Yes, this chair can be assembled and used without the arms.
Very sturdy chair. Good if want Back comfort for sitting at extended periods of time. hope this Helps
The RealspacePRO Quantum/9000 chair is designed and manufactured to support body weight up to 250 pounds.
To help gauge fit based on your height, we recommend visiting a store and sitting in the chair. Take a few minutes to work the adjustment features also (especially chair height, seat back height & angle, lumbar support, and chair arm height & width). That way you can best determine if the adjustability ranges fit your body.
I am tall (6' 2") so I like the back in the highest position--the 5th click up. Which is another problem: I can't simply slide the back all the way up to adjust it, because all the way up is the release position and it slides back down. Instead, I have to carefully count 1-2-3-4-5 clicks to get it to the 5th position. This wouldn't be so bad if I didn't have to do this every time I got up and sat back down.
Hopefully there's a trick--or the manufacturer can come up with a better way to lock the back in place.
The chair back typically stays firmly in place while seated.
One idea is that you may need a bigger or more heavy duty chair.
The Quantum chair supports body weight up to 250 pounds.
If you weigh more, you will be more comfortable and supported in a big & tall chair.
I'm 6'1", 200# and the chair fits me just about perfectly. It's got a tag that says it's only good up to 250#. I think you'd find it too thin across and the fact it's just a mesh seat, not firm with foam would probably be a problem for weights over 250#.
This chair supports body weight up to 250 pounds.
We would recommend a big & tall chair for a body weight of 275 pounds.
There are a few upholstered options in our Thomasvile Style@work offer.
If you like Mesh, you might like one of these....

A big & tall chair will fit your body dimensions and weight more comfortably and give it the support it needs throughout the work day!
Thank you so much!
I tried one in the store (without any directions) and it seemed that both tilted at the same time, so I couldn't tilt the back without tilting the seat, etc. Also, I could only get it to lock in a few positions--level, and tilted back.
Thank you for the quick answer. I bought the chair but I can't get the back tilt to infinitely adjust. When I loosen the Tilt Lockout handle, the back does tilt to any position. But when I lock it, it snaps in one of only three positions. Am I doing something wrong or is that the way it is designed?
Unfortunately, the back and seat do not tilt independently. The "synchro tilt" feature means the seat tilts back a little as the back tilts back. Worse, there are only 3 positions: back near vertical, back slightly tilted back, and back tilted way back. (With seat tilting at the same time). If one of the first two positions fits you, it's great. But if you need a slightly different position for the best ergonomic fit, you are out of luck.

I'm wondering if this is the same chair, or if they have fixed the design flaw?
Yes. The manufacturer, in cooperation with Office Depot, initiated a voluntary recall in October of 2009. As a result, the chair was enhanced. Presently, the Quantum Realspace PRO? 9000 Series Mid-Back Multifunction Mesh Chair, Item 510830, sold by Office Depot is the manufacturer's new design.
