The CoreChair Development Journey Part 2: Design Implementation

The creation of a mechanical solution to provide a smooth riding mechanism that would allow a person to introduce movement into their daily lives at the desk was riddled with engineering challenges. The next step was to create a functional human interface that would provide significant measurable outcomes and a process to validate the efficacy of this design.

In my previous world, I was blessed with a successful company designing and manufacturing seating solutions for persons dependent on wheelchairs for their mobility. Originally a practice of custom seating for persons presenting severe fixed orthopedic deformities where the primary objectives were orientation of the head in space and optimization of their activities of daily living. This practice evolved into standardized seating solutions that focused on comfort, positioning and prevention of ischemic tissue trauma. 

The development of these rather sophisticated designs required a significant amount of research on anthropometric standards and material dynamics as well as studies including pressure mapping, spine function and orientation in space to optimize the users experience.

It was the outcome of this process that contributed perfectly to the CoreChair human interface. 

The aggressively sculpted seat is a carry-over that is effective in promoting an upright pelvis and uniform pressure distribution to enhance comfort. The low back support works with the seat to embrace the pelvis and further enhance this neutral position to promote greater natural extension of the spine while in the seated position.

Now it was time to see how well it worked in a real-life situation. 

With the patience of a plethora of allied health care professionals and friends, family and acquaintances, we tested the system in clinics and offices to learn how it affected comfort and positioning on a variety of body types and sizes. We then sought out Dr. Jack Callaghan, PhD, Canadian Research Chair at the University of Waterloo, Department of Kinesiology and a renowned researcher in the realm of ergonomics. Initially we embarked on a couple of pilot studies to gain some credible scientific feedback on the design and how we could improve it. Then, after implementing this knowledge in tandem with practical field trial feedback we returned to Dr. Callaghan to perform a full kinematic study on how the CoreChair performed relative to traditional office chairs and the exercise ball. 


The outcome of this study provided validation that the design performed as intended and allowed us to continue tweaking design features to make it even better.

An evolving design began to take form and the engineering took it to the next level. At this phase, we had to decide if we were going to introduce a low-priced commodity solution or press on to create a robust product that would encourage people to move and enjoy a long life expectancy of their chair. Opting for a high-quality solution CoreChair is essentially over engineered to achieve this. Following BIFMA/ ANSI quality standards the chair was designed, engineered and tested to exceed expectations of traditional chairs with the key measure being a dynamic durability test that exceeded 1 million cycles.



Sensitive to the environment, durability is a key design feature to ensure that we don't find it contributing to a land fill site. We also designed it to use either recycled or recyclable materials and the efficient packaging ensured that we were able to leave a smaller carbon footprint with user friendly assembly. 

Next was the stage of tool design and manufacturing to ensure high standards of quality control and repeatable production on larger scales.

Stay tuned for Part 3 of the Journey.

Setting Desk to Right Height
Setting Your Desk to the Correct Height

April 09, 2018

When buying an ergonomic chair, we often size the chair based on our height. However, that doesn't always mean it is correct unless you also sized your desk the same way! You could be in a chair that is perfect fit for you, but if your desk isn't also at the right height, you are going to feel the pain!

Introduction to the CoreChair

Patrick's Story

With a degree in Kinesiology, the study of human body movement, Patrick has committed his personal life to an active and healthy lifestyle and pursued solutions to optimize this among others. 

                                                            Patrick Harrison on a Conference Call   Patrick Harrison Snowboarding 
Patrick's initial success was the development of a company that focused on the design, manufacture and distribution of specialized seating solutions for non ambulatory persons dependent on wheelchairs for mobility. Special Health Systems Ltd., was considered a leader in this field in North America as well as other global centers prior to the sale of this company in 1995 to US based Invacare Corporation. 
After the sale of this company, Patrick pursued many other entrepreneurial ventures that ranged from agricultural to philanthropic opportunities, but was drawn back to his passion to create solutions that would address physical challenges experienced by everyday people.

With the emerging awareness on the perils of sedentary lifestyle coupled with the musculoskeletal damage incurred by desk jockeys, Harrison was inspired by the number of persons who intuitively sought activity in their day at the office by taking an exercise ball to replace their traditional office chair.
Thus he began what became a 7 plus year project to create what is best described as a disruptive innovation by developing an active sitting chair that is now commercially known as CoreChair.

Aware that human nature and the resistance to change is the biggest challenge that we all face, Patrick collaborated with Centers of Excellence such as the University of Waterloo, Mayo Clinic, Cornell University and others, to validate the efficacy of this design. 
In parallel, Patrick sought practical input from clinicians, health experts and everyday people to gain feedback on the design evolution to ensure a comfortable and effective solution. 
The result is a very high quality seating solution that challenges traditional doctrine of healthy workplace environments, with attention to detail on every day needs and value to those who use it. 

Our Core Design

The vision of CoreChair is to offer the world’s healthiest, ergonomic and therapeutic office chair. Paying little mind to convention or tradition, we chose to focus on you, the sitter. Our tech innovation focuses on optimal posture through core stabilization and movement that mobilizes key joints most affected by sitting. We made our seat highly sculpted to relieve pressure points, prevent sliding and deliver comfort. It works in conjunction with the low back, stabilizing the pelvis to optimize your sitting posture, reduce back pain and prevent slumping at your desk. Many of us are actively seeking therapeutic remedies to help reduce our back pain. Prolonged static sitting in traditional chairs (even high end ergonomic chairs) can result in uncomfortable back strain and lack of movement. Invest in your health with an innovative seating solution designed to harmonize your personal movement with your chair.
