I sleep very well in the Vee berth of my 33 Morgan. The berth is quite large, and I purchased 3-inch thick memory foam that I cut to fit the berth. That foam goes on top of the cushions, and a custom fitted sheet goes over the top of everything. Makes for a very, very comfortable night's sleep.
I have also slept in the Morgan's quarter berth, which is very large as well, but if two people slept in there they would have to be very good friends. It too has the memory foam on top of the cushions and a fitted sheet.
