Alot of 5 tier shelves require you to use a shelf to create the middle connection, this version does not so you're not stuck working around a shelf directly in the center. Great unit, I bought two!
This shelf system is a great quality product. Setting up was easy, all the pieces were there and went together easily. It's very sturdy as well. This is in my farm shed to hold and organize my livestock feed. I'm able to fill up the shelves completely and none of the shelves bend, and the legs don't bow. This is a great shelf for any use you need it for.
I recently purchased 3 storage shelves from vevor.com. These are by far the best adjustable storage shelves I have ever seen. Very beautiful, adjustable, sturdy, easy to assemble.
These are commercial quality and I would highly recommend anyone looking for high quality beautiful shelves to purchase them. I will be ordering one more shelf to finish my storage area.
Just a very impressive product.
