What owners report

Owners on the maker's site mostly buy the Dozy for odd spaces such as RV twin beds, semi-truck sleepers and waterbed frames. They report a close fit to the ordered size, fast shipping and a comfortable medium feel; one RV owner found it slightly heavier than the original but still easy to lift on a hinged base.

Owners like

Fits custom and RV sizes closely
Ships quickly for a made-to-order bed
Comfortable for truck and RV use

Owners mention

A bit heavier than some factory RV mattresses (one owner)
