The wonders of foam can be applied to a wide range of applications. With our Dryfast foams, you get an option designed specifically for use in wet environments.

Dryfast foams are suited for outdoor use where moisture and precipitation like rain is prevalent, such as in patio furniture, including under Phifertex material, or in marine cushioning on personal watercraft. The large, open cells provide a degree of airflow not present in other foams, allowing it to dry quickly, even after complete saturation. The Dryfast formula is anti-microbial and helps suppress microorganism growth, common in damp areas. Because of the anti-microbial formula and air circulation, Dryfast foam could also be used in home products like bedding for those with health concerns.

We offer this type of foam in several options to help you get the right outcome for your application. Choose from a range of thickness of 1 inch to 6 inches to get the right amount of cushioning for your preferences. We also offer this foam in half and full sheets sizes, so you get as little or as much as you need. We even do custom cutting with this reliable foam for a more precise option. We can cut custom sizes for any project for a high performing solution perfect for wet locations. Please Contact Us with any questions regarding this product or custom cutting for further assistance.

NOTE: Not tested for use in aquariums.

Custom Cutting is Available!
We can cut custom sizes of Dryfast foam for any project you may have. See Seats and Cushions: Dryfast Foam for pricing details.

Manufacturing Tolerances
Products may carry a size tolerance depending on the style and job. Please see our Tolerance Table.

Standard Sheet Sizes/Quality
Standard sheets of foam are cut slightly larger than the listed size to compensate for shrinkage during packaging, transit, and delivery. Sheets may contain rough edges. Any yellowing/discoloration of the foam is a byproduct of exposure to air and light and does not represent a flaw, damage, or defect in the material.

This dry-fast foam was denser than I expected! Perfect for our boat seat cushions with outdoor UV fabric! Very supportive, no additional supporting foam was needed.

The foam came well wrapped and secure. It expanded fully in a matter of hours. The foam works very well. I cut it easily with a serrated knife and it dries quickly.
Great for dog travel crate
John | April 4th, 2023
I use this for our medium dog crate for airline use, with some absorbent pads beneath. It's incredibly comfortable and breathable for the dog, and allows any water/urine to pass through to the pad below.
Exactly what I needed

I purchased this 2” quick dry foam to add to outdoor cushions that were a bit flat. It was very easy to cut to size and squeeze into the cushions. Now they are super comfy. Easy to use and quick delivery.

This was my first order with The Foam Factory. The foam came in quicker than I expected and it was a great quality. I will definitely be ordering from them again. Definitely satisfied.
Always delighted
Patty | August 29th, 2022
This is my third order of the dry fast foam. It is just perfect. It seems a bit “stiff” at first when you sit on it, but you quickly realize it is just what you want; it doesnt bottom out, it supports you, it is soft for hours of sitting or reclining. I keep ordering it for friends to “fix” the cushions they have bought commercially that are too flat and limp.
Dryfoam for outdoor cushions
Janet | July 13th, 2022
This was a very good quality dryfo at a reasonable price. I can buy this locally, but they only sell it in large sheets, and the price is a lot higher. I will buy from them again.
Great product!

Quality Products and great customer service
Sue LaPlant | March 16th, 2022
We have outdoor sofa, loveseat, and a chair that needed to make over since San Diego gets lots of sun. Although this was the first time to buy from the Foam Factory, the service and quality of products [Dry- fast outdoor foam and dacron were better than I had anticipated. Initially, I forgot to order dacron but sent an email to add dacron to the same shipment, they responded right away and they were able to ship together. The foam’s thickness and quality is exactly what I wanted and the dacron was thick also. I will definitely buy these products from the Foam Factory. I am very pleased!
Great Product and Great Service

We have just completed our outdoor cushions for our client. The dry fast foam is excellent! They left them out in the rain and were amazed that they came back to dry cushions!
