I like these stools a lot so far. They're solid but light, have clean looking welds, are pretty square and straight, and the wood has great character (without being overly 'rustic' looking). Today I worked at home and sat in one for basically hours on end - no complaints. I think the slight dip in the seat actually makes a different there.

My only complaints are: the height of the cross brace and the material of the adjustable feet feet. I'm 6' and the brace is just a little higher than is ideal for a foot rest. The feet are plastic and will undoubtedly need to be replaced with felt pads someday. Neither is a deal-breaking issue though.
