High Density Upholstery Foam 1 in x 28 in x 28 in - Durable Cushion

Our review of this 1 in x 28 in x 28 in high density upholstery foam finds it best suited for DIY furniture repair and craft upholstery where durable, supportive padding is required. The single biggest reason to buy is its firm 1.8 density construction that delivers resilient support and long-term shape retention for chair and couch cushions, making worn seating feel noticeably firmer and refreshed without overspending on custom upholstery work.

Key Features

• Durable high density foam: The 1.8 density provides firm support that stands up to daily use in living room chairs and frequent seating areas.
• Custom cuts: Each order is custom cut so customers can get exact dimensions to fit cushion covers seam to seam for a precise replacement.
• Optimum comfort: A compression rate of 44 pounds and 100% recovery rate deliver consistent support and quick rebound after sitting.
• CERTIPUR-US certified: The foam is made without ozone depleting substances, which is useful for buyers concerned about material safety and off gassing.
• Compact packaging: Foam ships tightly compressed for easier transport and expands back to shape within 72 hours when opened.

Who It's For

This foam is aimed at home upholsterers, crafters, and homeowners repairing cushions who need a firm, longlasting insert for chairs, sofas, or bench seating. It is particularly well suited to projects where a supportive, dense feel is desired rather than a plush, sinking cushion.

Those who want very soft or slowrebounding fillings should look elsewhere, and if you need immediate full thickness on day one be aware the foam may take up to 72 hours to fully expand from compact packaging. Measure your cover seam to seam before ordering to ensure an accurate fit.

Pros & Cons

Pros

• Firm, dense support that restores sagging cushions and improves seating ergonomics.
• Custom cut sizing makes it easy to replace oddly sized inserts without trimming at home.
• Certified materials reduce concern about harmful blowing agents and odors.

Cons

• Compressed packaging means the foam can take up to 72 hours to fully decompress and some customers report slower or incomplete decompression.
• Higher firmness may not suit those who prefer softer, plush cushions.

Our Verdict

This high density upholstery foam is a practical, cost effective choice for DIY cushion replacement when firm support and long life are priorities. It offers good value for upholsterers and homeowners who measure carefully and who can wait for the foam to fully expand; those seeking very soft seating should consider a lower density option.
