We bought these to go with a tall dark wood office desk.  They are gorgeous.  Easy to assemble.  We've had them for a year now, and the only thing is one of the screws that connects the legs to the ring is coming loose, likely because of how I sit in it, but it's easy just to tighten it again.  Only wish they were 2 inches taller for the desk.  They would have been 10 stars then!

Pros: Sturdy construction, beautiful details
Cons: needs to come 2-3 inches taller
