To call the box that the K Series comes in large might be an understatement. It is as tall as a TKL keyboard is long and when you view it from the top it dwarfs the keyboard. The box weighs a total of 70 pounds as well so your delivery guy/girl isn’t going to be a fan of you when this comes in. Once you maneuver the box inside and get it opened up you will find the chair back and arm rests right up top. The armrests come attached to the chair base but you can expect to have to work to get the chair back out from in between them. With the main pieces of the chair out, you will see that the chair was sitting in a foam tray with plenty of padding. There is a box of accessories along with the other important pieces of the chair. The base is also slipped in between the chair back and the chair bottom, keeping it protected as well.
