Multifunctional Trundle Beds Are Space Savers

Definition of a Trundle Bed

Some people ask us, What is a trundle bed?

A trundle bed is a two-in-one, space-saving piece of furniture. Like a bunk bed, it has both a top and bottom mattress. But a trundle bed allows the bottom mattress to be tucked away under the top mattress when it’s not being used for sleep.

A trundle bed’s bottom mattress platform is on casters or rollers, making it easy to pull in and out. Sometimes the bottom mattress sits in a trundle drawer.

Pop-up trundle beds allow the bottom mattress to be raised to the level of the top mattress, creating a larger sleeping surface. Pop-up versions are good for guest rooms, where two adults sleep together.

Perfect for Kids’ Rooms, Guest Rooms and Small Spaces

Trundle beds are ideal for guest rooms and for children’s rooms — or any room where you’d like to have additional beds for sleeping but don’t have a lot of space.

Unlike bunk beds, they provide a top mattress surface that can be used as a daybed. That makes them perfect for multipurpose rooms like dens or home offices that need to be used occasionally by houseguests.

Trundle beds also are great for large families with more kids than bedrooms. With the bottom trundle tucked away, kids have more room to play and do schoolwork.

Do you live in a small apartment or tiny house? Multifunctional trundle beds make the best use of limited space.

Daybed Vs. Trundle Bed

A daybed features one twin mattress that can be used for sleeping at night and for seating or relaxing during the day. You can think of a daybed as a cross between a bed, a loveseat and a chaise lounge.

A trundle bed has two twin mattresses to accommodate two sleepers. The bottom mattress can be slid under the top mattress (sometimes in a drawer) and secured until it’s needed again.

When the top mattress of a trundle bed isn’t being used for sleeping, it can function as a comfy daybed where you can read or watch TV. Think of a trundle bed as a bunk bed that takes up less space.

Traditional Trundle Vs. Pop-Up Trundles

There are two main types of trundle beds.

  • A traditional trundle bed has a low bed, on wheels or casters, that can be stored under a top bed, and pulled out for sleep. In a traditional trundle bed, the bottom mattress stays on the floor, below the top mattress.
  • A pop-up trundle bed allows the bottom mattress to be raised up to be the same height as the top mattress. This creates a larger sleep surface for two sleepers — more like a regular queen mattress.

Key Advantages of a Trundle Bed

  • Saves space
  • Versatile: Can be used in guest rooms, kids’ rooms, small apartments, tiny houses — anywhere you need extra sleeping space that doesn’t take up much space
  • Can be used nightly or for occasional guests
  • Daytime comfort: The top mattress functions like a daybed
  • Extra seating: The top mattress can be used like a sofa or chaise lounge

Are Trundle Beds Comfortable for Adults?

If you are comfortable on a twin or full mattress, you should sleep well on a trundle, which is a similar size.

If you like a bit more room, a pop-up trundle is a good choice. It raises the bottom mattress to the height of the top mattress to create a wider sleeping space.
