You've got questions, we've got answers

A uniquely shaped rocker (the eccentric bicylinder) sits just under the seat of every QOR360 chair. Because this rocker is curved on both its upper and lower surfaces with the curves at right angles to one another, this rocker allows the seat of a QOR360 chair to tip in every direction. So, while the geometry of the rocker is simple, the healthy motion it encourages is quite sophisticated.

If you purchased an adjustable chair, arrange for the seat top to be even with the top of your kneecap.

The height of one’s chair is very important to allow you to take full advantage of our active chairs. We recommend that you measure the distance from floor to the top of your kneecap (patella) while standing and then pick the chair with a height closest to your personal patellar height. 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.

All adult QOR360 chairs that are shipped within the United States come with a money-back guarantee. If you don’t like it, simply return it to us within 60 days and you will get a full refund. We even pay return shipping! This offer does not extend to the ButtOn chair for Kids or any adult chairs shipped outside of the United States.

All our chairs come with a standard cushion made from closed cell foam in red or black, it provides comfortable padding as well as a bit of traction because our wooden seats are smooth. Most find this to be enough, but some want some extra comfort so we also sell our Deluxe Cushion additionally that is thicker and offers more padding. Made from high density memory foam, this is the answer for those who like some extra padding.

We believe all our QOR360 chairs provide active sitting that both attractive and affordable. We think you’ll be happy with any of our models. Choose the one that seems to speak to you.

We provide free shipping for all QOR360 chairs, but to help control cost, we ship QOR360 chairs in the smallest box possible. Most models require a bit of assembly, but we’ve worked hard to make this easy and intuitive, and we provide written instructions. Assembly should take only a couple of minutes for any model of QOR360 chair.

To ensure that QOR360 chairs are as affordable as possible we decided to sell the QOR360 directly over the web, an approach that avoids the substantial markup in price added by furniture retailers to ensure themselves a significant profit margin. Our direct marketing approach makes it difficult to try out a QOR360 chair. This is why we offer a 60 day trial period. If you aren’t completely satisfied with your QOR360 chair, simply return it to us for a full refund.

People spend a lot of time sitting at work, so we believe this is a great opportunity for people to be sitting better, accruing the benefits of active sitting. On a practical level, we also think the QOR360 chair makes a great task chair for the office because it facilitates reaching and turning. But because people do a lot of sitting at home as well (computer time, TV time, etc.) having a second QOR360 at home may make sense for some people. And, of course, a home office is a great opportunity to sit actively. “If you have to sit, get something out of it!”

Most conventional chairs have a seat height of 18”, a height which is designed to ensure a “90 degree, 90 degree, 90 degree” (ankle, hip, knee) posture for most people. While the ankles and knees are fine at 90 degrees for prolonged periods, sitting with the hips at 90 degrees has the unfortunate effect of causing most people to slump forward at the low back, collapsing the “triple curve” architecture of the spine into a simple “C” shape. However, this problem is solved by sitting with the hips at an angle that is greater than 90 degrees:

Changes in the curves of the back:
a. Typical Seated Posture (“90/90/90”)—note “C” shaped spine
b. Perch Posture—curves more like standing posture
c. Standing Posture—note normal “S” shaped spine

Although the lumbar spine is quite flexible, the sustained loss of the normal convex forward curve of the low back (“lumbar lordosis”) quickly makes sitting uncomfortable and has been implicated as the origin of low back pain.

To avoid the loss of the lumbar spine’s normal lordosis it’s important to adjust sitting height to ensure that the hip joints are 3 or 4 inches higher than the knees. This requires that taller people have taller chairs and that shorter people have shorter chairs, something that seems obvious in retrospect. For this reason, QOR360 chairs are not only adjustable but come in two size ranges: 17” – 21” and 20” – 27”. The QOR360 chair that is not adjustable (Juno) comes in three sizes.

Your QOR360 chair has only a single moving part, the eccentric bicylinder held in place by four very tough vibration isolation bobbins (motor mounts), so nothing is likely to wear out or need adjustment. In the three years that we have been continuously testing our chairs no component has required attention. However, in the unlikely event that your chair ever requires some sort of fix, please return it to us and we’ll repair or replace it for free.

Because the QOR360 has only one “moving part” its mechanism requires no upkeep or adjustment. We do recommend checking the motor-mounts for wear once a year, but we doubt that they will ever need replacing.

Active sitting is new to most Americans, and so, although the problem you suggest hasn’t to our knowledge actually happened, it is likely that sooner or later someone will have an unpleasant surprise. We recommend that if possible everyone new to active sitting have a ten-second explanation and perhaps demonstration. If you’re sitting on a QOR360 chair for the first time by yourself we suggest that you place the back of the chair four of five inches from a wall to foreclose the possibility of falling backward.

