Both the Zinus and Casper mattresses are made from layers of CertiPUR-US certified memory foam and polyfoam. Thanks to variation in their unique foam layers, these beds boast different firmnesses and sleeping experiences.
The Casper is a 3-layer mattress with a medium-firm feel. Its polyfoam top layer delivers immediate cushion while its transition layer of zoned memory foam provides give and support exactly where you need it. Combined, these layers create a balanced foam feel, so you won’t feel stuck like you may on the Zinus mattress.
The Zinus Cooling Gel Memory Foam mattress comes in four thicknesses: 8”, 10”, 12”, and 14”. The 8” is a medium firmness, the 10” and 12” a medium-soft, and the 14” a plush bed. While Casper has a polyfoam top layer and memory foam second layer, Zinus’s mattress has the opposite. This, combined with the lack of zoning, makes the Zinus mattress have a more distinct memory foam hugging feel.
We tested both of these mattresses at the Mattress Advisor lab. Take a look at our side-by-side comparison to see how they performed.

Sturdy edges are an essential feature of a mattress for many couples. When you share the bed, you tend to spread out in order to stake out your own space and sleep more peacefully. But not all mattresses have edges worthy of a snuggle.
In our edge support tests, the Casper mattress earned one of the highest marks for any all-foam mattress—and Zinus earned one of the lowest. If you share your mattress and happen to cozy up to the edges, we recommend going with Casper over Zinus.
Motion transfer is the other of our tests that tends to be the most important for couples and those who share their mattress with kids or pets. When your bed partner gets in or out of bed or moves around when you’re sleeping, motion transfer can wake you up, leading to poor sleep quality.
Zinus did an exceptional job absorbing motion and limiting motion transfer, while Casper did slightly less well. While both earned scores high enough that we would suggest them for couples, extra-light sleepers may find that they sleep more soundly on the Zinus.
Body alignment is one of the most influential factors that determines how your body feels come morning. This is true for side, stomach, and back sleepers. When we examined the spinal support offered by these two mattresses, they both earned higher scores than the average bed. However, Casper’s 9.5/10 makes it an excellent choice for people with back pain or body aches.
If you’re on a tight budget, the Zinus Gel Memory Foam bed is one of the best mattresses that you’ll find for under $500. But if you have a bit more to spend, we recommend the Casper thanks to it outperforming the Zinus in most of our in-house tests.
