When you need an extra spare bed for that occasional slumber party or for unexpected guests, the Trundle for Daybed offers an ideal solution. It tucks neatly under most daybeds with 12" clearance. The trundle is simply designed for a timeless look that coordinates perfectly with all bedroom décor. Its four casters - locking and non-locking - allow you to easily slide the trundle into place. Metal slats are included to provide support and comfort so there is no need of a box spring. .
