The mattress ships compressed in a box and expands to a full 84in by 72in by 12in, so it is convenient to move into a bedroom without heavy lifting. What stands out is the combination of cooling gel memory foam and hundreds of pocketed springs that deliver targeted support while reducing motion transfer, making it a sensible choice for couples and people with back discomfort.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreathable knit cover:\u003c\/strong\u003e The hypoallergenic knitted fabric is breathable and gentle on skin, helping sleepers stay cooler through the night.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling gel memory foam:\u003c\/strong\u003e Gel-infused foam conforms to body shape to relieve pressure and reduce tossing for more restorative sleep.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndividually pocketed springs:\u003c\/strong\u003e Hundreds of coils work with the foam to distribute weight evenly and provide zoned support from head to toe.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpgraded edge support:\u003c\/strong\u003e Stronger outer coils prevent edge collapse so the full surface feels usable and stable when sitting or sleeping near the edge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertiPUR-US certified foam:\u003c\/strong\u003e The memory foam is free of fiberglass and other harmful substances, offering a safer sleep environment for sensitive users.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMattress in a box delivery:\u003c\/strong\u003e Vacuum-packed and compressed for easy shipping, the mattress expands to full size within 24-72 hours after unboxing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis mattress is well suited to couples and back sleepers who prefer a medium firm surface that balances contouring with support.
