The Clara Comfort King 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. This Clara Sleeper is quality you can count on. Small spaces are not an issue with this sleeper, which requires zero wall clearance and can be disassembled to fit through any narrow hallway or doorway. Available in other sizes and configurations via special order.
