I got this as a sample, but I had been ready to buy these shelves. They were FAR heavier than I imagined and they are really heavy duty. They assemble without tools and they are sturdy. Everything is very well made and very heavy duty. It took about 10 minutes to put them together, and they are solid. I saw in the instructions tha they can hold 1000lbs. All my heavy items are on the shelves which are nice and deep. I 'm sorry I didn't buy these earlier. I just had no idea they were this nice.
