I haven't found them to compress. They're meant to go under heavy furniture, remember, so they seem to remain pretty true.

I don't cut them. I've used both the round and the square and they're smaller than the space where you attach them, so no need to cut. You could also get larger sheets or shapes and cut them down to size.

And for a buck for a sheet of 20, you can afford to replace them once a year or so if you need.
