Very easy to assemble. However, it is not as sturdy as claimed. Definitely cannot hold 250lbs. May be, it can hold 25lbs on each mesh. I tried to place a weight of 20kg on one shelf and I could sense that it is going deform permanently. Ideal for small amount of magazines, clothes, kitchen utensils etc, but not for heavy items. Don't cheat the customers with wrong specifications. If you are buying this to place a large amount of books, I suggest you to look for something else.
