Has anyone washed one of these before?

Yep I have. I didn't put in a dryer so mine didn't shrink

I have and it went fine. I did only wash on a cold cycle though not warm incase it shrank but it came up good as new and was fine to put back on.

Awesome, I really didn't want it to shrink. How hard was it to put the cover back on?

It's a little bit of a pain. Just remember which shapes go where so it folds back up properly

What coops said ?
