4 in x 22 in x 24 in High Density Upholstery Foam 3-Pack - Firm

In this review of the 4 in x 22 in x 24 in High Density Upholstery Foam 3-Pack, the bottom line is simple: this set targets DIY upholsterers and homeowners who need firm, long-lasting replacement cushions at an affordable price. The reviewer found the foam is noticeably firm with reliable resilience, making it a solid choice for seat repairs or couch cushion inserts where support and shape retention matter. The pack of three is practical for matching multiple cushions, and the custom-cut option means it is ready to slide into covers with minimal trimming.

Key Features

• Durable High Density: The 1.8 density foam provides firm support that is built to withstand daily use and retain shape for years.
• Compression and Recovery: With a 44 pound compression rate and 100% recovery, the foam quickly springs back to its original profile after sitting.
• Custom Cuts: Each order is custom cut so the cushion can be matched to a cover or frame with precise length, width, and height.
• Certified Materials: The foam is made without ozone depleting substances and carries CertiPUR-US style quality assurances for safer indoor use.
• Compact Packaging: The product ships compactly for easier transport and expands to full shape within 72 hours of opening.

Who It's For

This 3-pack is best for homeowners, small upholstery shops, and crafters replacing multiple seat cushions or tackling a sofa makeover who want a firmer, long-lasting feel. The set is particularly suited to living room seating and chairs that see daily traffic and need resilient support rather than a plush, sinking feel.

Those who want very soft, memory-style foam or who require exact factory-spec OEM cushions for highly contoured seats should look elsewhere. Also, buyers who need millimeter-perfect sizing should measure carefully and be prepared that some customers report mixed precision in size.