A primary component of QOR360 chairs is that most ecofriendly of materials, wood, a material that is both sustainably produced and biodegradable. Unavoidably, a few components of our chairs are not biodegradable. For example, the vibration isolation mounts that attach our rocker to our chairs are made of natural rubber; there are only four of these per chair, however, and they are quite small, so overall they have a small eco-footprint. The rockers in our chairs are injection molded from a very tough plastic, polycarbonate. Although this plastic is produced from petroleum, a carefully engineered structure of internal ribs allows us to make very strong rockers using a minimal amount of plastic, thus controlling both cost and environmental impact. One of our rockers contains about as much plastic as four one-gallon milk jugs, but, unlike milk jugs, our rockers will last a lifetime.

When people first encounter the QOR360 chair there can be several different reactions, sometimes all at once. Surprise is common, as is amusement, perhaps because the expectation of a “solid” seat is challenged. After a moment of disorientation most people “get it”: they catch their balance and sit up in a tall, balanced posture and then begin to explore different modes of rocking. Kids, on the other hand, seem to simply enjoy the ride without trying to figure out or explain the experience.

The first time you sit down on a QOR360 chair we recommend that you place the back of the chair 4 or 5 inches from a wall, to preclude the very slight possibility of falling backward. After a few moments to get over the initial surprise of active sitting sit on your QOR360 chair anywhere you wish, you’ll be fine. Sit playfully, confident that your spine knows its business and will find and express your naturally perfect posture.

Many people report that sitting on a QOR360 feels like they’re floating. Because your posture is constantly changing, adjusting to small changes in the angle of the seat, your spinal reflexes are constantly adjusting your spinal musculature to optimize your posture. All of this activity takes place outside conscious awareness, a silent conversation between your spine, its muscles and gravity.

Another thing often reported by our testers is a profound difference in how they feel when they get up after prolonged sitting: After sitting on a conventional chair many people find that getting up leaves them with a feeling of stiffness in the low back and pelvis, an uncomfortable feeling that requires stretching and bit of cautious walking to set right. This “locked spine syndrome” doesn’t occur even after prolonged sitting periods on a QOR360. Because the active sitting provided by the QOR360 keeps your spine in subtle, continuous motion your spine never becomes stiff from the inactivity that is enforced by static sitting in conventional chairs. So, when you get up from sitting on a QOR360 chair, well, you just get up and get on with your day, no stretching or limping required.

To begin with, be sure that the seat of your QOR360 chair is high enough; the seat of most Western chairs are only 18” above the ground, too short for most people. This forces folks to adopt an unnatural, slumped, posture in their low back rather than the naturally elegant ‘hollow back’ (lumbar lordosis) that is the spine’s preferred configuration.

Start by sitting on your QOR360 with a basic, balanced posture: feet flat on the floor shoulder width apart, sitting bones perched in the middle of the seat just above the RedRocker™. Your head should be balanced atop the spine, with the jaw bone parallel to the floor. Of course, all this will change once you do a bit of rocking, but it makes a good starting point. So, sit playfully, confident that your spine knows its business and will find your naturally perfect posture over your first few minutes of active sitting.

The active seat of every QOR360 chair allows and encourages controlled movement in every direction in a way that is simple and unencumbered. The QOR360 chair follows every movement of your body, resulting in a natural sitting position that supports and encourage your moment to moment movements. Additionally, because reaching, leaning, twisting are all facilitated, the QOR360 chair turns out to be an excellent task chair for office work as well as other pursuits.

Epidemiologists have known that static sitting is bad for people for some time now, and it’s become clear that static sitting on conventional chairs causes at least two different sorts of problems.

Sitting in conventional chairs requires that anatomically unusual postures be held for protracted periods, postures that can cause stiffness and contribute to back discomfort. Additionally, the core muscles are put at rest by static sitting, leading to deconditioning of these muscles that sets the stage for back injury and chronic pain. An interesting series on National Public Radio explores some of these problems.

2. A second problem with conventional chairs is that sitting in these chairs causes most of the muscles in the body to “go dark”, that is, become metabolically inactive. This results not only in a decrease in the number of calories used, but a fundamental change our basic biochemistry, resulting in deleterious cardiovascular and metabolic effects: increased blood pressure, increased levels of fasting glucose, triglycerides, and high-density lipoprotein are all associated with static sitting. Indeed, in epidemiologic studies sitting still has been shown to be associated with increases in all-cause mortality and a host of other medical problems including cancer (Biswas et al. Sedentary Time and Its Association With Risk for Disease Incidence, Mortality, and Hospitalization in Adults; Ann Intern Med. 2015;162:123-132). Discouragingly and perhaps counterintuitively, the metabolic harms caused by passive sitting are not reversed by periods of vigorous activity; going to the gym will not undo the harm of passive sitting.

