At about a 6 out of 10 it holds your spine level and keeps your hips from dropping, while the named Apex Top, three added inches of GelFeel Firm HD memory foam over a high-density foam encasement, keeps the perimeter solid so the full width sleeps usable and the side holds when you sit. With 4K Micro Coils and Self-Response latex layered over a firm-tuned Triple-Stranded Pocketed Coil core, this is firm done with the most hardware Black puts in a bed.\u003c\/p\u003e\n\u003ch2\u003eFirm support that still contours\u003c\/h2\u003e\n\u003cp\u003eThis is a firm bed, not a hard one. Beautyrest tunes the Firm Apex Top as a deeply contouring, responsive surface with firmer, conforming support: a 6 out of 10 that lands on the supportive side of center, so your hips stay up and your spine runs straight while the surface still cradles. The contouring is the part inexpensive firm beds get wrong. ContourFit nestles you into FORM HD Material, a high-density foam that cradles your curves, while Self-Response latex underneath answers each movement instead of sagging. Firm here means supported, not stiff.\u003c\/p\u003e\n\u003ch2\u003eWhat the Apex Top actually does\u003c\/h2\u003e\n\u003cp\u003eMost firm mattresses give you a strong middle and an edge that rolls away the moment you sit. The Apex Top fixes that. It stacks three additional inches of GelFeel Firm HD memory foam across the surface and wraps the whole bed in a high-density foam encasement, so the edge stays firm and the sleeping area runs corner to corner. Sit on the side to put on your shoes and it holds; roll to the edge in your sleep and you do not feel the drop-off. On a bed shared by two, that reclaimed perimeter is real sleeping space, not a soft border you both avoid.\u003c\/p\u003e\n\u003ch2\u003eUnderneath: the coils and the cooling\u003c\/h2\u003e\n\u003cp\u003eSupport starts with the 4K Micro Coils, the highest coil count Black builds into a bed, sitting over a firm-tuned Triple-Stranded Pocketed Coil core. Instead of one broad push back, the surface answers in small increments, so support tracks your back and hips closely. The pocketed coils also move on their own, so a restless partner barely registers on your side of the bed.\u003c\/p\u003e\n\u003cp\u003eHeat is managed at the surface and in the build. The cool-to-the-touch Sleep Climate Surface pairs with Micro Diamond memory foam, infused with diamond particles to pull warmth off the body, and as a hybrid the coils breathe far more than any all-foam bed. A cool cover helps most in the first minutes, but a firm hybrid surface breathes better than a soft one, so this build sits on the right side of that trade.\u003c\/p\u003e\n\u003ch2\u003eLiving with it\u003c\/h2\u003e\n\u003cp\u003eAt 16.75 inches this is a substantial flagship hybrid, so measure your frame and buy deep-pocket sheets before it arrives. It pairs with an adjustable base, carries a 10-year limited manufacturer's warranty, and is built with CertiPUR-US certified foams.\u003c\/p\u003e\n\u003ch2\u003eWho it suits, and who it does not\u003c\/h2\u003e\n\u003cp\u003eThis is a back and stomach sleeper's bed first.
