How is the CoreChair different from other ergonomic chairs?
Traditional ergonomic office chairs focus more on providing relaxed support and typically commit the user to a one fixed position that diminishes healthy movement. Similar to a lounge chair, a traditional chair allows the body to settle into a reclining position which in most cases results in poor alignment of the user’s body relative to their workstation.
CoreChair promotes optimal sitting posture because it embraces the pelvis with an aggressively shaped seat complimented by snug support at the top of the back of the pelvis, near your belt level. With the pelvis supported in this manner, the user experiences a natural balance of their spine from their pelvis to their head. Most people using traditional chairs either perch on the front edge of their seat or completely slump into the tall back, causing excessive demands on their musculoskeletal structure.
CoreChair provides a pivot point immediately beneath the users’ center of balance which provides natural movement in all directions up to a safe range of 14 degrees.

What can I expect after sitting in the CoreChair for a few weeks?
Most people immediately transition to the intended comfort and ride of their CoreChair and experience little if any side effects. For some, they will notice the results of this new and improved sitting position and the added movement, much like they might after their first few visits to the gym on a new exercise program.
Because the chair positions the user to sit taller and assume an ideal posture, the supportive soft tissues of the core begin to reprogram to accommodate this. For those who have realized this initial perceived discomfort, the vast majority report that this discomfort resolves within a few weeks. For persons who have a chronic back issue arising from a diagnosis such as a herniated disc, strained soft tissues, or similar, the reported feedback in most cases is that the position and movement provide very quick relief.
In the therapeutic world “motion is lotion”. There are some individuals who have more significant back issues and have been seeking a solution for quite some time. While CoreChair is an excellent adjunct to a more traditional therapeutic treatment, it should not be considered an alternative. At CoreChair we encourage a variety of working positions throughout the day, from sitting to standing and walking opportunities.
We also encourage preventative and therapeutic complementary solutions such as yoga, safe training, and massage as well as physiotherapy and chiropractic care.
Is it an orthopedic chair?
Yes. CoreChair is designed to provide an ideal combination of optimal support and positioning with safe movement. It can be a perfect orthopedic intervention, supplement to other health care initiatives, or even preventative measures. In contrast to traditional sitting solutions, CoreChair encourages healthy movement which is necessary to provide ideal nutrients to your supportive soft tissues (muscles and ligaments). CoreChair has proven to be a very effective contribution to persons with chronic back pain.
Why are there no armrests?
With armrests, most people have a tendency to introduce chronic leaning as part of their sitting habits. Armrest dependency increases static lateral positioning of the spine and places unnecessary pressure on the forearm. CoreChair promotes more natural and balanced positioning of the spine. The resulting stability and supported position mean there is no need for armrests.
Will CoreChair allow me to burn calories while I sit?
“Sitting disease” has more to do with not moving than just sitting. When you do not move, you do not burn calories and your metabolic system becomes challenging as it requires movement to regulate your glucose production and vascular reactivity. Calorie measuring is a very simple method to measure work.
A recent Mayo Clinic study found that passively sitting on a CoreChair at least resistance results in an increased caloric expenditure of 20% over sitting in a traditional chair that does not encourage movement. When the user engages in specific exercises designed for use on the CoreChair, the user can expect a caloric expenditure of 150% or similar to walking at approximately 2 mph.
Mayo Clinic promotes its NEAT program (Non-Exercise Activity Thermogenesis) and the fact that you don’t have to engage in excessive exercise to burn calories but that subtle and continuous movement throughout the day, will result in the type of metabolic stimulation to enhance your bodily functions.
Will I get tired if I sit in the CoreChair for too long?
Many people who have endured long periods of time on an exercise ball as a substitute for their office chair, will share that they feel fatigued over time. This is mostly due to the fact that in order to maintain an ideal sitting posture, they have to engage their core muscles at a high level, continuously. This is exhausting and eventually fatigue sets in.
On the CoreChair, the pelvis is embraced and rendered in a neutral posture. This alleviates the need to over-engage your core. This pivot point on a CoreChair is directly beneath your center of balance. So with your pelvis and your thighs supported, and your feet stable on the ground, we have a very stable three-point base of support. Another misconception is that we might get tired from moving.
In fact, when we don’t move and don’t get optimized blood flow and the supply of oxygen and nutrients that accompany this blood flow, that is exhausting. When we assume a slumped sitting position, we also collapse our thoracic cavity that houses our critical internal organs. This, in turn, reduces what is known as our ‘vital capacity or the volume of air that we can pass through our lungs, which further affects the oxygenation of our blood.
Will CoreChair really strengthen my core?
While the CoreChair is not as unstable as an exercise ball, it does engage your core stabilizing muscles very much on par according to a study conducted by the Dept of Kinesiology at the University of Waterloo.
When we collapse into a traditional chair, which may indeed feel comfortable, our core stabilizing muscles are too relaxed and tend to approach atrophy or muscle wasting. Continuous low-level stimulation of these critical stabilizing soft tissues will definitely add to your core strength and you can expect a carryover effect to your other daily activities.
What is it like to sit in a CoreChair?
Reports arising from thousands of CoreChair users suggest that they feel:
More alert and productive throughout their workday:
• Less stiffness in their hips and low back that they would normally experience when they stand up from a traditional chair after sitting for a period of time.
• More comfort under their sit bones and tail bone
• Reduced upper back and neck pain
• Less strain on their back when reaching
Why is the back so low?
CoreChair is designed to embrace the user’s pelvis in an engaged sitting position and is not intended to be a lounging chair. When properly seated, users do not need a tall back.
In fact, the upper portion of the tall back is not used by most users, except when reclining. Sitting on a flat level surface with a flat back tends to promote slumping, where the pelvis tilts backward.
Traditional chair designs introduce lumbar supports in an attempt to correct the resulting flattened low back. This only addresses the symptom of slumping whereas CoreChair’s pelvic stabilizer addresses the cause by supporting the pelvis and reducing the slumping and low back flattening.

