I ordered this chair on Monday 11/18 and received by noon on Wednesday 11/20. Shipping was very fast and arrived in perfect condition. The chair is very easy to assemble and adjust. I thought the process of blowing up the ball would be daunting but it was simple as well, even included a hand pump and additional plugs. Make sure to pay attention to the recommended adjustment time frame. It does take your body some time to get used to sitting in a chair such as this. Don't assume that you will put it together then spend the whole day sitting in it comfortably. This is quite a comfortable chair but you do have to allow for an adjustment period, especially if you have a bad back like I do. If you spend a good amount of time at a desk or in a chair on a daily basis I would highly recommend purchasing an exercise ball chair as it causes you to participate in active sitting where as you are contantly making small adjustments and engaging your muscles while improving your posture and core strength.
I was assured by 3 different online customer services reps that I chatted with since the expected delivery date passed that I would be receiving my order, well, that was 15 days ago and still counting. I finally have given up, I don't even want the order anymore. I tried to get things taken care of once and for all today by requesting to cancel the order and get refunded - still no results. Now apparently I have to wait 1-2 MORE business days to get a response from a specialized customer care person to get this resolved.....hopefully. Not a great experience for my first order on Overstock.
