It is very sturdy, directions were extremely clear and easy to follow, good quality, did take us four hrs to assemble. 
My one complaint is that there is very limited space between the beds, which I guess should be expected with a triple. Also the standard two. mattresses fit very tight which make the beds very difficult to make!!! 
Overall pleased with this purchase, now to find a fantastic solution for bedding for a triple bunk that it easy and aesthetically pleasing!
