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.

"No more back pain! I was desperate. I sit at a computer all day, and while all my coworkers with back pain converted to standing desks, it just wasn’t for me."


Features that make your current chair jealous...


Designed by a physician and researcher with decades of experience.


Easy-to-use adjustment knob. Simply unscrew and set to your desired height.


The Tilt! is one-third the weight of a typical office chair at only 13 lbs.


Tested to hold up to 250 pounds.


Less than half the cost of a typical office chair.


Just open the box and your Tilt! is ready to sit on.


One of the smallest chair footprints on the market.


Made with far less material than most modern office chairs.

We are onto something...


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

"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."




The Tilt! is designed as an ‘active chair’ and its unique design and construction make it more tippy compared to other QOR360 chairs and conventional chairs. This feature has been deliberately incorporated to promote movement and core strength for users. However, this could lead to potential falls if the product is not used properly.

The product may not be suitable for everyone. Individuals who are older, those taking medication that might affect balance, and those who generally experience difficulties with balance should consider their capabilities and circumstances before choosing to use the Tilt!. The use of this chair by individuals with the above-mentioned conditions could increase the risk of falling and severe injury.

It is the user’s responsibility to assess their physical fitness, health status, and skill level before deciding to use this product. All users are strongly encouraged to take time to understand how to safely use the chair and to gradually get accustomed to its motion.

QOR360 cannot accept liability for accidents, injuries, or damages related to the use of this product. By choosing to use this chair, you acknowledge and accept that you do so at your own risk.

It is strongly advised that users with the above-mentioned conditions consider our less-tippy Ariel 2.0.
