Daybeds with trundles maintain the look of a more formal sitting space for daytime use but add convenient, hide-away sleeping space for the night. There are two main types of trundle daybeds: the traditional roll-out mattress and the pop-up frame that raises to the same height as the main bed.
Traditional trundle beds roll out from beneath the daybed's frame and remain at a lower level. Some are attached to the bed frame, while others glide out and can be placed farther from the main bed. A pop-up trundle can be raised and joined to the main bed to form a larger single-bed area. Most pop-up frames can also be moved apart to create separate single beds.
Daybeds with trundles are especially useful in children's rooms or guest rooms, because they can accommodate extra visitors. Children's rooms are often play areas during the day, and having two full-sized beds would take up valuable floor space. Parents can pull the trundle bed out at night as another sleeping space for siblings or sleepovers.
Some trundle daybeds resemble normal sofas and do not look out of place in living rooms. Some daybed makers hide the trundle behind faux-wooden drawers, making it difficult to detect the lower bed. For open-side daybeds, homeowners often hide the lower portion behind long comforters or slipcovers.
