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

High density foam has a compression rate of 44lbs, providing the perfect balance of cushioning and stiffness. It remains soft while maintaining firmness and support for comfortable sitting without excessive compression. Firmness is determined by compression, not density. To avoid overly hard cushions or sagging mattresses, it is important to consider the compression or ild number. Compression indicates the pounds needed to compress a piece of foam by 25% and have it return to its original thickness.

For example, a 4" thick piece of foam requiring 33 lbs to compress it 1" and return to 4" thickness has a 33 lb compression rating or ild - indention load deflection. It is recommended to open the foam with a ballpoint pen or pencil rather than a box cutter for durability, as high density foam can last 7 to 10 years. This type of foam is ideal for firmness with added softness for comfort, making it popular for mattresses and cushions due to its high-quality compression and durability even under heavy weight.

When ordering foam, it is essential to know the size and height of the mattress and to consider the height of the bed frame or foundation to ensure a proper fit. The foam should be combined with these measurements to determine the overall height of the sleep system. Note that the cover is not included and a 50% restocking fee may apply for returns.

Our foam is Certipur-US Certified, with a density of 1.8, compression of 44, and ILD for recovery durability. It is suitable for revitalizing chairs, sofas, cushions, and other high-density replacements due to its balance of support, comfort, and longevity. Designed for heavy traffic and lasting approximately 7-12 years, our firm foam is versatile and customizable for various uses, including sleeper sofas, bed frames, and recreational vehicles.

Foamrush's foam is safe and high-quality, cut to order for customer satisfaction. It can be easily customized for different sizes and shapes by trimming edges, stacking layers, or gluing pieces together. Care should be taken when opening the package to avoid damaging the foam, and the foam should be unrolled to relax upon removal from the shipping box.
