Foam

I have couch which has removable 2 seats coushions and 2 back coushions.
The seats coushions are different from the back coushions. Each seat coushion is made of a single sheet of good quality foam which is coverd by a fabric with zipper, so its washable.
But the 2 back coushions are made of something like cotton stuffings (not a foam sheet) and the fabric does not have a zipper hence not washable.

Now my problem is even though my couch is in a good condition the back coushions have lost its shape and stiffness leading to back pain.

I’m thinking of replacing the back coushions similar to the seat coushions (foam covered with washable fabric with zip).

I have found the exact fabric in Joann’s. But I dont know how to purchase the foam and stitch the fabric cover with zip. Suggestions required. Should i good to a upholstery? how much would it cost? will they have the foam or is there another shop where we can choose our foam?

Joanns sells solid foam in various sizes. You can cut it with a serrated bread knife and then glue layers of if together to get the shape and size you need. But you really don’t want the back cushions to be foam ONLY as that will end up being rather uncomfortable — the back cushions need to conform to your back more than foam does. The best combination is to use a core of solid foam about 20 to 30% smaller than the final cushion and then wrap it with several layers of polyester fiber filling (which you can also get at Joanns, back in the upholstery department. After you’ve got it the shape and density you like, make a cover for the stuffing out of muslin so you can slip off the outer cover to clean it.

I’ve made sofa cushions this way several times.
