This is a very cute bed and seems sturdy, but the box is missing four single support bars for the under side of the bed. This means that the mattress will not be fully supported. My husband and I had everything laid out and ready to build then we noticed the missing bars. Im pretty angry this was supposed to be a surprise for my son to wake up to - a big boy bed. I am hoping Wayfair or the manufacture can just send us the missing parts.
