WinkBeds GravityLux

Sources & review notes

• Exact model — GravityLux — Medium option. Checked 2026-10-20. WinkBeds’ all-foam model, sold in Soft, Medium, and Firm. WinkBeds identifies Medium as the most popular, and the fit table on this page is Medium-specific — the independent lab publishes a separate table for each option and they differ sharply. Not to be confused with The WinkBed or the EcoCloud, both of which are coil hybrids.
• Type — All-foam — no coils. Checked 2026-10-20. A TENCEL cover quilted with gel-infused foam over patented AirCell memory foam, a zoned Progression Foam transition layer, and an ATLAS Core base at 1.8 lb density. AirCell is a non-visco memory foam built around air capsules, which is why it behaves differently from conventional memory foam.
• Firmness — Medium — 5/10 measured. Checked 2026-10-20. The middle of three options, measured at 5 of 10. Soft measures 4 and Firm measures 7, and the fit results diverge dramatically between them: Firm is the only option that suits stomach sleepers, while Soft is the only one that strongly suits lighter side sleepers.
• Height — 11 inches. Checked 2026-10-20. Confirmed identically by WinkBeds and by independent measurement, and consistent across all three firmness options.
• Price — Check current price — $1,799 queen on sale, $2,570 list. Checked 2026-10-20. Expensive for an all-foam mattress, and priced level with the coil-hybrid WinkBed Original on the checked date. WinkBeds discounts periodically, so the sale figure is closer to the effective everyday price; the independent reviewer recorded a $1,427–$2,856 range across sizes.
• Trial — 120-night trial, 30-night minimum. Checked 2026-10-20. You must keep the mattress at least 30 nights before requesting a return or exchange. That matters more than usual here, because choosing the wrong firmness of three is the most likely way to be unhappy with this bed.
• Delivery — Free shipping, about one week. Checked 2026-10-20. Ships via ground courier in roughly a week. Free to the contiguous US.
• Returns — Free returns; firmness exchanges cost $49. Checked 2026-10-20. Returns are free with scheduled pickup and a refund within about five days. Exchanging for a different firmness carries a $49 fee — worth knowing given how much the three options differ.
• Warranty — Lifetime warranty with full replacement. Checked 2026-10-20. Covers defects in workmanship and materials, and indentations exceeding 1.5 inches. On an all-foam mattress rated 6.5/10 for materials durability, that 1.5-inch threshold is the number that matters most.
• Firmness — Medium (5/10). Measured data. The middle of three options at a true 5 of 10. Because the three options differ so much in fit, the firmness you choose matters more on this mattress than on almost any other reviewed here.
• Pressure relief — 8 / 10 — rated across all three firmness options. Measured data. The strongest attribute. Note the independent lab rates these seven metrics for the GravityLux as a model rather than per firmness, so read this as a family-level result; only the fit table below is Medium-specific.
• Cooling — 7.5 / 10 — rated across all three firmness options. Measured data. Reasonable for an all-foam bed with no coil layer to move air. The gel-infused quilted cover and the air-capsule structure of AirCell do most of the work.
• Motion isolation — 7.5 / 10 — rated across all three firmness options. Measured data. Good but not exceptional, which is mildly surprising for an all-foam build. AirCell’s faster recovery means it absorbs slightly less movement than traditional memory foam would.
• Response / bounce — 7.5 / 10 — rated across all three firmness options. Measured data. Better than most all-foam mattresses manage. The air-capsule structure springs back rather than holding a contour, so repositioning is easier than on a conventional memory-foam bed.
• Edge support — 7.5 / 10 — rated across all three firmness options. Measured data. Respectable for a foam mattress with no reinforced perimeter, helped by the dense ATLAS Core base resisting compression at the sides.
