Great chairs.  Gave 4 stars because the instructions for hooking up electronics are really vague.  However, the most difficult part of assembly were the arms, while trying to slide them onto the side of the seat.  The seat is so padded that it hangs over the side and obstructs the bracket that side piece sides into.  I finally came up with something that worked.  Take a wide, long piece of painters tape and tape it from the side of the seat, pulling it taught across the seat to hold it over so you can slide the arm bracket into the seat bracket.   Then just pull off the painters tape. The chair works well, looks great, and is very comfortable.
