Roy,
I have not tried chairs/lounges. Thought about it, but wondered how it would fit. Perhaps I should try one. What has worked best for me in these is a WetMutt dog kennel mat on the floor and a life preserver cushion behind your head. Many naps have been had over the years.
I should add, the cushion kept me out of a jam once. One day the warden came along. I am OOS there, but not Maine. License, plug, boat registration, pfd's etc. for the 18' tow boat. Everything was good until he said, where's the pfd in THAT boat? Didn't matter to him that you don't ride in it on open water. Lucky the cushion was in there, he said ok, but you should have a life jacket too.
