FoamRush 5 in x 26 in x 32 in Upholstery Foam - High Density Firm

In this review the FoamRush 5 in x 26 in x 32 in Upholstery Foam is evaluated for people who need a reliable, cut-to-size replacement cushion that balances firmness and comfort. The single biggest reason to consider this foam is its high density and CertiPUR-US certified construction, which delivers a firm supportive feel with a 100% recovery rate designed to last. For anyone restoring dining chairs, wheelchair seats, benches, or craft projects where durability matters, this foam aims to revive worn seating without the sink-in feeling of softer options.

Key Features

• High density construction: Provides firm support that resists rapid wear and is built for heavy traffic and frequent use.
• Compression / ILD rating: A 63 ILD compression characteristic gives a noticeably firm feel while still offering some cushioning for seated comfort.
• Durability: The foam is formulated for long service life with a claimed 7-12 year lifespan under normal use, making it suitable for long-term upholstery projects.
• CertiPUR-US certified: Made with certified materials to meet quality and safety expectations compared with non-regulated foams.
• Easy to customize: Cuts cleanly with common slicing tools, can be layered or glued to change thickness, and ships cut to order for tailored replacements.
• Wide project range: Useful for chair cushions, wheelchair seats, boat and RV seating, ottomans, headboards, and other DIY repairs or craft applications.

Who It's For

This foam is best for homeowners, upholsterers, and DIYers who need a firm, stable cushion replacement for chairs, benches, or mobility seating. It suits projects that demand long-lasting support, such as dining chairs that see daily use or seating in boats and RVs where resilience matters.

Those who prefer a very soft, plush sink-in feel or who need contouring memory foam for pressure relief should look elsewhere; this product is specifically a high density, firmer option and is intended to hold shape rather than mimic a plush mattress topper.

Pros & Cons

Pros

• Consistent firm support that helps restore sagging cushions and keeps seating level.
• CertiPUR-US certification gives confidence in materials and manufacturing standards.
• Good customization options: easy to cut, stack, and glue for tailored thickness or width.
• Durable formulation with a 100% recovery rate that holds up over time.

Cons

• Cut quality is reported mixed by some buyers, so edges may require trimming or finishing for a pristine fit.
• Firmness may be too stiff for users seeking plush or pressure-relieving foam.

Our Verdict

The FoamRush 5 in x 26 in x 32 in Upholstery Foam is a solid value for anyone needing a firm, durable replacement cushion that restores support without excessive sink.
