Partly yes, mine is a bit deep and a bit wide. The seat angle is good, but these chairs put you leaning back anyway, so you don't really need much of an angle between the seat and back. I think I had mine at 5 degrees, and it was too much, given the already steep angle of the seat. I reckon you could go back square to the seat and it would be very comfortable.
I gave mine a nice rounded front and that was good, as well as wide arms for a glass of wine. I also made the back fan hollow across its width, rather than flat, and that was very comfortable.
