Item Description

Anti-Microbial Polyurethane Foam is the standard foam for outdoor cushions and boat seats. A common choice for OEM boat builders, this polyurethane foam is formulated with a biocide, antibacterial agent to prevent mold and mildew growth. It has a medium firmness and a density of 1.8 lb./cu. ft. Polyurethane foam does absorb water, therefore, when using this foam for exterior cushions, we recommend wrapping it in silk film (plastic) to protect it from moisture.

Anti-Microbial Polyurethane Foam is excellent for use as boat seats and outdoor cushions. This foam is recommended for only occasional indoor use. It is not appropriate for applications that receive continuous daily use, like living room sofas, which require a higher density (2+ lb./cu. ft) foam. Additionally, indoor applications do not require the antibacterial agent.

Use an electric kitchen knife to trim the foam if needed. To glue two pieces of foam together, we recommend using 3M Super 77 Spray Adhesive. Foam can be glued on the sides to make larger pieces or layered to make thicker cushions. If layering different stiffness foams, the firmer foam should be on the bottom.

Very comfortable!

by -

This is a great piece of foam!! I reupholstered my living room chair and wanted to replace the uncomfortable cushion that came with it. This one is way more comfortable! I have a hard time getting my butt out of the chair now. :/ This cushion is not too dense and not too soft. The one that came with the chair was very dense and hard. This one has just the right amount of "sink" for my taste.
