High Density Upholstery Foam Cushion for Dining Chairs and Wheelchair Seat Replacement

High-density foam features the perfect amount of cushioning and stiffness, with a compression rate of 44 lbs. It is soft yet still holds its firmness and support, allowing an individual to sit on it without compressing the foam too much. The compression, or the number of pounds necessary to compress a piece of foam 25% and still bounce back to the original thickness, is what determines the firmness, not the density. For example, a 4-inch thick piece of foam that requires 33 lbs. to pack it down 1 inch and have it return to its full 4-inch thickness has a 33 lb. compression rating or (ILD) - indention load deflection.

Compression means the number of pounds necessary to compress a piece of foam 25% and still bounce back to the original thickness. If you don't want a cushion that's hard as a rock or a mattress that sinks when you sit on it, you have to check the compression or ILD number. All foam sheets are sold per sheet, not per yard, and should not be opened with a box cutter. Instead, use a ball-point pen or a pencil to start by making a little incision and break it from there.

High-density foam is used for firmness yet relaxable cushion. It has high-quality compression and material to keep it lasting for longer periods of time, even when harsh weight is applied. The durability of high-density foam can last 7 to 10 years. However, a 50% restocking fee may apply for all returned items.
