Foamy Foam High Density 5 in Thick Upholstery Foam - Durable Support

In this review the Foamy Foam High Density 5 in Thick Upholstery Foam is evaluated as a practical replacement foam for cushions and upholstery projects. It is best for homeowners and hobbyist upholsterers who need a single-piece cushion replacement with reliable firmness and long-lasting support; the single biggest reason to buy is the consistent 1.8 density and 44 ILD that deliver firm, durable cushioning without guessing at suitability. The review focuses on real-world use, ease of cutting to fit, and the unpacking/decompression step after shipping.

Key Features

• High density construction: The 1.8 density provides steady support that helps cushions hold shape under regular use.
• Balanced firmness: The 44 ILD compression rating offers a firm but comfortable feel suited for seat and couch cushions.
• One-piece size: You receive a single 5x30x84 piece that fits long bench and couch cushions without seams in many applications.
• Custom sizing available: The seller cuts 1-7 in thickness and a wide range of widths and lengths, so custom projects can be accommodated by request.
• Made in the USA: Domestic manufacture means consistent cutting and packaging standards you can expect in upholstery supplies.
• Decompression guidance: The foam ships compressed and will regain full volume if unpacked and allowed to lay flat for 2-3 days.

Who It's For

This foam is ideal for DIYers replacing seat cushions, couch cushions, or long bench cushions who need a firm, long-lasting core and who are comfortable trimming foam to exact measurements. It also suits small upholstery shops that want a ready-made 5x30x84 piece to speed repairs.

It is less appropriate for someone who wants ultra-soft, sinking cushions or for projects that require specialized laminated layers or integrated springs; those users should look for other foam types or multi-layer systems designed for plush seating.

Pros & Cons

Pros

• Consistent density and ILD deliver dependable support that maintains shape over time.
• Easy to cut and size for custom cushion projects, making installation straightforward.
• Single large piece covers long bench and couch cushions without seams for a cleaner finish.
• Customers report good quality and cushioning performance for refreshing older furniture.

Cons

• Ships compressed, so you must unpack and allow 2-3 days for full decompression before final fitting.
• The firmness may be too stiff for users who prefer plush, low-resistance seating.
