Rebond is our most durable and firmest 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. For cushions it should be used with V44 or V54 foam glued on top to mitigate its firmness. For mattresses for very heavy individuals it should be used under 4" of memory foam. Since this foam is so dense it has very little give. (Density: 8 lbs/ft³) See our Foam Glossary to learn more.
