Foam Closed Cell Natural is an antimicrobial Ensolite closed cell PVN foam that is designed for flotation gear and marine cushions. Ensolite foam is 3 times as firm as polyurethane foam and resists moisture absorption, weather-aging and mechanical abrasion. Ensolite does not support combustion. This closed cell foam is excellent to use for cockpit cushions, life jackets, bosun's chairs, or anywhere a firm, thin cushion is needed.

Glue pieces of foam together with adhesive to form custom foam shapes and sizes and to reduce waste.

Closed cell foam may shrink over time, especially in colder weather. Note that thicker foams tend to be more stable than thinner foams.

Note: Items are compressed for shipping, we recommend unrolling as soon as possible. Compressed foam takes up to a week to regain its original size and shape. Allow foam to fully decompress before cutting or using in a project.

Note: The manufacturer lists the width of the sheet as 56 inches; however, they have a +/- 3% tolerance on the width (54 to 58 inches). Please note that the foam thickness can also vary from 1-1/2 to 2 inches.

I’m making a pair of cockpit cushions.

If you have 1 inch cockpit cushions this is what you need. You can add a softer 1/2 inch topper for a little more comfort but this will keep your cushions from sagging corners and miss lined seems. Easy to cut with a ceramic knife.

It was a bit larger than I ordered so I was very happy with that. It was very tightly rolIed and had some wrinkles in it, I was worried about that but it flattened out in a few days when I put weights on it. Don't even bother trying to cut it with a serrated blade. My skill saw didn't even scratch it Literally bounced off. Use a very sharp knife. I am replacing all my cushions on my boat and am very happy with my purchase.