How does CoreChair compare in quality against my current office chair?
CoreChair has been introduced as a very high-quality product supported with a 12-year warranty. The patented internal mechanism is a high-precision component with a careful eye to final inspection processes to ensure optimal function over time. The product has been designed, engineered, and tested to exceed 1 million cycles using the BIFMA/ ANSI protocol.
All components of the chair are made from recycled or recyclable materials. The seat covers are made from 100% recycled post-consumer polyesters (water bottles).
How will CoreChair interact with my workstation?
CoreChair operates optimally when the user assumes a more open hip angle. This means sitting with the chair at a height that results in the knees being lower than the hips. The resulting position makes the user sit taller and engage in their workstation.
Properly adjusted the user’s arms should hang at their side rather than reaching out to their work surface. This new sitting height will likely result in the computer monitor being lower than ideal.
We recommend that you adjust your monitor height by using a portable desktop sit-stand station or a monitor attachment that allows for additional height adjustment.
Does CoreChair require assembly?
Yes, however, it is minimal and only takes between 10-15 minutes. The only tool that is required during assembly is a hex key. This tool is provided to you and is located in the seat pan of your CoreChair.
You can watch this video here for an idea of the assembly process

The CoreChair arrived in excellent packaging (secure, but not wasteful) and was easy to set up. A sound purchase.
I love that this chair lets me move around/ wiggle. The seat is very comfortable - best I ever sat on. The chair tips back a bit when I sit all the way back into it and I wish there was an adjustment available where I can tilt it forward slightly and keep it there. Otherwise, I am happy with my new chair.
I love this chair!
It is very ergonomic and helps me feel active throughout the work day
The chair was very easy to assemble. Great online videos about the chair. I did a final balance adjustment and it's perfect now.
The most comfortable chair I've ever sat in. Thanks for the great shopping experience too.
Love the overall feel
Love the overall feel, comfort level and ergonomics. I enjoy sitting on the chair, getting used to using it since it is different than a stationary chair
I absolutely love the CoreChair
I have been looking for a chair like this forever. I’ve had friends over to my office numerous times, and without fail, they are curious about my “weird-looking” office chair. When I invite them to sit in it for a while, they agree – it’s crazy comfortable! It arrived in a large, sturdy box. Every component seems to be very well engineered – built to last – and why wouldn’t it be with the very generous warranty that comes with it? In combination with my sit-stand desk, I have a work space that moves with me all day. I never could sit still – and now I don’t have to!
Dynamic while sitting! Love it!
This chair forces you to engage your muscles (which you should be doing) and actively moving while you are doing so.
So, the question I answer when anyone asks me for a chair recommendation is any chair that is going to cause you to actively sit and get you moving and that for me has always been the CoreChair.
