Purchased several months ago and was able to build it with two of my grandsons 8 and 6 years old. It is very sturdy. Only issue is the heavy duty plastic that holds the bars the mattress goes on. They are sharp and scratched my grandsons back leaving quite a mark as he tried to scooch over his brother. No roughhousing was involved. I plan to email the company to find out if they make some type of cover that goes over it even rubber pieces on the parts that are on the bottom and exposed. Otherwise it is exactly what we needed for our 8 grandkids under the age of 8.
