Bunk beds or double bunks are a fun way to make use of space in small rooms while the kids enjoy climbing up and down the ladder which is included, to get onto the top bed.
The top and bottom headboards / footboards are proportioned so that when our kids bunk beds are set up as two freestanding kids beds they look right. (like a bed - not half a bunk!) See our kids beds with the word "classic" in their name to get the picture.
A Double Bunk may be too high for your child depending on their age. In that case why not consider a Loft Bed which is safer due to the lower height.
