The optional Night & Daybed Extension™ comes packed two-per-box and fits onto a pair of Cinnamon Storage Drawers. The drawers give you plenty of storage and keep the mattress supports stashed at the back of the drawer till they're needed.
When it's time to convert to the full-size sleep position, the drawers pull out and the mattress supports are easily pulled into place. Set of two drawers pictured above. See the series of images below showing the twin-size daybed convert into a full-size The NIGHT & DAYBED™.
