For most sleepers, we recommend the Casper The One over the Purple The Purple Mattress. It scores higher in cooling, motion isolation, pressure relief and offers strong overall value at $799 (vs $1,399). The Purple The Purple Mattress is the better choice only if you have a strong preference for that brand's specific feel or design.
Purple The Purple Mattress vs Casper The One: What Actually Differs
The Purple The Purple Mattress is a gel grid build, while the Casper The One is a memory foam — that single difference drives most of the cooling, motion, and feel decisions below. The Casper The One stands 11" tall versus 9.25" for the Purple The Purple Mattress — a 1.8" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. Both sit at roughly 6.5/10 on the firmness scale — a medium-firm feel — so neither one is the answer if you need a dramatically different support level. On a Queen, the Casper The One runs $799 versus $1,399 for the Purple The Purple Mattress — roughly $600 (43%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.
