I love these stools! I bought 4 and they all came preassbled and ready to go!
Shippping was quicker than expected.... 4 days earlier than specified. I didn't mind they came early as I live in Ontario! 
The only thing I was questioning was the colour of the base of the stools; I thought they were black but in fact are a grey shade! Not a big deal to me but could be to someone else! 
Overall love them!!
