High Density Upholstery Foam Cushion 18x18x3 Square for Dinning Chairs, Wheelchair

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, preventing excessive compression when sitting. Firmness is determined by compression, not density. To ensure you don't end up with a rock-hard cushion or a sinking mattress, check the compression rating or ILD number. Compression refers to the pounds needed to compress foam by 25% and have it bounce back to its original thickness.

All foam sheets are sold individually, not by the yard. Handle with care using a ballpoint pen or pencil to avoid damage. Cut a small incision to start and break from there. Our high-density foam is durable and can last 7 to 10 years, making it ideal for various applications requiring firm yet comfortable cushioning.

Our certified foam features a density of 1.8 and compression of 44 ILD with a 100% recovery rate for long-lasting durability. Perfect for revitalizing worn-out furniture, our high-density foam provides optimal support, comfort, and longevity. Designed for heavy use, our firm foam is built to withstand 7-12 years of wear and tear.

Foamrush prioritizes quality assurance with Certipur-US certified foam that is safe and regulated for consumer use.

Easy to customize with tools like knives or electric cutters, our foam can be stacked or glued together to fit your specific requirements.

Upon receiving your foam, open the package carefully and allow it to expand for 3 to 4 days. Avoid using sharp objects to open the box to prevent damage.
