Trundle Bed

Whether you’re looking to save on space or you just want to put a stylish twist on an additional sleeping arrangement, you may want to consider a trundle bed. Modern trundle beds come in a wide range of styles and designs, but they may not be for everyone.


The term trundle bed refers to a hideaway bed frame and mattress, typically on wheels, that store away in the space under a main bed frame and mattress when not in use. Trundle beds come in various designs and sizes, with a full or twin pop up trundle bed being a fairly common option. Trundle bed frames and mattresses often come together as a set with the main bed frame and mattress. But trundle bed frames and mattresses can also be purchased separately and added to a standard bed frame, as long as there is enough space. Trundle beds are popular with children, especially for sleepovers or as an alternative for bunk beds.

The Pros And Cons Of A Trundle Bed

Trundle beds are a great way to add sleeping space without always requiring the space of a traditional bed. However, trundle beds do have a couple of small downsides that you may want to consider:

  • Because trundle beds are typically lower to the ground and have thinner and less supportive mattresses, they may not be suitable for long term use or for people suffering from pain or injury.
  • From a consumer's point of view, trundles beds that are purchased as part of a set or unit are typically more expensive than traditional beds. And, if you’re assembling it yourself, trundle beds are often more difficult and time consuming to put together than traditional beds.
