    Amazing software development chair

    Well designed chair that i am using for 9 hours a day while doing software development. The chair has a stiffer seat so I added a purple cushion for maximum comfort. The arms work well and are higly adjustable resulting in good support. Make sure that you adjust the height for optimal leg support. I have seen a 90% reduction is back and sciatica pain after purchasing this chair.

    Excellent for Posture

    As a person with some back pain, I decided to invest in something that I use everyday - my chair. As an office worker, it’s critical to have good support and comfort - this chair offers that. I’d recommend this chair to anyone who wants a chair that will make you feel almost weightless and comfortable or for those who need a chair designed to support good posture.

    Works for me!

    Initially I didn’t think this chair would work for me but then viewed the video to see all the available adjustments. The one adjustment that made all the difference was the ability to move the seat forward. It’s perfect now.
