We use the highest quality CertiPUR™ foam in our mattresses. Our foam is "Open Cell" and chemical free, which means it never off gasses and has No Chemical Fire Retardents! Our fabric covers rely on silica embedded in the fibers(per CA standards).
We offer 2.6lb High Resiliency foam mattresses in Twin, Twin XL, Full/Double, Queen, Split Queen, Split King and Split California King for our beds, daybeds and analytic couches.
Polyurethane foam is specified with four numbers (i.e. 2635); the first two (26xx) refer to the foam density, and the second two (xx35) refer to the foam firmness. Each measurement is independent of the other. Firmness does not affect density, and density does not affect firmness. Foam with a 2635 specification refers to a 2.6 lb High Resiliency foam with a 35 ILD.
Indentation Load Deflection or ILD (also known as IFD, Indentation Force Deflection) is a measurement of polyurethane foam firmness. It refers to the amount of force, in pounds, required to indent 4 inches of foam 25%. Higher the ILD, firmer the foam. Polyurethane foams come in a wide range of ILDs, most commonly 23 ILD or 27 ILD (for upholstered seats, couch cushions and soft mattresses) to 35 ILD or 45 ILD (for firmer seats, cushions or mattresses), but are available in ILDs both higher and lower than that.
In contrast, premium foam mattresses appear a much better value. Bedworks' High Resiliency Foam Mattresses carry 10-year warranties. They cost less, are healthier, slimmer, more attractive and easier to move.
Foam density is also a measure of its quality. Lower quality (and therefore less expensive) foam mattresses use a lower density foam, which does not last nearly as long as High Resiliency foam. Don't be fooled. Ask about the density to get a better idea of its quality. We use 2.6lb High Resiliency foam in our hand-layered bed mattresses.
