Your body wasn’t designed to sit all day!
This chair is the result of years of research, prototyping, and testing to solve that problem.
Our unique Sit In Motion® technology acts like a swing to relieve crucial pressure points while providing lumbar support. Created by a chiropractor and industrial product designer, this is the first and only chair that can induce perfect posture and give you the freedom to move.
The seat height is 23.25″. The adjustable range is 19″–23.25″.
Maximum weight capacity 275 pounds.
While people of all heights have found our chair to be a great fit — everyone’s proportions are different! — we recommend that those under 5′4″ use a footrest for the most ergonomic position.
all33.com purchases come with a 60-day Guarantee unless otherwise stated at the time of purchase.
If you are not satisfied, you may return the item within 60 days of purchase for a refund of the purchase price. Please hold on to the original box until you are certain you are satisfied with your purchase.
Returns are subject to a $99 restocking fee ($199 for noncontiguous states, territories, and Canada).

If you do not have the original box, you will be responsible for return shipping costs, which vary by carrier.
It can take some time for your muscles to adjust to proper posture. We recommend you keep and use your chair for at least 10 days to allow your body to properly adjust because of the unique functionality of our Sit in Motion® technology. Please keep the box until you are confident you are satisfied.
If you still wish to request a return after 10 days, please call all33 Customer Support at (855) 223-6010. If you’d like to exchange your all33 chair for another, you must request an exchange within two weeks of your original purchase. Please note that once you request a refund, you have 10 business days to ship the chair back to us, otherwise it will not be accepted.

The human body was meant to move. Ours are the only chairs in the world that allow natural movement of the pelvis and all 33 vertebrae while you sit. This allows for good circulation all day long; blood brings your spine the nutrients it needs to stay healthy and your brain and muscles the oxygen it needs to keep your energy up.How It Works
If you sit all the way back in our chairs, there’s no way you can slouch. You’ll find your awareness of your posture increase even out of your chair, and the benefits of proper posture are endless: better breathing, optimal digestion, fewer headaches, improved mood… the list goes on and on. A happier, healthier you can tackle anything.See All Benefits

We’ve committed to bringing manufacturing back to the U.S so that we can ship your chairs faster and help people and the planet along the way. Our state-of-the-art facility is vertically-integrated to minimize our carbon footprint and keep workers safe and happy.
Plastic injection machines use 40% less energy than the norm to make our parts. Less energy in production, all to grant you more energy at work.
Raw materials are thoughtfully sourced or created in-house. The recipe for the foam in our cushions (a trade secret mix of water-based polyurethane) delivers Goldilocks-level padding that’s designed to fit with the chair's lumbar support and induce ideal posture.
From proprietary technology used in fabric cutting to minimize excess to repurposing materials like steel, aluminum, and plastic wherever possible, the guiding principle is to reuse & recycle.
all33 chairs are built using both cutting-edge robotics and the personal touch of real American workers. Our revolutionary design requires non-traditional production; for example, while other chairs use only machines to assemble seat cushions. The unique shape of our cushion calls for attention to detail — upholstery is fit around foam by hand and then a string machine pulls the drawstring around the cushion tight. All finishing sewing touches are handmade.
all33 chairs undergo the strictest durability, safety, and material tests in the industry. Our flagship BackStrong chair was developed and tested with the feedback of 1,000+ real back pain patients. The next step in all33’s evolution, the Axion, was refined using the feedback of 35,000 sitters.

I have been using this chair for about less than one year. I am cerebral palsy since birth. I can walk but limit distance, so this chair helps me stretch my muscles. I believe that!!
Comfortable chair with good lumbar support. I have nothing negative to say other than shipping took longer than anticipated. Plan for that and you have an excellent chair on your hands.
I purchased this 2 months ago. I've had lower back pain since sitting in a chair 10 hours a day during Covid. It has alleviated the pain. Great looking too. Highly recommend it.
