After some serious labor of putting them together and tightening the bolts until my hands were red, They're actually well built chairs. I have about 15 years of upholstered furniture manufacturing in the near distant past. I know how products are made in the US, and how they're made in China. These chairs made in China may as well as have been made in the US. The chairs are really well made.

Instead of webbing in the seats, there's actually sinews springs. Big plus. The bolts used to put it together are of good grade metal. They probably won't thread strip. The staples used to upholster the fabric to the frame are heavy duty and actually come from an air compressed nail gun. Means it's durable.

Only down side? The grey and white is more of a cream/ecru off white.. Not the stark white as pictured.. 
Overall, after the frustration of assembling them, they're worth purchasing.
