FoamRush 4 High Density Firm Upholstery Foam - Soft Support for Dining Chairs and Wheelchair Seat

High density foam has a compression rate of 44lbs, providing the perfect balance of cushioning and stiffness. It is soft yet firm enough to support individuals without compressing too much. Firmness is determined by compression, not density. To avoid a rock-hard cushion or a sinking mattress, it is important to check the compression or ild number. Compression refers to the pounds required to compress foam by 25% and still have it return to its original thickness. For example, a 4" thick piece of foam that needs 33 lbs to compress it by 1" and return to 4" has a 33 lb compression rating or ild (indentation load deflection).

All foam sheets are sold per sheet, not per yard. To open, use a ball point pen or pencil instead of a box cutter. Start with a small incision and break it from there. The durability of the foam is 7 to 10 years.

Medium density foam offers firmness and comfortable cushioning, with high-quality compression and durability to withstand heavy weights over time. A 50% restocking fee may apply on returns.

Our foam is certified for the highest quality, featuring Density: 1.8 Compression: 44 ILD, and a 100% recovery rate. Ideal for revitalizing chairs, sofas, cushions, and other high-density replacements, it provides the perfect balance of support, comfort, and durability. High density firm foam can last from 7-12 years in heavy traffic areas.
