I bought this rack after moving into a new apartment with very little closet space. Right away it seemed very light and not solid at all, but I went ahead with setting it up because all the reviews on here were so positive. I loaded it up to capacity with tank tops and tees (all very light) on the main bar but did not use the extenders. It does not roll easily, and because it is so light, the swaying of the hung clothes tips the balance of the rack to the point where it could easily fall over.
About a week after setting it up, I began to notice the entire rack leaning to the left. Upon close inspection, the vertical steel bar that was (poorly, obviously) welded to the base was bending inwards and actually sinking, causing the entire rack to be off balance. I didn't put anything excessively heavy on the rack and am disappointed by the poor quality.
The description of this item states it would be ideal even for commercial use. Take it from someone who has worked retail for 5 years, this IS NOT TRUE. The quality of this rack cannot be compared to an industrial rack, such as those you find in the fittig room at department stores to hold go-backs. I recommend anyone looking for a truly high quality and heavy duty clothing rack that is built to last go elsewhere and spluge on a truly commercial rack, not this knockoff.
(Sorry for poor photo quality... these bars should meet at a right angle but the vertical one is oviously compressing/sinking the base and the welding is coming undone.)
