Note: Using a mattress that is 8" or less in thickness for both the bed and the trundle is suggested. This will allow adequate clearance for the pop up trundle and the mattress will not sit too high on the daybed.
A trundle bed is the combination of a twin bed and a trundle, a slightly smaller bed on rollers or casters that can be put beneath the twin bed for storage. Trundle beds are a great space saver and allow for an extra separate bed to be available when necessary without requiring the second space constantly. The lower bed on some trundles can "pop-up" to be the same height as the twin it is stored beneath, creating a regular-height bed. All of our trundle beds conform to standard twin mattress sizes - 39"w x 75"l.
