Foamma 4" x 24" x 24" Foam Cushion Inserts (2-Pack) - High-Density Outdoor/Indoor Couch Support, CertiPUR-US

Foamma's 4" x 24" x 24" (2-pack) high-density foam pads are durable replacement couch cushions that restore firm, long-lasting seating support for outdoor and indoor sofas.

These two square foam inserts are designed as upholstery-grade replacement cushions for patio furniture, benches, and sofas when covers have worn or padding has flattened. Made in the USA and CertiPUR-US certified, the Foamma pads balance resilient support with moderate comfort so cushions keep their shape for years. Covers are not included — these foam blocks are intended as the core support piece inside your existing cushion shells or slipcovers.

Will these foam cushions keep my outdoor seating from sagging?

Yes. The high-density construction provides a firmer, more supportive base compared with low-density fillers, helping seat cushions hold their shape and resist rapid compression. That means less sinking and more consistent comfort across the cushion surface.

• 1.8 high-density rating for durable support
• 44 lb. compression rate to reduce sagging over time
• Made to retain form for an estimated 7–10 years with typical use

Are these suitable for outdoor use and safe for indoor air quality?

These foam inserts can be used on covered patios and other sheltered outdoor seating, but they are not water-resistant on their own — pair them with outdoor-rated covers for full weather protection. They are CertiPUR-US certified, manufactured without harmful heavy metals or ozone-depleting substances and emit low VOCs for safer indoor air quality.

• CertiPUR-US certified materials
• Low VOC emissions for indoor environments
• Use with water-resistant covers for outdoor exposure

Can I get a different size or shape for a custom project?

Foamma offers custom cutting if the standard 4" x 24" x 24" blocks don't match your cushions. Contact the seller with your dimensions and desired shape — they can cut squares, rounds, stars, or other bespoke profiles to fit bench seats, unique sofa cushions, or specialty upholstery projects.

• Custom cuts available to exact dimensions
• Shapes tailored for sofas, benches, and specialty cushions
• Ideal when replacing nonstandard or vintage cushion cores

How do these foam pads compare to full replacement cushions?

These are foam cores only; covers must be reused or purchased separately. Compared with complete replacement cushions, buying foam cores lets you match density and firmness precisely and often saves money when your existing covers are still in good condition.

• Sold as core inserts — covers not included
• Great choice for reupholstery or refreshing worn interiors
• Two-pack provides matched support across a two-cushion seat

Who is this for: homeowners, upholstery hobbyists, and small businesses looking to revive worn seating without replacing entire cushions will appreciate these Foamma blocks. They suit people who want a firmer, lasting base for patio sofas, swing benches, dining chairs, or indoor couches and who plan to reuse or replace cushion covers separately. If you need water-resistant pads for exposed outdoor use, combine these cores with appropriate outdoor covers or protective liners.
