Let me start by saying these chairs look great! They are stiff and the back is a little short.  The bonus is the seat is deep so you can crawl up and be comfortable.  I am 5'5 and fit perfect.  My husband is 6'4 and it's on the smaller side but they are living room chairs.  The only thing I am skeptical about are the legs.  Not sure how they will hold up.  Seem a little wobbly but don't want to over tighten.
I got the dark grey/charcoal and its a nice deep rich color. Fabric is also nice.