There is some good news, however: it turns out that even modestly increasing the amount of activity involved in sitting may have large benefits: a recent study found that those who simply fidget while sitting are largely protected from the harmful metabolic consequences of sitting. Study. (Hagger-Johnson, Sitting Time, Fidgeting, and All-Cause Mortality in the UK Women’s Cohort Study. Am J Prevent Med; 50:154, 2016). Although it will require long term studies, we believe that the increase in seated activity provided by the QOR360 will provide important long term health benefits.

“Supports” provided by conventional “ergonomic” chairs actually prevent your muscular support system from freely expressing itself. Unfortunately, over time static sitting leads to a weakening of the core musculature, a situation that actually makes it difficult to sustain optimal posture. A downward spiral ensues with ever weaker core muscles requiring ever more support when sitting. The QOR360 chair breaks this cycle by subtly engaging the core muscles while sitting. Although reconditioning may take a few days to a few weeks, typically people are comfortable sitting all day on a QOR360 chair within a few days.

Yes, but for many of us who are badly deconditioned from a lifetime of sitting in conventional chairs a period of adaptation may be necessary. Typically, a few days is all that’s required to acclimatize to a backless chair, but for some people, a few weeks may be necessary.

Active sitting is more, well, active, than passive sitting. We recommend that those new to active sitting work up to sitting for a full day on a QOR360. Depending on how conditioned one’s core is this period of acclimatizing to a QOR360 chair may take only a day or two or as long as a week or two.

The surface of the QOR360 seat is slightly curved to allow front to back rocking without compressing the muscles of the upper leg (biceps femoris) or of the buttocks (gluteus). The human pelvis is an engineering marvel. Not only does the pelvis allow the spine to balance directly on the femurs (leg bones) while standing, but the pelvis also provides a sort of “kickstand” on which we can balance while sitting. Called the “sitz bones” (or ischial tuberosities), these two bony prominences are located at the very bottom of the bony pelvis, one precisely beneath each of the femoral sockets. This arrangement allows the legs to rest while the entire weight of the upper body is transferred directly to the sitz bones. Importantly, when we sit on the sitz bones the upper body can use the same reflexes to stay balanced and comfortable that it uses while standing. The slightly curved seat of all QOR360 chairs facilitates perching on the sitz bones. Sitting directly on the sitz bones not only provides clear input to the reflexes required for natural posture, but also facilitates rocking by allowing the pelvis to tip forward and backward without compressing the biceps femoris or gluteal muscles, gently flexing and extending the lumbar spine.

The word “ergonomic” is often applied as a “marketing tactic” by various seating companies. The term is applied to static structures that support the back, neck, spine, etc. Unfortunately such “support” forces one to sit in a single, non-active posture which fails to support natural spinal movement and health. QOR360 takes a radically different approach, with true ergonomic seating that promotes continuously subtle and healthy movements of the vertebrae.

An exercise ball provides a fundamentally different type of motion than the QOR360 chair because the ball allows the pelvis to translate through space. The QOR360 chair, by contrast, allows the pelvis to tip in all directions, but does not allow translation. Unfortunately, the exercise ball allows one to sit in a slumped posture, losing the natural convex forward bend of the lumbar spine.

This slumped posture is hard to arrive at on a QOR360 chair, and even harder to maintain. Furthermore, the exercise ball height is hard to control, as it depends on not only the size of the ball but the inflation pressure. The QOR360 chair provides precise control of the height of the chair. This is important, because the angle formed by the femurs (leg bones) at the hip joint determines whether the lumbar spine is free to assume its natural curve. Read more…

All QOR360 products are designed to promote active sitting instead of static sitting. Also called dynamic sitting, active sitting refers to the idea that your spinal reflexes are free to adjust your posture from moment to moment while in a seated position.

Unlike static, conventional chairs, active sitting is the concept that flexibility and movement while sitting can improve posture, core strength, and be beneficial to the human body. You can read more about active sitting here.

Yes, yes, and yes. Because the active sitting allows your spinal reflexes to naturally move and adjust, most users find that their posture immediately improves when they sit down on a QOR360 chair.

Moreover, because the active sitting gently and continuously conditions your core musculature this improved posture over time becomes habitual. Slowly and gradually, active sitting can condition core muscles that may have been ignored in your day to day routine of sitting in a fixed position. Active sitting has been shown in studies to increase your metabolic burn by up to 15%.

Why “Ergonomic” chairs are bad for your posture.

Why “Ergonomic” chairs are bad for your posture.

Most people rapidly acclimatize to the QOR360 chair, and within a few days sitting on a QOR360 chair seems normal. Indeed, sitting on a conventional chair can seem surprising, feeling dead and unresponsive compared to the QOR360 chair.

Sitting becomes more interesting, and more fun, when it’s active. Additionally, posture is improved when your spinal reflexes dictate your posture rather than your chair. Finally, active sitting improves metabolic parameters, a change that likely provides important long-term health benefits.

Although the research is not yet available, we believe that the increase in activity while sitting afforded by the QOR360 will provide important long term health benefits.
