High-density foams are foam with high weight per cubic foot and therefore have a strong cell structure, which makes the material highly durable. This does not have an effect on how soft or firm the mattress is. Density only indicates quality and durability, not your comfort level.

What's the difference between high density foam and regular foam?

Foams with a high density will generally feel more firm, and can withstand more pressure. Conversely, low-density foams will feel softer, but cannot withstand excessive pressure or weight. When it comes to memory foam in particular, higher-density foams recover more slowly after pressure is applied to it.

What is high density foam made from?

High density foam is made of a blend of polyurethane and has a tendency to off-gas. If you are susceptible to lung issues, please do additional research on the quality of foams before purchasing. Pros: Structural firm foam used by many mattresses to provide foundation and shape.
