Foamma 4-Pack 1 in x 18 in x 18 in High Density Upholstery Foam

In this review of the Foamma 4-Pack 1 in x 18 in x 18 in High Density Upholstery Foam, the bottom line is simple: it is a straightforward, American-made replacement cushion for dining chairs, wheelchairs and light upholstery projects that need firm support. The reviewer found the set best for anyone restoring multiple identical chairs or creating uniform seat pads, because the consistent high density core and compact 1 in thickness deliver reliable compression resistance and predictable feel across all four pieces.

Key Features

• Made in the USA: Ensures consistent manufacturing quality and materials for upholstery projects where uniformity matters.
• 1.8 High Density with 44 lb compression: Provides firm support that restores sagging seats and holds shape for extended use.
• 4-Pack convenience: Supplies enough identical squares to replace multiple dining chairs or make matching cushions for a set.
• Durability: Rated to last roughly 5-7 years in typical domestic seating applications, offering a cost-effective replacement timeline.
• Custom cut option: The seller accepts measurement requests for custom foam, making it flexible for nonstandard projects.

Who It's For

The Foamma 1 in squares are best for hobby upholsterers, homeowners refreshing dining room chairs, and caretakers replacing thin wheelchair seat pads who need a firm, uniform pad. The four-piece pack makes it practical when several seats must match in feel and thickness without the need to trim or pair different foam types.

Those who need very thick cushioning, softer plush seating, or professional-grade marine cushions with specialized shaping should look elsewhere or request a custom cut; the product is specifically a thin, high-density square meant for firm support rather than deep comfort layering.

Pros & Cons

Pros

• Uniform high density works well to restore firmness to worn kitchen or dining chairs.
• Made in the USA and sold as a 4-pack, which simplifies matching multiple seats.
• Seller offers custom cuts, so buyers with nonstandard sizes can get tailored pieces.
• Firm compression rating helps maintain shape and provides steady support for everyday use.

Cons

• At 1 in thickness some customers find the pad thinner than expected for plush seating needs.
• The firmness may be too rigid for users seeking a soft, sink-in cushion.
