It was easy to put the cover on.  The product is not it's full size for 6 hours but you can put the cover on after 25 minutes.  I advise you to do it that way.
I love the material.  It is more comfortable than it looks.  It is a comfortable bed.  Yesterday I accidentally knocked over a coke and some spilled on the couch.  I grabbed a rag and wiped it up and the couch didn't even feel wet.  It must be treated.  It is very attractive.  It was a good bargain.
