So disappointed. These beds are essentially made out of cardboard. My 40 pound child fell through the bed before I could get the mattress on it! Absolute junk! The corners are NOT covered by a mattress as stated leaving 4 VERY sharp 90 degree angle edges. The number of bruises these beds (I bought 2) have caused is alarming. I covered the edges with a product meant to solve this problem, but they fall off as they won’t stick to the cardboard like beds. After less than a year of use, these junk beds are now superglued and duck taped in several places. My kids are NOT rough on them either. I wrote customer service to see what they are willing to do to remedy this. I’ll comment again if I can to update what response I get. I’ll be throwing these “beds” in the trash as they are not usable for safety reasons.
