Definitely easy to set up and use.  It was fully expanded in about 30 minutes but we let it air out for 24 hours before use.  It is firmer than I anticipated but comfortable.  We bought the queen size 14” deep mattress for use in our hard sided queen waterbed frame and it fit almost perfectly.  There is plenty of mattress extending above the wood frame and an approximate 1 inch gap at the head and foot of the bed which helps for putting on the fitted sheet.
