Foamma 4 in x 30 in x 84 in Charcoal Upholstery Foam - Durable Comfort

In this review of the Foamma 4 in x 30 in x 84 in charcoal upholstery foam, the bottom line is simple: it is a practical, no-frills replacement pad for cushions and seat repair where long-lasting support matters most. The reviewer found the foam best for sofas, armchairs, and custom pillow projects that need firm, resilient fill. With a stated density of 1.4, 44 lb compression rate and 100% recovery, the foam delivers steady support for everyday use without feeling overly hard, making it a straightforward choice for DIY upholstery and craft projects.

Key Features

• Durable charcoal foam: The charcoal color and 1.4 density offer extra toughness for furniture that sees frequent use while remaining comfortable enough for daily lounging.
• Custom cuts: Each order is custom cut so buyers can get the exact sized pad they need for cushion replacement or a craft project without trimming large blocks at home.
• Resilient support: With a 44 lb compression rate and 100% recovery, this foam holds shape well and restores quickly after pressure, suited to seat inserts and couch cushions.
• CERTIPUR-US certified: Made without ozone depleting substances, the foam uses higher quality materials for safer indoor use and longer lasting performance.
• Compact packaging: The cushion is vacuum packed for easier shipping and handling, and it expands to full shape within about 72 hours when opened.

Who It's For

This foam is aimed at homeowners, upholsterers, and crafters who need a firm, long-lasting replacement pad for chairs, sofas, or custom pillows. It works well for repairing sagging innerspring cushions, rebuilding seat bases, or creating new cushion inserts where consistent support and durability are priorities.

Those seeking extremely soft, plush fills or specialty foams for high-end mattress toppers should look elsewhere, since this product emphasizes resilient support and durability over a very soft feel. Also, precise measuring is required because orders are custom cut and not easily returned if sized incorrectly.
