For a great space-saving option to accommodate guests or other sleeping arrangements, we recommend the Daybed Pop-Up Trundle. This convenient twin-size trundle maximizes space in any room. It allows a mattress to pop up next to a daybed to turn a standard twin daybed into a king-size bed. For easy storage, this trundle bed conveniently drops down to store away underneath the daybed. The trundle unit only (not including mattress height) is 6 inches high when flat for storing, and 15 inches high when in its raised position. It measures 75L by 39W inches and fits a standard twin-size mattress (not included). Weight capacity is 250 lbs. Please note that a twin mattress is not included and needs to be purchased separately. We offer an excellent selection under the Daybed Mattresses tab. About Fashion Bed Group Leggett"s ornamental and bedding support lines are marketed as Fashion Bed Group.
