FOAMMA 1 in x 24 in x 34 in High Density Upholstery Foam Cushion

In this review the FOAMMA 1 in x 24 in x 34 in High Density Upholstery Foam Cushion is evaluated for anyone replacing seat cushions, reupholstering furniture, or building custom cushions. The bottom line: this sheet delivers firm, long-lasting support with a 1.8 high density and a 44 lb compression rate that makes it well suited for daily-use seating. The reviewer found the foam comfortable, quick to recover to shape after unpacking, and versatile for a wide range of projects thanks to Foamma's custom cutting options and US manufacture.

Key Features

• Made in USA: Manufactured domestically so buyers get consistent quality and materials sourced under US production standards.
• High density support: The 1.8 density with a 44 lb compression rate provides firm support and resilience for seats that see daily traffic.
• 100% recovery rate: The foam reliably returns to its original thickness after compression, helping cushions keep their shape longer.
• CertiPUR-US certified: Made without ozone depleters, heavy metals, regulated phthalates, and low VOC emissions for better indoor air quality.
• Custom cut options: The company will cut sheets to exact sizes and many shapes, which simplifies replacements for odd-sized or specialty cushions.
• Packaging and handling guidance: Sold per sheet and may arrive vacuum packed or rolled, with clear instructions to open immediately and allow up to 72 hours to regain form.

Who It's For

This foam is best for DIY upholsterers, furniture repair shops, and homeowners who need a firm, long-lasting seat cushion for sofas, chairs, boat seats, or auto applications. The high density and 44 lb compression rate make it a strong choice where durability and support are priorities rather than plush softness.

People seeking very soft, pillow-like comfort or specialized viscoelastic sinking feel should look at memory foam or gel memory foam alternatives offered by the brand. Also, buyers who cannot wait for the 72 hour recovery window after unpacking should plan accordingly.

Pros & Cons

Cons

• Firmness may be too dense for users who prefer plush or soft seating feel.
• Vacuum packed or compressed shipments require up to 72 hours to fully recover, which delays immediate use.
