I’m very happy with these chairs! The seats are more firm but I think they’re comfortable. Assembly involves attaching each chair leg with three screws. I ran into one one screw hole that caused a few screws to strip, which meant I couldn’t fully assemble the chair. Wayfair quickly sent me a free replacement set and I didn’t need to return the old set. Fast shipping. I used Scotchgard and didn’t notice any color change.
