Foamma 6 in x 28 in x 28 in High Density Upholstery Foam Padding

In this review of the Foamma 6 in x 28 in x 28 in High Density Upholstery Foam Padding, the bottom line is simple: this is a practical replacement foam for DIY cushion and seat repair where firmness and long life matter. The reviewer found it best for people restoring chairs, couches, or custom pillows who want a firm, resilient core without overspending. It ships compactly and arrives ready to trim to size, and while some decompression issues were noted by buyers, the overall feel, density and recoverability make it a solid choice for furniture that sees daily use.

Key Features

• Durable high density foam: The 1.8 density construction provides firm support that stands up to regular use and helps cushions keep their shape over years of seating.
• Custom cuts: Each order is cut to the requested dimensions so the foam fits covers and frames closely for an easier upholstery or replacement process.
• Optimum comfort: With a compression rate around 44 pounds and a 100% recovery rate, the foam balances firmness with resilient support for comfortable lounging.
• CERTIPUR-US certified materials: The foam is made without ozone depleting substances, which is useful for buyers concerned about material standards and indoor air quality.
• Compact packaging: The foam ships compressed for easier transport and expands back to shape, typically fully within 72 hours when opened.

Who It's For

This foam is aimed at DIY upholsterers, hobby crafters, and homeowners repairing seat cushions who need a firm, high density insert that will provide long lasting support. It works well for dining chairs, replacement sofa cushions, and custom pillows when you want a resilient core rather than a plush sink-in feel.

People seeking ultra-soft, plush cushioning or rapid full expansion out of the box may want to consider other foam firmness levels. Also, if exact instantaneous decomposition back to full loft is critical for your project, note that some buyers report slower or incomplete decompression initially.

Pros & Cons

Pros

• Firm yet comfortable feel that restores a tired seat to like-new support.
• Custom cut sizing makes it easy to get a close fit without extensive trimming.
• High density and 100% recovery rate mean the foam resists sagging over time.
• Materials are CERTIPUR-US certified, offering reassurance on composition.

Cons

• Some customers report the foam does not fully decompress immediately and may take up to 72 hours or longer to regain full shape.
• Firmness may be too rigid for those who prefer a softer, plush seating surface.

Our Verdict
