Seems pretty sturdy, but if you're thinking of putting it together alone, better think again. First tier was easy, second tier, OMG!

Aside from this got delivered to the wrong house, it doesn't come with post coupler. It is so unsatisfactory.

Easy to put together, seems very sturdy, flexible shelf heights, configurable, deep shelves, and great price.

Sturdy shelf. Easy to assemble. Good sized shelving units for basement storage. Have 3 of these from a couple of yrs ago and are holding up fine.

Easy to set up, except the second level of verticals. Another version had plastic braces to keep things together while assembling.

Clever design. Tooless assembly. Shelves are particle board. Steel corner posts and shelve supports. Excellent customer service. Would recommend,.

Great shelves but once again the vertical connector pieces are missing. Ill shop elsewhere next time.

What do you mean by "coupler not included". Where do you expect us to buy couplers? I cannot believe I missed these small letters.

Reasonable price, sturdy, easy to assemble. Vertical posts are 2 pieces each 3 feet long. They are held together by the middle shelf.

I would not buy this again. It does not come with the couplers/braces needed to join the unit together.
