My chair is broken.

My home desk chair is slowly breaking down. The leather on the arm rests are cracked and it's getting very uncomfortable. I guess this means I'll be making a trip to the office furniture store. My biggest problem is that I tend to sit cross-legged in my chair at home so I need a wide chair that will accommodate my entire body. Yet it can't be too big or else it won't fit by my desk. And, of course, it has to be comfortable. The cushier, the better. There should be big comfy plush computer chairs. That would be nice.
