The mattress combines layers of high-density support foam, gel memory foam and power packed wrapped coils to deliver steady support night after night. It arrives compressed in a box and expands in about 48 hours, and it is made with CertiPUR-US certified foam and a 4-way stretch knit cover for a balanced mix of firmness, pressure relief and breathability.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFirm comfort:\u003c\/strong\u003e High-density foam forms the mattress core to deliver the firm support that keeps the spine aligned for many back and stomach sleepers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure relief:\u003c\/strong\u003e A layer of gel memory foam contours at key pressure points to reduce shoulder and hip soreness without excessive sink.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHybrid support:\u003c\/strong\u003e Rows of power packed wrapped coils give responsive support and help maintain structure across the sleep surface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling design:\u003c\/strong\u003e Gel-infused memory foam and a 4-way stretch knit cover work together to disperse heat for a cooler night.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConvenient delivery:\u003c\/strong\u003e The mattress ships compressed in a box, unrolls quickly and reaches full size in about 48 hours for easy setup.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertified materials:\u003c\/strong\u003e Foam components meet CertiPUR-US standards and the mattress carries a 10 year limited warranty.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe mattress is best for couples and individuals who prefer a noticeably firm feel and need steady support from edge-to-edge; the wrapped coils add responsiveness for combination sleepers who change positions.
