One of the biggest names in bed-in-a-box mattress brands is Casper. This year, it’s done a full redesign with five new beds. The new Casper One is intended to be its entry-level foam mattress in the same spirit as previous iterations of the Casper Original and The Casper mattress. First impressions of the Casper One Foam mattress
I was excited to unbox all of the new Casper beds, because we’ve always regarded these popular beds highly. We received all of the new beds in our office on the same day, and it was a very cold day outside when the boxes arrived. Sometimes, we’ll wait a day or two before unboxing a new bed, but we unboxed these mattresses right off the truck.
I mention the weather because the temperature can have an impact on the rigidity of foams, and when we removed the Casper One from the plastic, it was one of the most misshapen-looking beds I have ever seen. I had a good laugh about it because it looked funny, and we knew it was not due to some defect in the mattress. Beds often look misshapen right out of the box, but this one was pretty extreme.
It took about a full day for the bed to fully inflate and get into its normal shape. I was immediately surprised when trying the Casper One for the first time because it was much firmer than I’d expected. Previous models of Casper foam beds were usually around a medium on our firmness scale, and it was clear that Casper was going in an entirely different direction with the Casper One.Video: Casper One Foam review video
Watch me review the Casper One Foam mattress in this video. One Foam construction and feel
The Casper One Foam mattress has a classic three-layer all-foam design, which is what we saw on the old models of Casper and beds from many other brands, including Nectar, Bear, Leesa and Nolah.
The bottommost layer is a 7-inch layer of Casper Core support foam, which is the main support layer of the Casper One. This is the only mattress out of the five new beds from Casper that features a foam support layer instead of pocketed coils. I generally prefer coil beds for the added bouncy feel, and coils are usually better for support and durability throughout the life of the mattress, but there are plenty of sleepers who prefer foam beds because foam has better motion isolation, is easier to move and is usually more affordable.
Above the support foam is a 2-inch layer of Align memory foam, and then right above that is another 2-inch layer of Breathe Flex foam. The memory foam layer is classically dense, as you’d expect from memory foam, and the top layer is a more neutral, responsive foam.
This combination of foams adds up to give the Casper One Foam a somewhat unique feel. The memory foam layer gives the bed a dense feel that is balanced out by the more responsive layer above it. I think the bed has a similar dense type of feel, like a memory foam, but without the sink in quality.
Overall, I’d describe it as having a firm, dense foam feel, which isn’t something I’ve observed very often. It’s quite a departure from the old Casper Original, which had a soft, neutral feel that I would describe as more accommodating to more sleepers in comparison to the Casper One.Casper One Foam firmness and sleeper types
The Casper One Foam is significantly more firm than the previous Casper model. The old Casper Original was rated at a medium, but the Casper One is a medium-firm to firm on our scale. It’s closer to a medium-firm than a true firm, but it’s definitely somewhere in between.
Casper describes the Casper One as a firm option that is ideal for back and stomach sleepers, and I absolutely agree.
