When looking into the different types of available beds that can be used in guest bedrooms or in a child’s room, you may consider looking at the available types and styles of pop up trundle beds. The design of pop up trundle beds saves space by allowing for the trundle to be hidden underneath the main bed. With this setup, the main bed may either be used to sleep or sit on and the trundle may be pulled out as needed for additional sleeping area. Pop up trundle beds vary in design. There are simple metal-framed versions, wood-encased designs and daybed versions that can be used as a couch. When the trundle is needed it generally matches the height of the main sleeping area, allowing it to be used to create one large bed or two smaller ones.
