Trundle beds are special beds that are built low to the ground.
Young Children
Trundle bed is also useful in a guest room, or in any small space where you would like to have an extra bed. Some trundle bed frames are made so that the lower bed is on springs and can be raised to the same height as the upper bed. Two twin size trundle bed mattresses placed together are the same size as one king size mattress.
Different Sizes
Trundle beds are not just for young children. At one time, trundle beds were only made in small sizes. The top bed was a twin size, and the bottom bed was slightly smaller, making it difficult to find trundle bed mattresses that would fit the bottom. Nowadays, trundle bed can come in many different sizes. Full, King and queen size trundle beds are not uncommon, although the lower bed is still a twin size. This makes the trundle bed a most versatile piece of furniture for your home.
Trundle bed mattresses should be about 8 inches thick. Almost any twin size mattress should work with a trundle bed, but it can depend on the individual frame of your bed.
By doing so, you ensure that the bed will be level when both trundle bed mattresses are used at the same time.
