How Long Do Seat Cushions Last?

This is a question many people have. It all depends on how you’re using the seat cushions. For instance, if they are on a boat or in a camper, they may not last as long. That’s because sand, moisture and other contaminants can get embedded in the foam rubber. Once this happens, it’s only a matter of time before the foam will start hardening. It may develop a foul odor. That’s a sure sign that it’s time for new seat cushions.

Does flipping the cushions help?

This can definitely prolong the life of your cushions. Flip them at least every six months. In most cases, you should replace seat cushions about every two years. If you notice a bad smell or the cushions become too lumpy, then change them sooner.

What type of foam is best?

This depends on your own preferences but memory foam is quite popular and very affordable. It can be cut to any size. You can purchase the foam and make covers yourself or buy them already covered. Latex is also a good outdoor foam for seat cushions. It’s comfortable and will last for years under the right conditions. Convoluted foam is typically used for mattress toppers.

If you need to make cushions or a couch for your camper or boat, then consider purchasing a solid sheet of foam rubber. These come in 76” X 82” sheets and are available in thicknesses up to six inches. You can cut this type of foam very easily and make all sorts of seat cushions, mattresses or couches.
