FoamRush 5ft x 28ft x 28ft Upholstery Foam Cushion High Density - Firm

In this review the FoamRush 5' x 28' x 28' Upholstery Foam Cushion is evaluated as a practical replacement foam for chairs, wheelchairs, and DIY upholstery projects; its biggest selling point is the balance of firm support and long-term durability. The reviewer found it most useful for restoring worn seating and crafting custom cushions, noting the foam is CertiPUR-US certified for quality and built to withstand heavy use. Buyers should expect a noticeably firm feel aimed at support rather than plush softness.

Key Features

• High density formulation: Designed to deliver firm support that resists rapid compression, making it suitable for high-traffic seating and heavy-use applications.
• Compression and firmness: With a listed compression of 44 ILD the foam holds shape under load while still providing cushioning for sitting without collapsing.
• Durability: FoamRush rates the foam to last approximately 7-12 years under normal use, offering a long-lived replacement option for older cushions.
• Certified quality: The foam is CertiPUR-US certified for quality assurance and manufactured locally to meet environmental and safety standards.
• Easy to customize: The foam is simple to trim, slice, glue, and layer so it can be tailored for dining chairs, patio cushions, stools, RVs, boats, and other projects.
• Recovery and resilience: The foam has a recovery rate and durability designed to bounce back after heavy use instead of staying compressed.

Who It's For

This foam is aimed at homeowners, upholsterers, and makers who need a firm, high density replacement for dining chairs, wheelchair seats, benches, or workshop projects where support and longevity matter. It is also a good fit for outdoor cushion replacement when a firm profile is acceptable and durability is required.

Shoppers who prefer a very soft, plush cushion or who are sensitive to firm seating should look elsewhere or consider layering softer foam on top, since several users and the reviewer noted the firmness can feel strong and some size measurements were reported as inconsistent by customers.
