up the seat cushions before with the quilt batting and it works IF your foam isn't in to bad a condition. If the foam is really compressed, I have tried several different things and now I just save myself a lot of time and headache and just buy new foam. Some places will cut the foam to your measurements and others you just have to take it home and cut it yourself ( an electric carving knife is the best way to cut it). It is a little more cost than just the batting, but I have been very happy with the results and it is much less expensive than having it done. If your cushions are spring type, if you want to and feel comfortable doing it, you can retie your springs. I used to do this, but now, I take them in and have them redone. Just easier on my nerves and hands. That is what happens when you get old, :) Good luck.

p.s. there are also special boards things that you can buy and just slip them in under the cushions. I just have never tried them.
