A trundle bed allows a person to have two beds in one, and they usually require a thinner mattress.

When not in use, people can place a trundle bed underneath a main bed, using less space and keeping it out of sight. However, due to this design, not all mattresses are suitable for trundle beds.

This article suggests five good quality mattresses for trundle beds.

A trundle bed is a low bed on rollers that a person can store underneath another bed, so people can stow them away when not in use.

This offers sleeping space for guests without the need for an additional bed.

Trundle beds can fit under several bed designs and types. They can fit under a traditional bed with an accompanying headboard and footboard, or under a bunk bed, canopy bed, or day bed that people may use as a couch.

Trundle beds offer space-saving properties, and people often use them as guest beds. They may also be suitable for children.

Trundle beds may work well in the following rooms:

  • guest bedrooms
  • children’s bedrooms
  • living rooms under day beds
  • studio apartments

Trundle beds are unsuitable for long-term use. However, they work well as temporary guest beds or in children’s bedrooms.

Due to their adjustable design, they are generally not as sturdy as a traditional bed and can sustain wear and tear over time.

Good quality sleep is important for a person’s health. An estimated 7–19% of adults in the United States are not getting enough sleep. Therefore, choosing the right mattress is vital.

Because trundle beds need tucking away, they often require relatively thinner mattresses.

Good quality thin mattresses can be comfortable and supportive. However, some thinner versions may not adequately provide the back support that people need.

If a person does not get adequate support from their mattress, they may experience lower back pain.

With this in mind, a person should choose a good quality mattress.

Here are five of the best mattresses for use on trundle beds.

Before purchasing a mattress, measure the trundle bed frame and the maximum height of the mattress that will fit under the main bed. A person can then choose a mattress according to these measurements, ensuring that it is a suitable fit.
