Bunk Bed Mattresses

Does a bunk bed need a special mattress?

Yes, UK bunk bed safety guidelines require mattresses that are 16cm or less in depth to ensure the guard rails are effective.

Mattresses for bunk beds taller than 16cm can be unsafe, especially for the top bunk. At MattressOnline, all our bunk bed mattresses are designed to be 16cm or under for safety and peace of mind.

What type of mattress is best for bunk beds?
