what does daybed mean
A daybed is a piece of furniture that is used like a couch and a bed. It's usually raised high up off the floor (like a bed) but with railings on 3 sides (back and 2 sides) like a couch.
a bed during the day :D
A daybed is the type of bed that has a "headboard" which wraps around three sides of the bed, so that when you make it, it looks almost like a couch.
