For thousands of years, humans sat comfortably without backrests, and so likely you can, too.

How to sit on a QOR360 chair
Sitting in one of our active chairs is quite different from a conventional chair. There are a few concepts that you’ll want to get right for optimal chair performance. Watch a short explainer video recorded by Feldenkrais teacher, Uwe Mester.
Why do our chairs look different from popular "ergonomic" office chairs?
It turns out that the "supports" provided by "ergonomic" office chairs confine rather than support us. By making it difficult to move naturally, conventional office chairs distort our posture and shift our metabolic machinery into idle. The result: worse posture, more back pain, and shorter lives. To make progress, we had to make a clean break with the errors of the past.
Why no backrest
Why no armrests
With your arms hanging comfortably from your shoulders and your wrists resting comfortably on your desk no further support for your arms is required.
Why no lumbar support
Lumbar support is all the result of a simple misunderstanding of our anatomy...

Size matters
Measure the distance from the ground to the top of your kneecap while standing. If you wear shoes when you sit, wear shoes when you measure. If your measurement is 21″ or less, you will need a Short chair. Greater than 21″ and you will need a Tall chair. There is some overlap in the sizes so don’t sweat it too much if you are right around 21″.
There are many reasons to switch to a QOR360 chair. Here are three.

MD DESIGNED
With decades of experience as a physician and researcher, Dr. Osler’s quest for a healthier way to sit led him to develop a better chair.

IMPROVES POSTURE

General
What is QOR360?
QOR360 designs and manufactures chairs that promote active sitting, helping to improve posture, core strength, and verall health. Our patented Red Rocker™ technology encourages constant micro-movements, reducing the negative effects of prolonged sitting.
How is a QOR360 chair different from a regular ergonomic office chair?
Traditional ergonomic chairs force static sitting, which can lead to back pain, poor posture, and poor health. QOR360 chairs promote active sitting with a seat top that gently rocks in all directions in response to the sitter’s posture, engaging core muscles, raising metabolism, and preventing slouching. Active sitting can help reduce back pain, and improves overall health through increased metabolic activity.
QOR360 chairs are designed without arm, head, or back rests, or conventional lumbar support. These “supports” actually make sitting posture worse, as your body relaxes muscles when relying on these unnecessary parts. With our simple mechanism, the patented RedRocker™, your body comfortably learns to support its own posture, strengthening your core musculature.
Who can benefit from a QOR360 chair?
Anyone who sits will benefit from active sitting! People who spend extended periods sitting may benefit even more from a QOR360 chair. Our chairs are ideal for home offices, workplaces, classrooms, and even kids who need an active sitting solution.
Is the QOR360 chair for home or office use?
Both! QOR360 chairs are great for office work, helping with movement while reaching and turning. They’re also ideal for home use—whether at a kitchen table, or in a home office. If you have to sit, make it active!
Chairs & Active Sitting
How does active sitting work?
Active sitting encourages small, constant movements that keep your body engaged, similar to walking. This helps improve posture, strengthen core muscles, and reduce back pain caused by prolonged static sitting. Learn more about active sitting, here.
What' sit like to sit on a QOR360 active chair and how should I first use it?
