Trundle Mattresses

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.

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!

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.

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

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.
