I will update as to their sturdiness once I actually finish assembling them. Assembly is currently on pause as Wayfair sends more of the 55 mm bolts, as the holes where the 50 mm screws are supposed to go are too deep, and the bolts simply won't stay in. I had some misgivings after ordering these after reading some of the less favorable reviews, and it didn't help when the box arrived, announcing in bolt letters that I had ordered 'COULD GRAY" chairs. Attention to detail much? 
In any case, the color - more cloud gray than could, I would say - is lovely and I like the faux letter material and the wood finish. Small nick on the finish on one of the legs, but the wood itself is fine so I'll just fill that with a pen and it will probably be no problem. 
I have faith that once I get the right parts and finish assembling they will be nice chairs. I will update as to whether that ends up being true. 

Pros: Nice color and look
Cons: Needed more bolts, small nick to finish on legs
