CertiPUR-US Certified Rubber Foam Sheet 5 in x 24 in x 24 in - High

In this review the focus is on a versatile upholstery and acoustic solution: the CertiPUR-US Certified rubber foam sheet in 5 in x 24 in x 24 in. The bottom line is simple - this is a firm, high density foam sheet that works well for seat replacement, cushions and studio acoustic panels. The reviewer found the foam comfortable yet supportive, easy to trim to size, and durable enough for long-term use, making it a practical choice for DIY upholsterers, musicians and small commercial projects needing reliable cushioning or sound treatment.

Key Features

• Same-size shipping: The foam arrives cut to the selected dimensions so you can use it immediately or trim it precisely with scissors or an electric knife.
• High density comfort: Premium upholstery foam with a higher density provides firm support and holds shape for seating and cushions without compressing excessively.
• CertiPUR-US certified: Independent certification ensures the foam meets emissions and durability standards for safer indoor use.
• Durability and recovery: With a 100% recovery rate and fire retardant properties, the foam is built to last several years with proper care.
• Wide range of uses: Suitable for poker tables, furniture cushions, boat and car seats, studio acoustic panels and many DIY or commercial upholstery applications.
• Dark charcoal color: The neutral dark finish hides wear and works with many upholstery fabrics and styles.

Who It's For

This foam is ideal for hobbyist upholsterers, home builders and studio owners who need a dependable, firm cushion material for seats, bench pads or acoustic treatment. Its cut-to-size shipping and ability to be trimmed with common tools makes it a good fit for DIY projects and small commercial repairs.

People who need ultra-soft or plush cushioning for luxury sofas may prefer a lower density or layered solution, and those needing custom molded shapes for specialized industrial uses should consider molded or specialty foams instead of a sheet product.
