Wayfair worked with me to resolve an issue we had with the padding in one of the chairs. 
Definitely check measurements- we find that these are not very comfortable for the 6’3 220lb person in the house. Ideally the seat would be wider and longer. 
They are reasonably light weight to move around. Swivel is very smooth. The plastic caps on the feet don’t seem to be scratching the hardwood floors.
We have only had for a couple weeks— Padding is not very thick so I’m hoping that holds up. 
Aesthetic is great, I love the look and wish we could have these in a slightly upgraded quality but for now we are happy enough! 
I wish these stool designers would make a more comfortable foot rest, but that seems to be a common issue across-the-board!
