With no extra bedroom, sometimes it's hard to find a place for guests to stay. If you don't want or need bunk beds and don't want to put grandma on the couch, a popular option is a trundle bed.

A trundle bed is basically just a twin size bed on casters that rolls out from under a regular twin size bed or a daybed. When not in use, it can simply be rolled under the bed, hidden behind a dust ruffle and forgotten about until another guest arrives. Much like the old-style Murphy beds, this is a true space saver.

Daybeds

The most popular style of trundle bed is the daybed. Although you can purchase a daybed without a trundle, most people opt for the trundle to provide extra sleeping space in their home. Trundle beds can also be purchased on their own to be slid under any regular bed.

Some trundle beds look like part of the bed. For example, a popular style is a bed that looks like a captain's bed and the trundle is hidden behind a faux drawer panel under the bed. It just slides out like a drawer to provide that extra sleeping spot.

There are many online resources for trundle beds, some of which provide purchasing advice as well as have trundle beds for sale.
