Foamma 8-Pack 2 in x 18 in x 18 in High Density Upholstery Foam - Firm

In this review the Foamma 8-Pack 2 in x 18 in x 18 in high density upholstery foam is examined for anyone needing replacement chair cushions or DIY upholstery inserts. The bottom line: this pack is best for people who need consistent, firm, easy-to-cut sheets that hold shape over time. The reviewer found the foam's firm feel and high density useful for dining chairs, retro patio seats, and wheelchair cushions, and the fact it is made in the USA and CertiPUR-US certified was a decisive selling point for durability and indoor air quality.

Key Features

• Made in USA: The foam is manufactured domestically, offering traceable quality and consistent production standards for upholstery projects.
• High density 1.8: The 1.8 density with a 44 lb compression rate provides a firm support profile that keeps cushions from sagging quickly.
• Eight sheets included: This pack contains eight 2 in x 18 in x 18 in pieces, giving enough material for multiple chair cushions or a set of replacements.
• CertiPUR-US certified: Made without ozone depleting substances and heavy metals, the foam has low VOC emissions for better indoor air quality.
• Custom cut options: The seller can custom cut shapes and sizes, which is valuable for nonstandard furniture like round or heart-shaped cushions.
• Packaging guidance: The foam may arrive vacuum packed, rolled, or compressed and recovers to original shape in up to 72 hours when opened properly.

Who It's For

This foam pack is ideal for DIY upholsterers, homeowners restoring retro patio or dining chair cushions, and caretakers replacing wheelchair seat cushions who need firm, long-lasting support. The firm feel and high density suit seat applications where structure and edge support matter more than sinking comfort.

People seeking plush, slow-response memory foam or very soft seating should look elsewhere, as this is a firm, high density upholstery foam rather than gel memory or soft comfort layers. If you need a single oversized sheet or an unusually thin layer, ask about a custom cut first.
