Definition of High-Resilience Foam (HR Foam)

Meaning of the Term as it Pertains to Mattresses

What is High-Resilience Foam?

The highest grade of polyurethane foam, HR foam is extremely responsive and offers the same level of support as high-density foam. With a structure of randomly arranged open cells, high-resilience foam allows for extreme elasticity along with offering sturdy support. HR foam also maintains its responsive properties longer than regular foam and offers showroom-level comfort after years of use. High-resilience foam snaps back to its original shape immediately after compression, while regular foam tends to lag and take a few moments to reshape.

A less common foam type, HR foam is more expensive to produce than regular and high-density foam. In general, high-resilience foam mattresses are more expensive than innerspring mattresses but generally cheaper than latex mattresses. A dense foam type, high-resilience foam tends to weigh about 2.5 lbs. per cubic foot.
