High Density Foam Olympic Queen Mattress Replacement for RV, Extra Firm, Made in USA

High density foam with a compression rate of 44lbs provides the perfect balance of cushioning and stiffness. It remains soft while maintaining firmness and support, ensuring that it does not compress too much when sat upon. Firmness is determined by compression, not density. To avoid overly hard cushions or sinking mattresses, it is crucial to check the compression or ILD number of the foam.

Compression refers to the pounds needed to compress a piece of foam by 25% and have it return to its original thickness. For example, a 4" thick foam requiring 33 lbs. to compress it down 1" and bounce back to 4" has a 33 lb. compression rating or ILD - indention load deflection. When opening the foam, it is recommended to use a ballpoint pen or a pencil instead of a box cutter for durability.

High density foam, known for its firmness with a touch of softness, is widely used for mattresses and cushions due to its quality compression and durability. It can withstand heavy weights and last for 7 to 10 years. It is essential to measure the size and height of your mattress beforehand to ensure you order the correct size. Combine the height of your bed frame or foundation with the mattress to determine the overall height of your sleep system.

Foamrush's foam is CertiPUR-US certified for quality assurance and is designed for various applications to revamp worn-out furniture. The high density firm foam is suitable for heavy traffic areas and is built to last for 7-12 years. The foam is safe, environmentally friendly, and cut-to-order for customer satisfaction. The included canvas cover adds a stylish touch and is durable for outdoor use, featuring a zipper closure and machine-washable fabric.

The versatile high density foam mattress can be used in sleeper sofas, bed frames, trailers, campers, boats, and more. To care for your foam, open it immediately upon receipt, avoid using sharp objects during unboxing, and allow 3-4 days for the foam to fully expand. Follow these care instructions to ensure the longevity and quality of your foam product.
