4-Inch High Density Foam RV Mattress, Medium Firm, Made in USA

A compression rate of 44lbs is characteristic of high density foam, which offers the perfect balance of cushioning and stiffness. Despite its softness, it remains firm and supportive enough for individuals to sit comfortably without causing excessive compression. Firmness is determined by the compression, not the density, of the foam.

To avoid a cushion that feels rock hard or a mattress that sinks under pressure, it is crucial to check the compression or Indentation Load Deflection (ILD) number. Compression indicates the amount of weight required to compress a piece of foam by 25% and have it bounce back to its original thickness. For instance, a 4" thick foam piece that needs 33 lbs of weight to compress it by 1" and have it return to its full 4" thickness has a 33 lb compression rating or ILD.

High density foam is ideal for providing firmness with a touch of softness for comfort, making it popular for mattresses and cushions. Its high quality compression and material ensure durability even under heavy weight, lasting 7 to 10 years. It is recommended to use a ballpoint pen or pencil, rather than a box cutter, when opening the package.

Our foam is certified for quality, featuring a Density of 1.8, Compression of 44, and ILD with a recovery rate for durability. It is perfect for rejuvenating worn-out furniture such as chairs, sofas, and cushions. Versatile in usage, it can be added to sleeper sofas, platform bed frames, trailers, camper vans, boats, and RVs.

Cutting and customizing the foam is easy with tools like a sharp knife or electric hot wire foam cutter. Layers can be stacked for extra thickness or glued together to create wider pieces. It is recommended to follow care instructions such as allowing the foam to expand for 3 to 4 days after unrolling it from the shipping box. Local manufacture ensures quality and CertiPUR-US certification guarantees safety and environmental friendliness.
