Maximize Your Energy Potential
Feel Good, Work Well
MORE MOVEMENT = MORE ENERGY
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
GOOD POSTURE = GREATER PERFORMANCE
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

Built with Care in the USA
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.

— Daniel R.
GREAT for your back!
“I have to say was a little skeptical about purchasing a chair for $700.00! I always like to try them out first. I took a chance, glad I did. The BackStrong C1 has to be the BEST computer chair I have ever owned. Shipping was fast...arrived in (5) days. Assembly took around 8 minutes. Then I sat on it...WOW! GREAT back support. Highly recommended!”
— Rich G.
Great office chair!
"I never thought I'd buy an office chair without trying it out. But everything about this chair seemed right, so I bought it. And I love it! It gives me amazing low back support and the movement keeps me from getting stiff."
