It would have been a great sturdy bed if the holes for placing the screws lined up appropriately. We ordered a twin size bed for my daughter. When we placed the leg extension pieces into the headboard they lined up perfectly on one side, we screwed them together but unfortunately for the other side the holes were about 1-2 millimeters off each, and we had to glue the pieces together. There was no way to screw the pieces together as the holes were misaligned. Also this bed frame is quite tall so definetly you need a box spring.
