Similar to the ****** (Room Essential) ones I have, only much bigger. Make sure you put the leg levelers on first (mine didn't come pre-installed), so you don't do your shelf upside down like I did. Also, make sure you like where each piece/shelf will be placed, because if you don't, it'll take 2 people to remove it. Sturdy shelf and I have mine next to my much smaller Room Essential one in my guest room for storage (extra pantry). Satisfied with the price and amount of stuff it holds, but dissatisfied with the directions.
I purchased 4 of these sight-unseen based on good reviews and specs. When I was first putting it together I thought it was pretty nice. The leg poles are very sturdy and the shelves are good. What is NOT good is the way the shelves attach to the legs. These shelves are supposed to hold up to 250lbs each, but I found that the shelves were not that secure and they would easily start to slide down if you pushed on them or dropped something heavy on it near a corner. It might be ok for very light duty, but there are much better shelves out there with much better shelf attachment mechanisms than these. I returned them all.
It's not perfectly balanced, but no DIY shelf ever will be. But it's strong, adjustable, looks good, and functions. Very gruntled with this purchase.
