CoreChair Information

For warranty purposes, the CoreChair has a weight limit of 250lbs.

The CoreChair has been rigorously tested through 1 million cycles and did not present any change in the function.  Therefore, it can withstand weights in excess of 250lbs, but is limited by the 250lb maximum hydraulic lift.

We suggest the Classic model for persons with a heavier stature as it is a more robust chair than the Tango and has adjustable resistance.  The advantage of the adjustable resistance is that you have the ability to control the amount of movement you get from the chair.

While we don’t have any specific stores in order to trial the chair, we do offer a satisfaction guarantee so you can try it in your own space.

Selecting the right active sitting chair is not something that can be accomplished in a brief trial. CoreChair is happy to offer a 60-day satisfaction guarantee (on the Classic and Sport models) and a 30-day satisfaction guarantee (on the Tango and CorePerch models) to allow sufficient time to experience the benefits of this unique sitting solution. *Please see Return Policy for details.

Be sure to keep the original packaging just in case you might want to return.

The external dimensions of CoreChair are similar to any traditional office chair and will nicely compliment most workstations.

The CoreChair is designed to fit persons who range in size from approximately 5 feet to over 6 feet tall. Please watch the assembly instructions to determine the best fit for you.

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:

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.

The sculpted seat and the low back work together to position your pelvis in an upright vertical orientation which encourages your spine to find a natural balance that does not require added supports.

When sitting balanced with an optimal posture, there is no need for armrests and your upper arms should hang loose by your sides as they do when you stand.

It is important to assume a seated position that allows your elbows to be at 90 degrees or a bit more open, with your hands resting on the work surface.

The use of arm rests are often counterproductive as they often encourage leaning which disturbs optimal posture as well as unnecessary pressure on your forearms.

Yes. CoreChair is designed to provide an ideal combination of optimal postural positioning with safe movement. It is a perfect orthopedic intervention when properly adjusted because CoreChair embraces your pelvis and allows movement of your hips/ thighs as well as your spine. It is an excellent compliment to other health care interventions and especially for prevention.

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), hydrate intervertebral discs and stimulate blood flow. CoreChair has proven to be a very effective contribution to persons with chronic back pain.

Traditional ergonomic office chairs most often provide too much support that restricts movement. A traditional ergonomic chair is most often recommended to position the user in a slightly reclined position (105-115 degrees) which causes the user to have to reach out to their work surface and engage the supportive musculature of their upper back and shoulders. Due to fatigue from assuming a position such as this, the use of arm rests are encouraged to allow these muscles to recover.

An additional shortcoming of this position is that the users pelvis begins to creep forward and tilt backward, causing their lumbar spine to flatten. This is often when a lumbar support is recommended but it only addresses the symptom and not the cause.

Many people who sit in traditional chairs have a tendency to perch on the front edge of their seat without any back support. Eventually this causes fatigue and collapse of their posture.

CoreChair provides an engaged sitting position that promotes optimal posture as 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.

When your CoreChair is fitted properly and you are sitting balanced, you will experience a freedom of movement that allows natural movements of your entire spine through flexion, extension and rotation.

The CoreChair has a pivot point immediately beneath your center of balance that allows movement up to 14 degrees in all direction. Much of the movement that you will experience is referred to as “incidental” movement that has earned CoreChair the NEAT certification. NEAT certification is granted by the Mayo Clinic in recognition for the inclusion of the healthy movement opportunity that you can experience throughout your day. During this study, CoreChair was determined to increase caloric burn 20% higher than traditional chairs.

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 sitting position, much like they might after their first few visits to the gym on a new exercise program. This may result in some initial discomfort as you begin to recruit core stabilizing muscles but much like regular trips to the gym, you will experience adaptation and conditioning and this discomfort will diminish.

In order to lessen this potential transitional discomfort, we suggest setting the resistance to the highest setting, and releasing it for short durations throughout the day until your body becomes used to the change.

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 as a result of the enhanced position and support.

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 through the day, from sitting to standing and walking opportunities.

We also encourage preventative and therapeutic complimentary solutions such as yoga, safe training, and massage as well as physiotherapy and chiropractic care.

CoreChair has been designed, engineered, and tested to be a very high-quality product supported with an 8-year warranty. The patented internal mechanism is a high precision component that is intended to undergo a long life of constant movement.

The product has been tested to exceed 1 million cycles using the BIFMA/ ANSI protocol, where the accepted industry norm only requires 300,000 cycles.

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 than they might on a traditional chair and more engaged or closer in their worksurface.

Properly adjusted the user’s arms should hang at their side rather than reaching out to their work surface. Ideally your elbows should be 90 degrees or slightly more with your hands on the worksurface. This new sitting height will likely result in the computer monitor being lower than ideal and you may need to adjust accordingly.

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.

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 they don’t have proper pelvic support and in order to maintain an ideal sitting posture, they have to engage their core stabilizing muscles at a high level, continuously.  This is exhausting and eventually fatigue sets in.

On the CoreChair, the pelvis is embraced with a sculpted seat and a low back support and your pelvis is held in a neutral posture. This alleviates the need to over engage your core. This pivot point on a CoreChair is directly beneath your centre of balance. So, with your pelvis and your thighs supported, and your feet firmly on the ground, you have a very stable three-point base of support.

Another misconception is that we might get tired from moving. In fact, when you don’t move and don’t get optimized blood flow and 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.

While the CoreChair is not as unstable as an exercise ball, it does engage your core stabilizing muscles on par according to a study conducted by the Department of Kinesiology at the University of Waterloo. The added benefit is that when you have the postural support of the CoreChair, you can enjoy sitting and moving in comfort for many hours every day.

The shortcoming of the exercise ball is that you will tend to fatigue too quickly and when this happens your posture has a tendency to collapse and then you will experience the discomfort associated with this position.

When we collapse into a traditional chair, which may indeed initially feel comfortable, our core stabilizing muscles are disengaged and over time become weak. Continuous low level stimulation of these critical stabilizing soft tissues on a CoreChair will definitely add to your core strength and you can expect a carryover effect to your other daily activities.

“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 challenged 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.

CoreChair is NEAT certified.

It doesn’t matter whether we sit or stand, we need to move.

Presenteeism is the new term that emphasizes the benefits of good ergonomics and wellness in the workplace. Absenteeism due to illness or injury is obvious but think of the days when people show up for work distracted by pain and become less productive.

The CoreChair team would be happy to engage in a discussion on how CoreChair can be part of any workplace wellness program. We can even share documentation highlighting research validation that speaks to:

  • Reduction of back pain
  • Stimulation of metabolism to combat “sitting disease”
  • Increased productivity

CoreChair is designed to provide an optimally supported sitting posture by embracing the pelvis and move in all directions up to a safe 14 degrees. Movement resistance is adjusted very simply and has five settings. The highest resistance results in very little movement with more emphasis on postural positioning.

If you are new to CoreChair, we recommend you begin with the high resistance and ensure that you have achieved the optimal adjustment to optimize your posture. Intermittent shifting through the day from high to low resistance will begin to demonstrate the feel of the movement.

Most users quickly adjust to the dynamic movement at the low resistance and use this as their default. The midrange adjustments for resistance are very helpful when you are sitting taller with a more open hip angle (knees below the hips) and avoids the sensation of sliding while maintaining movement in all directions.

If you feel like you are sliding forward in your CoreChair, you may have to make a quick and easy adjustment to your center of balance.
