It runs neck and neck with the standard Series Three Firm, so the honest move is to lie on both. Either way you get genuinely firm support for back and stomach sleepers, refined by responsive latex and kept cool by the Series Three layer.\u003c\/p\u003e\n\u003ch2\u003eA firm bed that does not sleep hard\u003c\/h2\u003e\n\u003cp\u003eMost firm mattresses force a trade: you get the support, you give up the surface. This one keeps the 7\/10 backbone and softens only the top inch you actually touch, so hips lift and the spine stays level without the board-hard feel.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eA firm 7\/10 feel.\u003c\/strong\u003e Hips lifted, spine level: supportive and on-top, without extra-firm hardness.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-Response™ Latex + SurfaceTouch™ Gel.\u003c\/strong\u003e Responsive latex and surface gel refine the firm surface without softening the support underneath.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicro Diamond™ cooling + cool-to-the-touch cover.\u003c\/strong\u003e The Series Three cooling, which matters most on a firm surface you feel directly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriple-Stranded Pocketed Coil® core, 15.25 inches.\u003c\/strong\u003e Firm support and real motion separation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium Black build, CertiPUR-US foams, 10-year limited warranty.\u003c\/strong\u003e Refined firm support meant to hold its shape.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSeries Three is the Series Two build plus responsive pressure relief and added support, so on a firm surface the latex push-back and the Micro Diamond™ cooling count for more here than on a plush model.\u003c\/p\u003e\n\u003ch2\u003eWhat you notice the first few minutes lying on it\u003c\/h2\u003e\n\u003cp\u003eOn your back, your hips come up to meet your shoulders and your lower back is supported instead of dropping into a hammock. On your stomach, the firm surface holds your midsection level. Press a hand in and the latex returns it quickly rather than letting you sink, and if you run warm, the cover stays cool where a softer bed builds up heat.\u003c\/p\u003e\n\u003ch2\u003eWho it is not for, and the Mattress Overstock team would rather say so now\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide sleepers.\u003c\/strong\u003e A 7\/10 firm will press on your shoulder and hip; a medium or plush Black is the better fit, because side sleeping needs the surface to give at those pressure points.
