The Cocoon by Sealy Chill Hybrid is the better choice only if you have a strong preference for that brand's specific feel or design.
Casper The One vs Cocoon by Sealy Chill Hybrid: What Actually Differs
The Casper The One is a memory foam build, while the Cocoon by Sealy Chill Hybrid is a hybrid — that single difference drives most of the cooling, motion, and feel decisions below. The Cocoon by Sealy Chill Hybrid stands 12" tall versus 11" for the Casper The One — a 1.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Casper The One is the firmer of the two at 6.5/10 (medium-firm), and the Cocoon by Sealy Chill Hybrid sits at 5.5/10 (medium) — a meaningful enough gap that sleeper position and weight should drive the choice. Queen pricing lands within $53 of each other ($799 vs $746), so price is essentially neutral — pick on feel and features rather than budget.

Both fall in the medium-firm zone back sleepers prefer (6.5/10 vs 5.5/10) — either works.
Firmer at 6.5/10 vs 5.5/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.
Cooling rating not available for one or both mattresses — spec not available.
Durability and edge-support ratings not available — spec not available.
Softer at 5.5/10 vs 6.5/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Motion-isolation data not available for one or both mattresses — spec not available.
