Firm Extra Firm Chirofoam® Performance Mattresses and Accessories

How to Choose a Chirofoam Mattress

Chirofoam sits at the firmer end of the comfort scale, and that is the first thing to settle before you compare models. The range covers two builds. On the hybrids the support core is a foam-encased pocket coil: individually wrapped springs of heat-tempered drawn spring steel, ringed by a perimeter wall of firm polyurethane foam. Each coil compresses on its own, so the surface follows the curve of your spine instead of levelling it, while the encasement braces the sides when you sit on the edge of the bed. The all-foam models reach a similar firm feel over a polyurethane core, with no springs in them at all. Above either core, firm comfort layers hold the pelvis near the surface rather than letting it drop below the ribs.

Firmness is a fit question, not a quality ranking. Back sleepers generally do best on medium to firm, enough support to fill the lumbar curve without flattening it. Stomach sleepers want the firm end, which keeps the pelvis from dropping below the ribs. Extra firm goes further again, and belongs to stomach sleepers and to heavier bodies, which compress any comfort layer further and read the same mattress as softer. Side sleepers run the other way: the shoulder and hip need somewhere to go, so a very firm surface can leave the spine bowed, and a medium or plush feel is the usual fit. If you want a firm core under a softer surface, a mattress topper is the standard route. Persistent or severe pain is a question for a clinician, not a mattress.
