The full review
The Casper Original Mattress remains the product that put Casper on the map, a foam mattress engineered to solve the one problem side, back, and stomach sleepers all complain about: pressure buildup at the hips and shoulders. It uses a layered foam construction, with a breathable open-cell top layer designed to keep air moving so the bed doesn't trap body heat the way traditional memory foam often does. Beneath that sits a transitional support layer and a durable base foam that keeps the mattress from feeling like it's swallowing you whole, giving it what Casper calls "zoned support," with slightly firmer foam under the lower back and softer foam for shoulders. The result is a medium-firm feel that aims to work for a broad range of body types and sleep positions rather than catering to just one.
What makes the Original stand out in the crowded bed-in-a-box category is its balance. It isn't a plush pillow-top that sinks endlessly, nor is it a rock-hard slab marketed as "supportive." Instead, it lands in that middle ground that Casper has spent years refining, offering just enough contouring to relieve pressure points without losing the responsiveness needed for easy movement during the night. Couples often note that the foam layers do a reasonable job of isolating motion, so a restless partner is less likely to disturb the other. The mattress ships compressed in a box, expands within hours, and is sized to fit standard bed frames from twin all the way up to California king, making it a straightforward swap for anyone upgrading from an old innerspring set.
Beyond the physical build, the Original is backed by Casper's standard sleep trial and warranty, giving buyers real time to adjust before committing long term, since foam mattresses often require a short break-in period as the material softens and the sleeper's body adapts to it. The breathable cover is soft against the skin and designed to complement the foam's cooling properties rather than trap heat against the body. For anyone furnishing a bedroom focused on genuine rest and recovery, the Casper Original serves as a dependable, well-tested foundation, less about flashy extras and more about consistent, night-after-night comfort that holds up over years of use.

Specifications
What owners say
Switched from an old spring mattress and this has been a game changer. Sleeps cool and my back pain has improved significantly. Highly recommend for combo sleepers.
Comfortable bed with good support, but I was hoping for more of a plush feel. Still, no complaints about temperature or motion transfer with my partner.
Setup was easy and the trial period gave me peace of mind. It's not as luxurious as premium brands but performs very well for everyday sleep needs.
The mattress is fine overall, but I noticed some sinking near the edges when sitting. Otherwise support and cooling are good.
