The healthiest way to sit.

The office chair you are sitting in is terribly designed. Modern chairs encourage poor posture and inactivity.

1. Relieve Back Pain

Active sitting keeps your core strengthened and body aligned. We are designed to move, and when you stay in motion, your back appreciates it.

2. Improve Posture

Posture is your body’s response to gravity. QOR360 chairs are designed to allow your hips and spine to tip, gently aligning into a natural, comfortable position.

3. Sit Healthy

Research shows that sitting is as bad for our health as smoking. People sit more than ever (Americans, on average, sit for 11 hours per day!) and it’s literally killing us. Active sitting keeps your body in motion, and helps prevent sitting disease.

"I’ve finally found something that leads to a sense of wellness, security, and freedom. Not only do I use this chair for normal sitting but am using it in movement exercises that I can conclusively say are restoring my functionality in a way that I never thought I would be able to."


"I love this chair. I was having shoulder issues in my previous chair from leaning and not being in an active position. This also contributed to some hip and ham string issues. With your chair I can still sit to take a load off but it keeps me upright, no slouching."



It’s a different kind of chair, invented by a former surgeon.

Former surgeon Turner Osler is trying to save the world from the traditional chair by creating a design that includes a rocking seat that feels more like walking than sitting. -Billy Baker


Your Office Chair Is Hurting You

But also, forget standing desks. Try ‘active sitting,’ according to a trauma surgeon who wants to cure sitting disease. -Ashley Abramson


Goodbye, Back Pain? This Office Chair Was Designed by a Trauma Surgeon

For decades, American workers have tried trendy office chairs hoping to alleviate the agony of sitting. Is the new ‘Active Stool’ the one? -Magdalena Puniewska


Customize your chair.

Choose from three different seat coverings and two different sizes.


Performance Leather (Vegan)

If you want to make a statement, here’s how. Elegant, buttery soft to the touch but nearly indestructible, our performance leather is stronger and far more durable than animal hide. And, unlike traditional leather, performance leather requires no upkeep. Maybe this is why Mercedes uses performance leather in their cars?


Corporate and understated, our upholstered Ariel fits easily into any office decor. But while it may seem undistinguished, beneath the seat is a radical sitting technology hiding in plain sight. Hand-stitched and with a thin layer of foam on the underside for breathability, we pay attention to detail.

Available in Gray.



(17-21 inches), for shorter folks


(20-28 inches), for average and tall folks

How to measure

How to measure:
Deciding the correct height of your QOR360 chair is very important to maintain proper posture when sitting. Our chairs are adjustable, but come in to overall sizes: Tall (20″ – 28″) and Short (17″-21″). To decide whether you need a tall, or short chair, stand in whatever shoes you will be wearing when sitting and measure from the ground to the top of your patella (knee cap). This measurement is roughly the height at which you’ll want to be sitting. So, if the height of your patella is above 21″ you’ll need a tall chair, but if your patella is less than 20″ your better suited for a Short chair. There’s some overlap in our chair’s heights, so if you’re patella is exactly 20″ you’ll likely be happy with either chair size.

Optimal workstation posture

Proper, comfortable posture will likely require adjusting the position of your work station. Here are some tips we developed working with specialists.

Love from happy sitters.

I received an email from my friend Larry Goldfarb, a well known Feldenkrais teacher/practitioner and Trainer in this method, he mentioned this new concept of sitting and mentioned he was using one of their chairs. Now imagine I was sitting on my solid oak stool at my computer in no real comfort but living with this as normal. Well I decided to take the hint and leap of faith and ordered a Ariel for my self. I have been using this wonderful chair for a little over a month now and what a wonder it is! I am so impressed with the engineering that has gone into this chair. It takes a little time to get accustomed to the sitting dynamics, but once you do, it gives a sense of freedom that is truly unique. I can’t imagine being with out this chair. If you are considering the purchase of one of these great chairs, just do it. You won’t be disappointed. Dave Worth PT GCFP

I live with a bleeding disorder that has led to arthritis in most joints in my body. I’ve had injuries from normal every day actions, including sitting down. Over the years, I have moved from the gamut of options in Western medicine to a more fluid journey into alternative methods of health preservation. I’ve tried many sitting devices to maintain neutral posture but have invariably been disappointed or hurt. I was recommended this chair by my rolfer whose opinion I really value. Combining the principals of structural integration and the mechanics of this chair, I’ve finally found something that leads to a sense of wellness, security, and freedom. Not only do I use this chair for normal sitting but am using it in movement exercises that I can conclusively say are restoring my functionality in a way that I never thought I would be able to. I hope to be able to adapt the principles of this chair and structural integration to help others like me who live with chronic pain some day.

I have sat on yoga balls, zero gravity recliners, stools, standing – and this is the first chair I’ve simply sat on and had it balance me. Best. Chair. Ever.


This chair is brilliant. Brilliantly simple. Really really expensive ergo chairs have managed to feel about there same as cheap crap office chairs to me, and standing desks add variety but don’t seem to add actual change in how I feel day to day. This is the first chair to have the balance and motion off a yoga ball without the high randomness and the pressure pushing at your backside. I can feel a difference after sitting on it at the office for four weeks now and I purchased a second for use at home. I’m also finally getting actual use out of an adjustable standing desk at work. The adjustable height desk is so much a part of there experience of this chair I adapted my home desk surface onto an adjustable height frame. Great chair. Thank you.

I love my new chair! My colleagues have all taken turns coming down to my office to try it. I’m a runner and have been struggling with some hip stiffness that’s affecting my back. Even after just a few days of using it, my IT band and psoas tightness is lessened. I was especially pleased with how easy it was to assemble, and in the overall quality of construction, especially at so affordable a price.


Better than advertised. As someone who practiced clinical medicine for many years but who transitioned to a phase in my career where I am at a desk quite a bit I was worried about the adverse effects of sitting so much. In emergency departments and clinics there were always rolling stools to sit on, but usually you’re so busy you don’t sit too much. The Ariel reminds me of those stools, but far better. I am very pleased with the way I can move, and adjust subconsciously while I type, video conference or read. Takes just a few days to get used to it, then you will never go back. I highly recommend it.

This chair has made a huge difference in my comfort and productivity in working at home. I recently sat in my office chair at work, and could not get comfortable or sit for a long period, which tells me this chair is really changing how I sit and engage.

Mikael Bristow

ABSolutely love this chair! I work from home and have had this chair for a few years. This IS my office chair despite me thinking I would have to switch back and forth with my old office chair:) No more back pain, better balance and tighter abs. Love it!


I wish I had found this chair earlier in my life! I’m at my home-office desk for 6-8 hours a day and found that this chair relieves pressure on my both my knees and lower back. It’s easy to adjust and after getting use to the “active sitting” I completely understand why it’s better for posture. Also, the sales and customer service team has been incredible to work with – very quick to respond to questions and helpful all the way through the process.
