I give it a one because it's designed for children, yet it's not made to withstand them! The slide started to detach after one month. The slide material is akin to dry wall, yet the screws do not attach with anchors, so the screws eventually get loose and slide out. We were able to reattach with longer screws, and those lasted a few months. Detached again, so we attempted to install our own anchors, which are holding for now, but we also had to use strong tape to keep the slide walls from splitting. What a pain! There are also some signs of cracking in the legs, which we reinforced with thick tape. So we are closely monitoring the safety of the bed. I doubt it will last a year. What a shame. Our five-year-old son really likes it, though.
