Trundle Mattresses

Trundle mattresses are perfect for children’s bedrooms and guest bedrooms. When your little ones have a sleepover, a trundle mattress is ideal. You effortlessly store it under a bed, out of sight, and bring it out for guests when needed! If your child’s bedroom has limited space, a trundle bed mattress is the perfect way to utilise every inch of the room. It’s also the ideal solution for a guest bedroom. If you only have enough space for a single, it’s worth investing in a trundle bed.

What is a trundle mattress?

A trundle mattress is usually a thinner mattress that will fit onto a trundle bed frame and will also easily fit underneath a bed frame. We have a range of trundle mattresses here at Happy Beds, so whether you’re looking for memory foam, reflex foam or orthopaedic, you will find the right one. Find a mattress for your trundle bed here.

Can I use any mattress for a trundle bed?

A trundle mattress is designed to fit perfectly on a trundle bed, usually stored beneath a bed or guest bed. Due to the space requirements, you need to be careful about the mattress size to ensure it can be neatly stored in the trundle function of the bed when required. As such, you’ll need to buy a specific trundle bed mattress. Standard single mattresses won’t fit, so beware when making your selection!

What depth should I get for my trundle mattress?

There's no 'right' depth of trundle mattress that you should get; it entirely depends on how tall your trundle bed is and how much space you have to work with beneath your bed. As such, we sell the following trundle bed mattress depths:

  • 15cm trundle mattresses
  • 16-20cm mattresses

If you need some help measuring your bed to find out which size trundle mattress is right for you, look at our bed measuring guide for more helpful information.

What size mattress do you need for a trundle bed??

This completely depends on the size of your trundle bed! Our trundle mattresses come in a wide range of sizes to match whichever trundle bed size you choose. The trundle mattress size options include:

  • Cot trundle mattresses
  • Toddler trundle mattresses
  • Small single trundle mattresses
  • Single trundle mattresses
  • Small double trundle mattresses
  • Double trundle mattresses
  • King size trundle mattresses
  • Super king size trundle mattresses
  • European single trundle mattresses
  • European double trundle mattresses
  • European king size trundle mattresses

Can adults sleep on trundle mattresses?

Whether an adult can sleep on a trundle mattress depends on how much weight the trundle bed can support. Our trundle bed mattresses are designed to be just as supportive and comfortable as a standard mattress, making them an excellent choice for having guests stay. Still, the practicality depends on the trundle bed rather than the trundle mattress.
