Foamma 4 in x 22 in x 22 in High Density Upholstery Foam - 8 Pack

In this review the Foamma 4 in x 22 in x 22 in high density upholstery foam is examined for DIY cushion repair and replacement. The bottom line: this set of eight custom-cut foam blocks is best for homeowners and hobby upholsterers who need a durable, supportive replacement for chair and couch cushions; it stands out because the 1.8 density and 44 pound compression rate deliver firm, resilient support that keeps its shape. The reviewer found the compact packaging, CertiPUR-US materials, and the promise of full recovery within 72 hours practical for busy projects.

Key Features

• High density construction: The 1.8 density foam gives firm support suitable for seats that receive daily use and helps cushions retain shape over time.
• Reliable compression and recovery: With a 44 pound compression rate and 100% recovery rate, the foam provides consistent resilience for sitting comfort and long-term use.
• Custom cuts: Each order is custom cut to specified dimensions so pieces fit covers and frames without extensive trimming or modification.
• Certified materials: The foam is CertiPUR-US certified and made without ozone-depleting substances, which is reassuring for indoor use and longer-term durability.
• Compact packaging: The foam ships compactly to save space and expands to full size within 72 hours when opened, which is convenient for storage and staging projects.

Who It's For

This foam is ideal for DIYers replacing chair and couch cushion inserts, craft upholsterers making custom pillows, and anyone who needs consistent, firm support for seating that gets routine use. The pack of eight is particularly useful for multi-seat projects or keeping spares on hand.

It is less suitable for those who need a plush, soft feel or very specialized medical grade foams; customers seeking a noticeably softer, sink-in comfort profile should look for lower density or memory foam alternatives.

Pros & Cons

Pros

• Durable and firm support that holds up well under regular use thanks to a 1.8 density and good compression rate.
• Custom cutting reduces trimming work and increases the chance of a good fit for replacement cushions.
• CertiPUR-US certification and compact packaging make it practical and safer for indoor projects.
• Offers strong value for money when replacing multiple cushions or doing larger upholstery jobs.

Cons

• Firmness can be polarizing: some users may find the feel too firm while others prefer it very supportive.
• Customers needing very precise or unusual thicknesses should double-check measurements since custom cuts rely on accurate input.
