Installing new foam in couch cushions

My Joann's sells thick foam (if they don't have it in the store, they can order it for you). The problem is that is pretty expensive, so make sure you have a coupon!

I got foam from Joanna fabric store, measure the size if your cushions that you have or the covers . If the covers you will need to trim and can use an electric knife

I am thinking of doing the same thing for my couch which is too soft and squishy. I was going to try just adding more foam to what is already there.

Joann was very expensive. Check out Foam Factory. Info@foambymail.com 1-586-627-3626. We love the foam we received. Exactely right size, thickness and firmness.

Google to find a local foam store in your area. Take one of the old cushions with you as a guide. The people at the shop will help you measure and calculate how much you need as well as offer suggestions. The shop I have been going to for over 30 years also cuts to order.

For your foam, consider checking at Home Depot. They carry a 2'x6' piece of firm foam for about $25. You would probably have to double it to get a piece the is thick enough, but it will be much cheaper than the hobby shops.

have you tried putting a support board under your couch cushions? 1/4 to 1/2 inch thick plywood? the springs may be shot in your couch.
