It shouldn't be too hard to recover.

I pulled the sides of mine out the first summer, to clean and repair the frame.  The wooden fram is just screwed to the floor in a few places.  Once you remove the screws, it just lifts right out.

I recomend using some good glue and maybe a couple screws to firm up the frame before you reinstall it.  Ours was just stapled together and the staples were pulling out...
