Foam Mattress

This very durable foam is soft and comfortable in seat down envelopes. When used as a back cushion foam it feels firmer. (Density: 2.6 lbs/ft³, ILD: 24.)

We recommend this very high quality foam for any cushion or mattress. V34 is not recommended for seat cushions 3" (8 cm) or thinner since you will bottom out—use the firmer foams. We strongly recommend you buy a custom cover to protect any foam of this quality from rips and stains. It is a very good foam. Engineered using a high resilience (HR) cell structure. (Density: 2.6 lbs/ft³, ILD: 34.)

This is one of the best pieces of poly urethane foam and will give you many years of support. It is recommended for seat cushions or mattresses. This foam is too firm for back cushions.

EverFlex™ V54 is a high quality firm grade of foam. This foam is one of the best qualities. It is great for a seat cushion or firm mattress, but too firm for back cushions. If your weight is 200–230 pounds (91–104 kg), then this foam is appropriate for a firm cushion 5" (13 cm) or thicker. We strongly recommend you buy a custom cover to protect any foam of this quality from rips and stains. Engineered using a high resilience (HR) cell structure. (Density: 2.9 lbs/ft³, ILD: 54.)

Rebond is our most durable foam. In most applications it won’t soften or dip with time. This very firm, high-density foam is perfect for applications that get a lot of use and compression, such as motorcycle seats, gym equipment, and high-use benches. It should be used with V54 foam glued on top for cushions to mitigate its firmness, or be used with 4" memory foam for mattresses for very heavy individuals. Thicker applications, such as a 4"-thick cushion, should be made from 2" of V54 glued on top of 2" of Rebond foam. Since this foam is so dense it has very little give. (Density: 8 lbs/ft³.)

This is a good quality foam. We recommend it for mattresses, window seats, and seat cushions. (Density: 2.6 lbs/ft³, ILD: 30.)

This foam is an inexpensive grade and good for any application in which you want something a little on the soft side. We recommend it for back cushions on a couch, guest beds, window seats, or for really thick seat cushions. It is not recommended for seat cushions 3" (8 cm) or thinner since you will bottom out—use the DuraFlex™ foam or firmer foams. (Density: 1.8 lbs/ft³, ILD: 18.)

A medium foam. It is an inexpensive grade and good for any application. We recommend it for cushions on a couch, guest beds, window seats, or for really thick seat cushions. This quality is commonly found in all new furniture. It will soften with use so perhaps start with the C55 foam. EconoFlex™ C33 is not recommended for seat cushions 2" (5 cm) or thinner since you will bottom out—use the DuraFlex™ foam or firmer foams. (Density: 1.8 lbs/ft³, ILD: 36.)

EconoFlex™ C55 is a firm to very firm foam. It is also inexpensive. It is fine for a guest bed, window seat, or firm seat cushion in a sofa that is not used regularly. Regular use will break down this foam and its firmness will feel more “medium” with time. This foam is too firm for back cushions. It is great for 1", 2", and 3" (3–8 cm) thick applications since it won’t easily bottom out. (Density: 1.8 lbs/ft³, ILD: 55.)

A lightweight foam perfect for applications that will not be compressed very often. This inexpensive foam will soften and may deform from being compression packaged when shipped. It takes 1–2 weeks to fully uncompress. (Density: 1.2 lbs/ft³, ILD: 36.)