At first, people are often surprised by the movement, but quickly adapt and enjoy the experience. At first, start with 30 minutes at a time so you can ease into using the chair. Eventually most people adapt to using the chair full time within a couple of weeks! Everyone is different however and depending on your age and physical fitness you may adapt faster or slower. Active sitting keeps your core musculature engaged, improving posture naturally. Unlike traditional chairs, which can leave you stiff after prolonged sitting, QOR360’s constant micro-movements prevent that discomfort—so when you stand up, you feel ready to move, no stretching required.
Will it take time to get used to a QOR360 chair?
Yes, there is an adjustment period. Most users adapt within a few days to a couple of weeks. We recommend starting with short periods and gradually increasing your sitting time as your muscles strengthen.
Can I use a QOR360 chair all day?
Yes! Once your body adapts, a QOR360 chair can be used for an entire workday. Many users find it more comfortable than traditional chairs because it encourages natural movement. However we always suggest getting up and walking around every thirty minutes to an hour no matter what chair you are using.
Do QOR360 chairs work with standing desks?
The “Tall” sized Ariel chair has a max height of 27 inches, which is tall enough for some people to use comfortably at a standing desk, and many customers report using it in this way. However, our chairs are designed more specifically to use at a sitting height, so we find them a perfect complement to adjustable height desks by making it easy to switch between sitting and standing throughout the day.
Does active sitting actually burn calories? Can I useit to lose weight?
Active sitting increases your metabolic rate by about 20%, so over long periods, like the average 10 hours a day, active sitting can contribute to calorie burn which may help you lose weight. We're still studying how sitting durations impact results, but one guaranteed benefit is a stronger core and better posture, which can help reduce back pain and make moving more while you’re not sitting more easy and enjoyable. While active sitting isn’t a magic weight-loss solution, it’s the healthiest way to sit!
What is the science behind the QOR360 chair, and what physiologic changes does it produce?
Static sitting in conventional chairs leads to muscle inactivity and metabolic dysfunction, contributing to a cascade of negative health effects. When muscles remain still for prolonged periods, they become metabolically inactive, reducing calorie expenditure and altering biochemical processes. Research has linked prolonged static sitting to increased blood pressure, elevated fasting glucose, higher triglyceride levels, and cardiovascular disease risk (Biswas et al., Annals of Internal Medicine, 2015). Alarmingly, these metabolic harms are not reversed by exercise; even regular gym workouts cannot counteract the damage caused by prolonged passive sitting.
The QOR360 chair promotes active sitting, which continuously engages core and postural muscles, reducing spinal compression and improving musculoskeletal alignment. This dynamic movement may counteract the metabolic stagnation seen with traditional seating. Studies suggest that even small movements, such as fidgeting, significantly reduce the negative health impacts of sitting (Hagger-Johnson et al., American Journal of Preventive Medicine, 2016). While long-term research on active sitting is ongoing, recent studies show that the constant micro-movements encouraged by the QOR360 chair helps maintain metabolic activity, increasing caloric burn by 15%.
Purchasing & Orders

