Need Help Deciding?
For most sleepers, we recommend the WinkBed GravityLux over the Keetsa Supreme. It scores higher in cooling, motion isolation, pressure relief and offers strong overall value at $1,799 (vs $1,990). The Keetsa Supreme is the better choice only if you have a strong preference for that brand's specific feel or design.
Keetsa Supreme vs WinkBed GravityLux: What Actually Differs
Both the Keetsa Supreme and WinkBed GravityLux are foam mattresses, so the real differences come down to firmness tuning, performance ratings, and price rather than construction type. The WinkBed GravityLux stands 13.5" tall versus 12" for the Keetsa Supreme — a 1.5" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The WinkBed GravityLux is the firmer of the two at 5/10 (medium), and the Keetsa Supreme sits at 4/10 (medium-soft) — a meaningful enough gap that sleeper position and weight should drive the choice. On a Queen, the WinkBed GravityLux runs $1,799 versus $1,990 for the Keetsa Supreme — roughly $191 (10%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about. Trial periods aren't symmetrical either: the WinkBed GravityLux ships with a 120-night sleep trial versus 90 nights for the Keetsa Supreme, giving you a longer in-home runway to send it back if the feel doesn't land.

Firmness of 5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 4/10).
Firmer at 5/10 vs 4/10 — 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 4/10 vs 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.
