Having the option of another sleeping space is sometimes vital in compact living, the Trundle Bed is compatible with a number of our metal beds, and is available in either black or cream. Constructed from steel, this frame has a mesh base which provides firmer support and allows air to circulate the mattress. When collapsed, the height of the trundle is 91 mm. The maximum height of the mattress that can be used is 200 mm with daybed frames, and 150mm with standard bed frames. Please note that when in the upright position, the trundle does not create a level surface for a double bed space.
