The Clara Comfort Queen Plus Sleeper w/ 5” Premium Foam Mattress's standard track arm sports a little extra: attached soft curve padding on the arm interior, for structured support that looks as good as it feels. The Clara Comfort Sleeper is quality you can count on. Small spaces are not an issue with the Comfort Sleeper which requires zero wall clearance and can be disassembled to fit through any narrow hallway or doorway. Shown as Queen Plus size sleeper, but available in other sizes and configurations via special order.
