Lovely chairs for a mid-century modern decor. Comfortable and appropriately sized with plastic levelling feet (so that all for corners contact the floor).
If I have one small gripe, it's that the leg assembly is not well thought out or planned for. It's really necessary to leave all of the bolts extremely loose until the chair is fully assembled. This is due to the fact that the holes in the legs that mount the center rail are not drilled at the correct angle (not even close). I have years of experience assembling furniture and machinery, and I can assure you that this is a design flaw that could be easily fixed.
That said, the assembled chairs are excellent and sturdy, and I wouldn't subtract a full star for the difficult assembly.
