small teat in vinyl, time consuming assembly easy but time consuming because three bolts at top of seat can only be tightened a small amount at a time only about 1/4 turn. Chairs also rock because they are not level. One seat had the mounting board upside down I had to drill new holes in it.

Pros: None look good in photos look cheap up close 
Cons: Hard to spend that much time on assembly with only 9 bolts per chair with allen wrench abour 20 minutes per chair.I hope they last a while but I don't think they will very cheap vinyl very thin.
