5 in x 20 in x 20 in Upholstery Foam Padding 3 Pack - High Density

In this review the Foamma 5 in x 20 in x 20 in High-Density Upholstery Foam Padding 3 Pack is evaluated for anyone replacing cushions or working on upholstery projects. The bottom line is that this set is aimed at DIYers and small upholstery shops who need firm, consistent foam blocks that are made in the USA and carry a CertiPUR-US assurance. The reviewer found the product most valuable for seat repair, craft projects, and custom pillow inserts because of its firm high-density feel and removable organic cotton cover that makes maintenance straightforward.

Key Features

• Made in America: Manufacturing in the USA ensures consistent production standards and traceability for each foam block.
• High density support: The firm 3 in high-density foam provides stable, long-lasting support for cushions, pillows, and seat repairs.
• Organic cotton cover: The removable cover unzips for machine washing to keep the foam protected and easy to maintain.
• Custom sizing available: The brand offers custom foam sizing and options if the standard 5 in x 20 in x 20 in blocks do not meet project needs.
• CertiPUR-US certified: Made without ozone depleting substances and certain heavy metals, helping reduce indoor VOC exposure.

Who It's For

These foam blocks suit hobbyists, upholsterers, and homeowners repairing chairs or couch cushions who want a firm, stable pad. The 3 pack format is convenient for replacing multiple cushions or creating matched inserts for bench seating and custom pillows.

Those who prefer a very soft, plush surface or require foam with a plush top layer should look elsewhere; this product is intentionally firm and designed for support rather than a pillowlike sink. Also, buyers needing exact nonstandard dimensions should contact the maker for a custom order rather than assuming off-the-shelf sizes will be altered.

Pros & Cons

Pros

• Firm, supportive feel that holds shape well under regular use.
• Removable organic cotton cover that can be unzipped and machine washed for easy care.
• CertiPUR-US certification reduces concerns about heavy metals and high VOC emissions.
• Made in the USA which can mean more consistent quality control and faster custom service.

Cons

• Firmness and density receive mixed feedback; some may find the foam too stiff or not dense enough for certain applications.
• Standard size may not fit every project without ordering a custom cut.
