Need Help Deciding?

For most sleepers, we recommend the Allswell Hybrid over the Casper The One. It scores higher in cooling, edge support, price-to-value and delivers stronger overall value. The Casper The One is the better choice only if you have a strong preference for that brand's specific feel or design.

Allswell Hybrid vs Casper The One: What Actually Differs

The Allswell Hybrid is a hybrid 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 10" for the Allswell Hybrid — a 1.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. Both sit at roughly 6/10 on the firmness scale — a medium-firm feel — so neither one is the answer if you need a dramatically different support level. The single largest performance gap is in motion isolation: the Casper The One rates noticeably higher than the Allswell Hybrid, which is the deciding factor if that dimension is high on your list. On a Queen, the Allswell Hybrid runs $299 versus $799 for the Casper The One — roughly $500 (63%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.

Which Is Better For Your Sleep Style?

Side sleepers
Casper The One

Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.

Back sleepers
Either works

Both fall in the medium-firm zone back sleepers prefer (6/10 vs 6/10) — either works.

Stomach sleepers
Either works

Effectively the same firmness (6/10 vs 6/10). Stomach sleepers generally want 7+/10 — neither is ideal if both rate lower.

Hot sleepers
Spec not available

Cooling rating not available for one or both mattresses — spec not available.

Heavier sleepers (230+ lb)
Casper The One

better long-term durability — the two specs heavier sleepers should weight most.

Lighter sleepers (under 150 lb)
Casper The One

Same firmness on both, but stronger pressure relief — lighter sleepers don't sink in as much and benefit from the more contouring of the two.

Couples / light sleepers
Casper The One

Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.
