This ball chair is awesome. I've been using a yoga ball as a chair for quite some time now and if you think sitting on a ball with the cover is the same as sitting on a ball without one, then you have to try this product. Right out of the box you can feel a difference. I've now been using this one for a few days and I'll never use a plain yoga ball as a seat again.

The cover is very high quality and feels much more expensive than you would expect. The fabric helps hold you in place and keep you from sliding around at all. the handle makes it easy to move around without having to use both hands (important if you ever need to move it and your laptop from one side of the room to another. This is especially important if you use modular seating in your workplace.

I was curious to see if the stitching and seams on the ball would look symmetrical and I'm thrilled to see that they do. In the room, this ball looks more like a piece of art than a chair.

All in all, you can't beat the product for the price. There are other covered ball seats out there, but they don't provide near the value that this one does.

Update: I took the yoga ball out of the cover, was able to blow it up much larger, and can easily reach my keyboard and mouse now, so I will keep this one and just have it cover less..
When I finally got my office all to myself, it was past the return date for this yoga ball/seat. I blew it up, and sat down, and the seam with the zipper ripped (loudly) from one end to the other. Quite a disappointment. I had gotten the smaller one, and clearly needed the larger. The material seems really sturdy, and the ball was easy to put inside and blow up, so I'm giving it another chance, and hoping it was my error in judgement that was to blame. I'm ordering it again, bigger size, and using it within the return date!

Cover looks very nice /stylish, nice cover, took a while to pump it up, even though we used a foot pump"¦ was scared to blow it up ;) but worked well. Very comfortable, will work well for my PT prescribed Exercises.

Came with pump, inner inflatable ball, and the sheathing on the outside that you sit on. Just make sure you keep realigning the inflatable inside the sheathing as you pump it so that you don't have to deflate it to adjust it. I have only had to inflate it once, until I figured out how much inflation I needed. Does not lose air. If you need more height, add more air. Less height? let some air out. I am 5 feet, 5 inches tall, and I transitioned away from my hydraulic office chair, which I often changed my seating in throughout the day. Sitting on this balance ball has increased my core strength tremendously. When you sit down on anything, whether this balance ball or a chair, put the back of your index finger in the arch of your lower back; if that arch is not maintained when you go from standing to sitting, you need to re-assess your posture(try sitting on front/back of ball. middle,etc. until you find a combo that maintains that arch with the most minimal core or back muscle utilization so that you aren't having to focus on sitting. Your spine is strongest when you are upright and standing straight. The spine has curvatures in it that "by design", must be maintained; otherwise, you will shorten its longevity. We are constantly assaulted by gravity; might as well try to be healthy with your posture so that you don't spend your latter days in unnecessary, constant, back pain. In most cases, if you feel pain while sitting or operating a mouse/keyboard at the desk, don't just assume that is normal. Listen to your body and do research so that you can change whatever incorrect, 'offending' posture i hurting you. I strongly advocate the $15 Anker, USB side-ways mice; I have bought them for family and coworkers. They take a bit to get used to, but if you study 'natural position' and 'repetitive strain' injuries, you will see that being outside your body's natural position and having repetitive movements will end your computer career early, along with agonizing pain. "an ounce of prevention is worth more than a pound of the cure", so go ahead and spend a few bucks to save you money and inherit the priceless gift of health while you're at it, by taking care of your posture. If you say this balance ball doesn't work for you, keep in mind that proper sitting is a skill and takes time to understand. I am a drummer; it took me 3 years just to figure out how to sit down (on a drum throne). balancing 4 limbs, mind you. I could spend all day talking about posture because there is much on the topic; I only urge folks to take it seriously, and take the time to(learn how to) do it properly.

I liked the size of the yoga ball and the material of the cover is durable and easy to clean.The cover color is nice too! The handle on the cover makes toting it around very easy. The pump was easy to use and both inflating and deflating were easy both for use and storing.
