Whatever you do, I wouldn't buy the Realspace Pro/Quantum from Office Depot. They may have since fixed the design, but for my current version:

The design for attaching the seatback to the base is poor - all that is holding it up is two metal plates attached to eachother at (about) a 60 degree angle with 2 screws. There is a "slot" one goes into but it is just plastic. Due to this the screws holding up the back have a tendency to snap in half.

Both of my screws broke after 1 month, causing me to go crashing onto the floor. They had a "recall" and distributed a repair kit with new screws but one new screw has already snapped for me. To really fix this chair they would have to do much more than distribute a new pair of screws. Hopefully they have in newer chairs, but I wouldn't risk $250 on it.

This may have to do with weight and height - I'm 6'4 and 190 lbs, so I would place much more stress on the screws than someone shorter. I still wouldn't risk it though.
