foam for mattresses

Choosing the right foam for mattresses makes the difference between restful sleep and a bed that sags within a season. Whether you're building a custom daybed, replacing a worn RV cushion, or adding a plush topper, the foam inside sets the tone for comfort and longevity.

What to Look for in Mattress Foam

Not all foam is created equal. A few key qualities help you match foam to the way you sleep.

Density

High density foam holds its shape longer and resists body impressions, making it a smart base layer for everyday beds.

Firmness

Firmness describes how the foam feels when you lie on it. Back and stomach sleepers often prefer a firm foam for bed support, while side sleepers may want a softer surface.

Foam Type

• Polyurethane foam: versatile and easy to cut for support cores.
• Memory foam: contours to the body and eases pressure points.
• Layered builds: pair a firm base with a soft foam mattress topper.
