Trundle Bed Mattresses

Trundles are an excellent choice for a guest bed, but picking the right mattress can often be confusing. We've assembled answers to some of the most frequently asked questions to help make buying one easier than ever!

A trundle mattress is usually a thinner mattress that fits onto a trundle bed frame and allows it to slide underneath the main bed. These mattresses are the same as any other we sell, but our range has been curated to ensure they are not too high to cause any issues when the trundle is not in use.

There's no 'right' depth of trundle mattress that you should get; it entirely depends on how tall your guest bed is and how much space you have to work with beneath your bed. Double-check the dimensions of your chosen bed to see how much space you have to work with, as some will need a mattress that is no higher than 16cm, whereas others might be able to accommodate something a little taller!

Yes, you can use any mattress for a trundle bed if it is not so tall that it will prevent the frame from being slid back underneath the main bed. Our range has been specifically curated to make your buying decision easier. They are all under the recommended height and include plenty of popular options, such as contouring memory foam and supportive pocket spring, so you can find something to give your guests a comfy and restful night of sleep!
