We also supply specialist mattresses for beds such as bunkbeds where UK safety legislation sets out a maximum mattress depth of 15cm. These mattresses can also be used in places such as day beds or occasional beds where you might not have room for a thicker mattress.
It is always important to check both mattress and bed frame dimensions before purchasing to ensure a proper fit.