If it’s not the right fit, you can return it for a full refund. This is better than trying in a store because you get to see how the chair fits into your everyday life, and it usually takes a few weeks to experience all the benefits active sitting has to offer.
Do you offer a trial period?
Yes, we offer a 60-day return policy so you can try a QOR360 chair risk-free. If it’s not the right fit, you can return it for a full refund. We even pay return shipping in the continental United States, and it is free shipping to you, so there is zero financial risk.
What is the warranty on QOR360 chairs?
Our chairs come with a 3 year warranty. We stand behind our products and will repair or replace any defective components. Even if your chair has issues after that time frame, we are usually able to fix or replace parts for a minimal fee, reducing waste and making sure our chairs continue to help people for years to come.
Do you offer discounts?
We don’t run sales because we believe in working closely with our suppliers to keep our chairs as cost-effective as possible. We offer bulk discounts on orders of 5+ chairs and occasionally are able to sell lightly used or refurbished chairs at a 20% discount. Refurbished chairs have minor cosmetic flaws but are in perfect working condition. They are final sale but still come with our warranty for repairs or replacement parts.

Product Features & Usage
Do I need a cushion or padding with a QOR360 chair?
Our chairs are designed for natural, healthy sitting without extra cushioning. The firm seat helps your sitz bones provide the feedback your spine needs for proper alignment. Some users find it firm at first but adjust over time, similar to getting used to a bike seat.
That said, everyone’s different! If you prefer extra padding, you can slip a folded towel or foam (like a cut-up yoga mat) under the upholstery using the front zipper. We also offer optional comfort cushions for the Newton and Cleo 2. Feel free to customize your chair to fit your needs!
Can I adjust the height of my QOR360 chair?
Yes, all of our models, except for the kid’s ButtOn Chair, have adjustable height options to ensure an optimal fit for different users and desk setups.
How do I know which QOR360 chair is right for me?
We provide a detailed comparison guide on our website to help you choose the right model based on your sitting and workspace needs.
Do QOR360 chairs come in different sizes?
Most of our chairs come in “short” and “tall,” and most are height adjustable. Check our product pages for guidance on selecting the right size chair for you. [insert link to sizing video]
How do I choose the correct QOR360 chair size (height)?
The height of one’s chair is very important to allow you to take full advantage of active sitting. We recommend that you measure the distance from floor to the top of your kneecap (patella) while standing (in shoes you would normally wear while using the chair) and then pick the size closest to your personal patellar height. For a patellar height of 20in or less, you need a Short chair, if you have a patellar height greater than 20in you need a Tall chair. If you find yourself between sizes, it’s a good idea to choose the larger size. The fit doesn’t have to be exact, but you should select the chair that most closely fits your personal anatomy.
Why is the height of my chair so important?
Sitting with hips at a 90-degree angle often leads to slouching, collapsing the spine into a “C” shape, which can cause discomfort and back pain. To maintain a healthier posture, your hips should be slightly higher than your knees, creating an open hip angle and more natural spinal curve. That’s why QOR360 chairs are adjustable and come in multiple size ranges, ensuring the right fit for every user.
What is the weight limit on QOR360 chairs?
The Tilt!, Newton, Ariel 1.0, and Cleo 2 all have a max weight capacity of 250 pounds. The Ariel 2.0 is rated for up to 300 pounds. The children’s ButtOn Chair can safely hold up to 120 pounds and is NOT recommended for adults.
Should I buy wheels?
When you order wheels with your initial chair purchase, you’ll receive both wheels and stationary feet, which are easily interchangeable. You may also order wheels at a later date, if you decide you need them. Please note that while we offer wheels, we generally don’t recommend them as they can make active sitting challenging to get the hang of, and using them on a very smooth surface can be precarious. Most people assume they need them simply because traditional office chairs have always had them. But unlike bulky office chairs that can weigh 50 lbs, our lightweight 20 lb chairs are easy to pick up and move with one hand, making wheels unnecessary for most users.
Will using a QOR360 chair help with back pain?
Most users report relief from back pain after switching to an active sitting chair. While results vary, our chairs encourage healthy posture and core engagement, which can alleviate discomfort caused by traditional chairs.
Can children use QOR360 chairs?
Yes! The ButtOn Chair is designed specifically for kids to help them develop good posture habits early. Check our product page for recommended age and size guidelines.
Is the QOR360 chair environmentally friendly?
Our chairs, including the ButtOn Chair, Newton, Cleo 2, and seat base of the Ariel 1.0 and Tilt! are primarily made of sustainably sourced wood, and the cushion of the Tilt! is filled with all natural buckwheat hulls. While other components, like aluminum bases, natural rubber mounts, and polycarbonate rockers, are not biodegradable, our chairs are designed overall for minimal environmental impact and maximum durability. Each rocker uses about as much plastic as four milk jugs—but unlike milk jugs, they’re built to last a lifetime.
Care & Maintenance
How do I clean my QOR360 chair?
For wooden surfaces and performance leather, use a damp cloth and mild soap, if needed. For upholstered seats, a gentle fabric cleaner works well. Avoid harsh chemicals or abrasive cleaning tools.
Does my QOR360 chair require assembly?
Yes, but assembly is quick and easy—typically taking only a couple minutes with the included instructions. No tools are required.
Are replacement parts available?
Yes, we offer replacement parts for all our chairs. If you need a specific part, contact our customer support team by emailing info@qor360.com.
