and familiar from the first night.
How Purple Mattress (Original) actually feels
Sleeping on the Purple Mattress is unlike any other bed. The top GelFlex™ Grid creates a bizarre and wonderful sensation of floating. It’s simultaneously soft and firm; the grid columns collapse under your sharpest pressure points like shoulders and hips, while the surrounding grid stays upright to support you.
We rate its firmness slightly higher than the Casper, around a 6.5/10. The feel is exceptionally responsive and bouncy, making it effortless to change positions. There’s no “stuck” feeling whatsoever. The most immediate sensation, however, is the coolness. You can feel the air moving through the grid. Motion isolation is surprisingly good, but its biggest weakness is edge support, which is decidedly poor.
Sitting on the edge feels unstable, and sleepers who hug the perimeter might feel a roll-off sensation. It’s a divisive feel you’ll either love or hate.
What’s inside each one
Casper Original construction
The 11-inch Casper Original is built with three layers of all-polyfoam construction. The top layer is Casper’s AirScape™ foam, a perforated, breathable polyfoam designed for a C- a bit of cooling and responsiveness. Below that is the key transition layer: a memory foam layer with Zoned Support™. This layer is firmer in the center third to provide more support for the hips and lower back, and softer at the head and shoulders for pressure relief.
The base is a thick, durable layer of high-density polyfoam that provides the foundational support for the entire mattress.
Purple Mattress (Original) construction
The 9.25-inch Purple Mattress has a simpler, yet more innovative, three-layer design. The star of the show is the top 2-inch layer of the GelFlex™ Grid, a hyper-elastic polymer molded into an open-celled grid structure. This is what provides the unique feel and incredible airflow.
Beneath the grid is a 3.5-inch transition layer of medium-soft polyfoam to cushion you from the firm base. The foundation is a 4-inch layer of high-density polyfoam, providing stability and durability. The entire mattress is wrapped in a soft, stretchy SoftFlex cover designed to move with the grid.

Frequently asked questions
Which is better for side sleepers, Casper or Purple?
It’s a close call. Casper’s Zoned Support offers targeted support that many side sleepers love for spinal alignment. However, Purple‘s grid is phenomenal at relieving pressure on the hips and shoulders, which can be a game-changer for those with joint pain.
Which mattress sleeps cooler?
Purple, and it’s not even close. The GelFlex Grid’s open channel design allows for significant airflow, making it one of the coolest-sleeping mattresses on the market. Casper’s perforated foam helps, but it is still a block of foam and will retain more heat.
Are Casper and Purple good for back pain?
Both can be excellent for back pain, but for different reasons. Casper’s Zoned Support™ adds firmness under the lumbar region to prevent sagging and keep the spine aligned. Purple’s grid dynamically adapts, collapsing under pressure points while supporting the rest of the back, which many find alleviates pain.
What’s the price difference?
Casper and Purple pricing moves with promotions. Check the current Queen price for each brand before deciding which is the better value.
Do they offer a sleep trial?
Both brands publish home-trial and return policies. Check the current terms, fees, and eligibility rules before ordering because they can change.
