This bunk bed is perfect for my 3.5- and 5.5-year-olds!  They really love it! It is so sturdy and it was easy to build. It took about an hour with the kiddos "help."  The finish is flawless and the ladder is sturdy. You can easily clip a fan or a ouch to the edges for storage on the top bunk. The upper safety rails are perfect for keeping our kids safe. There is a perfect amount of space between the two bunks, but also still between the top bunk and the ceiling (I can sit up top without ducking).  All around it is a great bed and I would highly recommend it!
