FoamRush 7ft x 26ft x 26ft Upholstery Foam Cushion High Density

In this review the FoamRush 7' x 26' x 26' high density upholstery foam is judged on comfort, durability and versatility for chair and cushion replacement projects. The bottom line: this is a firm, CertiPUR-US certified replacement foam that delivers long-lasting support for dining chairs, wheelchairs, piano stools and other high-use seating where a firm, resilient cushion is needed. It is best chosen when durability and shape retention matter more than a plush, sinking feel.

Key Features

• High density construction: provides firm, long-lasting support designed for heavy traffic and frequent use.
• Measured compression (ILD): the foam's 63 ILD compression gives a clear indicator of firmness so buyers know it will resist excessive sinkage.
• Durability and recovery: formulated for a 100% recovery rate so the cushion returns to shape after use and is rated to last 7-12 years with normal wear.
• CertiPUR-US certified: independently certified for quality and safety, making it a reliable choice for home upholstery projects.
• Easy to customize: can be cut, trimmed, glued or stacked to create custom thicknesses and shapes for chairs, benches, RV seats and more.
• Wide project use: suitable for chair replacement, ottomans, boat seats, headboards and packing or craft projects that need firm foam.

Who It's For

This foam is aimed at DIYers, upholsterers and homeowners who need a firm, supportive replacement cushion for dining chairs, wheelchair seats, piano stools, workshop benches or other high-use seating. Its firmness and certified foam quality make it a good choice where longevity and shape retention are priorities.

People who prefer a very plush, soft sink when seated or who need a memory foam feel should look elsewhere, since this product is firm by design and its ILD and compression values favor support over softness.

Pros & Cons

Pros
