A white twin bed with trundle (sometimes called a trundle bed) is a “two beds on a” contraption – a bed frame and mattress can be slid or rolled under a bed frame slightly larger for storage when not in use. This allows an extra bed (stowed out of the way) when necessary, but also opens the door to other opportunities of storage and use
The most obvious use of white twin bed with trundle is its purpose – as an occasional extra bed. The smaller bed (the bed that gets below the main structure) usually has a relatively thin mattress and no box spring so you can fit in your room. This smaller bed may not be ideal for regular use.
White twin bed with trundle are more commonly twice the size, but some models have a bed frame bed with a twin trundle bed or two single mattresses – one of which appears next to the other with the rest of the main structure to form a king size sleeping space. For rooms that need occasional extra places, the nest can be a great space saver
Many people prefer to nest bunk beds, as trundles take up less space, but some bunk beds with trundle beds also come under the lower bunk – a good solution if neither a trundle bed nor bunk only provides enough space.
