The single biggest reason to consider this mattress is the layered foam design: a 2.5-in ocean-blue cooling gel memory foam over 9.5-in high-rebound support foam that aims to pull heat away while still offering body-contouring and spinal alignment. It also arrives vacuum packed and expands within 48 hours, with an OEKO-TEX certified cover and CertiPUR-US certified foams.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling gel layer:\u003c\/strong\u003e The 2.5-in ocean-blue cooling gel composition draws heat away from the body so sleepers stay cooler through the night.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody-contouring memory foam:\u003c\/strong\u003e The memory foam layer molds to curves and reduces pressure points for more restful sleep without uncomfortable sinking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-rebound support foam:\u003c\/strong\u003e The 9.5-in high-density support foam provides lift and durable support while expanding to full shape within 48 hours of unpacking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedium-firm feel:\u003c\/strong\u003e The combination of layers creates a medium-firm profile that balances contouring and support for many sleeping positions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertified materials:\u003c\/strong\u003e Foams carry CertiPUR-US certification and the knit cover is OEKO-TEX certified for safer indoor use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiberglass free and washable cover:\u003c\/strong\u003e The soft, breathable jacquard cover is skin-friendly, washable, and guarantees a fiberglass-free interior.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe mattress works well for back and combination sleepers who want a medium-firm feel with pressure relief and cooler nights thanks to the gel memory layer.
