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.

Very nice foam. I’m not experienced with closed cell foam, but it worked perfectly for my seat.

It was just what I needed for the seats. I ordered the foam sample box which was a great help in deciding what I should order. The site and the service was was easy to navigate and the delivery was fast. I also like the "How To" which is so helpful. I will definitely be ordering again. The only downside was that the end where the roll started did not return to a useable shape but stayed crimped up. I managed to work around it so the cushion seats were flat with good vertical sides.
