The mattress combines 2.5 in of gel-infused memory foam over 9.5 in of high-density base foam to deliver contouring support that reduces pressure points while the gel particles help dissipate heat. It ships compressed in a box and is best for shoppers who prioritize comfort, value, and a universally supportive medium-firm feel.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGel-infused memory foam:\u003c\/strong\u003e The top 2.5 in layer uses gel particles to help manage temperature and create a more comfortable sleeping surface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupport core:\u003c\/strong\u003e The 9.5 in high-density base foam provides steady support and helps the mattress maintain shape for back alignment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedium-firm feel:\u003c\/strong\u003e Multiple layers are tuned for a balance of contouring pressure relief and enough firmness to suit many sleep positions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreathable cover:\u003c\/strong\u003e The soft knitted fabric cover wicks moisture and adds a slightly cooler, drier sleep surface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBed-in-a-box convenience:\u003c\/strong\u003e The mattress ships compressed and rolls out at home, making setup and transport straightforward.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis mattress is a good match for couples, back sleepers, and combination sleepers who want moderate contouring without sinking too deeply; the medium-firm feel aims to serve a wide range of body types.
