Queen sofa bed: 3 ft deep by day, about 7½ ft at night
A queen sofa bed is 3 ft deep by day, about 7½ ft at night.
Sleepers look small in the showroom because they're closed. Open, a queen reaches about 90″ (229 cm) from the wall, though models vary, so look for the open depth in the listing. Add 24″ at the foot so a guest can walk around it: 114″, or 9½ ft, from the wall. Sleeper mattresses are 72″ long, shorter than a regular 80″ queen. And plan the coffee table: it sits exactly where the bed lands, so it has to move.
