Ordered these on a whim, and am not disappointed.  They do stack, but do not nest, if that makes sense.  Good, sturdy construction.  I emailed about weight limits, and was told they can withstand 1,000 lbs.  Doubt I'll ever test that out... but it's good to know.  Simple assembly with a folded towel and a household hammer to tap the tops in place.  

Pros: Durable, stackable
Cons: Might scuff up, but a bleach pen should fix that.
