Our Duvalays comprise memory foam mattress, duvet and 'sleeping bag' arrangement that holds it all together. When not in use they roll up into their storage bags. They are very comfortable to sleep in but, as you can see, they are quite bulky.

If we are camping with awning or sunshade erected, we usually leave the bed made up and live outside. If not, each morning we put beds and pillows on one of the side benches and use the other side for sitting and dining. Come bedtime it's a simple matter to remove table, make up bed base and drag the bedding into place. Well, it works for us.
