What Makes CoreChair Different?

Highly Sculpted Seat

The seat of the CoreChair is aggressively sculpted to embrace your sit bones and provide pressure point relief, prevent sliding, and deliver comfort.



Our innovative technology is designed to encourage fluidic movement in all directions up to 14 degrees with an adjustable resistance feature that allows you to personalize your level of movement.

Made with High Quality Materials

The CoreChair exceeded all of the BIFMA safety and durability standards. This has allowed us to provide you with a 12 year warranty.


Pelvic Support

Our seat cushion works in conjunction with the low back support, to stabilize the pelvis, optimize your sitting posture, and reduce back pain and slumping at your desk.

Innovation that keeps you moving.

Sore Back? Find relief with CoreChair.


Our tech innovation focuses on providing movement with optimal sitting posture. Optimal posture paired with movement helps to strengthen core muscles, alleviate back pain, and avoid stiffness! A study done at University of Waterloo (2012) and Memorial University (2017) concluded CoreChair was effective in providing functional postural support.

✓ Chiropractor endorsed

Extraordinary comfort meets incredible pelvic support


The seat of the CoreChair is aggressively sculpted to embrace your sit bones and provide even weight distribution. The seat cushion works in conjunction with the pelvic stabilizer to relieve pressure points, prevent sliding, and provide added comfort...so you can focus on your work, not your discomfort!

~ Stretch and reach more comfortably.

Easy Personalization - choose your own range of motion

What good is a high end, ergonomic office chair if you can't figure out all the levers and settings? We love that the CoreChair is easy to use with simple, intuitive movements and the ability to select your range of motion. Adjust height, seat depth, and mobility and you're good to go! You'd never guess there are 48 moving parts inside the patented seating mechanism! Years of engineering, design, and research intelligence is efficiently housed within the chair structure - all precisely synchronized to encourage subtle movement and exercise opportunity.

Take control of your health!

Increased Metabolism - turn sitting into an activity that improves your health!

CoreChair is NEAT™ Certified. NEAT™ (Non Exercise Activity Thermogenesis, developed by Mayo Clinic) reminds us that continuous low intensity movement is extremely valuable for our health! Research studies by Mayo Clinic found that moderate movement on a CoreChair increased metabolic demand by 20%!

    Your chair is the only chair I’ve ever sat in that allows my hip with a torn labrum to stop hurting and thus not get inflamed from remaining in a seated position. Thanks.

    To my delight, I find that the design of the chair helps me to maintain far better posture than ever before when seated on my previous desk chair. I love that I can rotate my core while sitting and can stretch back safely and comfortably.

    I’m a nursing student and I spend a lot of time sitting, studying, reading and writing papers. The CoreChair is the most amazing office chair I’ve ever used. It’s comfortable and really does help my back during those long study sessions. I would recommend it to anyone who sits for long hours, as you really do have to be considerate of your body!

    Kevin Vecmanis, Vancouver

    I founded a fintech start-up in downtown Vancouver and I spend a lot of hours sitting – whether I’m coding, researching markets, reading, or interacting with customers. I used to sit in a rock-solid, rosewood chair that I took from my kitchen table but it was really starting to negatively impact my productivity.

    I like to stay in shape – I run every morning and workout as much as I can. I’m also aware that sitting too much in the wrong position can really “undo” a lot of the benefits you get from daily exercise.

    I was introduced to the core-chair from a super-knowledgeable sales rep – a former iron man competitor and all-around athlete. He’s someone who really understands biomechanics and preaches best-in-class health practices. When he told me I’m negatively impacting my health by spending all day slouched over coding, I listened!

    I spend about 12 hours a day coding these days, and I’ve probably spent over 1000 hours in my core-chair. The stiffness and soreness I used to get from sitting all day is gone. My favourite thing about the chair is that it has really made me cognizant of my posture and sitting position – it has a weird way of self-correcting your posture.

    If you spend any amount of time sitting, I can attest to how amazing of a product the core chair it. Talk to Tristan and get him to change your life!

    Sarah Roberts, ON, Canada

    I LOVE my CoreChair! Being able to actively sit while working is incredible. I no longer feel the stiffness in my back and neck that I used to, and it is wonderful to keep engaging my core while seated. The technology built into this chair is undeniable and it is so strong and supportive while also taking up FAR less space than other chairs I have owned. I would highly recommend this chair to anyone who works at a desk and I can’t wait to see how far this company grows in the years to come as we all begin to realize that “sitting is the new smoking”! Well done, CoreChair, on doing your part to create a healthier workforce.

    I have just had back surgery and have come to understand how problematic sitting at a desk all day has become and how it has contributed to my back problems. Your new chair dramatically changed my sitting posture and I am exploring different ways of using it to build core strength. I have been telling everyone that sitting is the new smoking in terms of health hazards. I think your new chair is coming on the market at the perfect time and I wish you all the best with it.

    I LOVE my CoreChair! I have always hated sitting still for long periods of time, but I can keep working and rocking all day long in my CoreChair. As someone who perpetually squirms and fidgets in other chairs, CoreChair facilitates healthy movement throughout my day.

    We have been very happy with the CoreChairs. It has been beneficial for ergonomics and my colleague who has 20 years’ experience from the engineering field, said that his back pains disappeared when he started to use this chair. He had those for years before coming to work in Matricomp. We now have CoreChair for everyone here (3 people).
    Also I am happy with your delivery and service.

    Dr. Kara Fitzgerald, ND Naturopathic Doctor

    My “Achilles heel” in life is low back pain. I wore a brace as a child for scoliosis. Today, if I don’t stretch and keep my core strong, I experience back pain. Not surprisingly, my back is extremely finicky when it comes to my office chair. I’ve spent endless years adjusting my office chairs with pillows and pads – all to no avail. Enter CoreChair and active sitting. I purchased my own chair about six months ago, frankly expecting my back to reject it. But lo and behold, I love it! I’m sitting on it as I type this. The CoreChair actively engages my core muscles in a gentle way. And it’s endlessly adjustable. Typing tendonitis? Gone with my CoreChair. I give this chair my highest recommendation. And they’ve got a great refund policy too so you can give it a thorough try before you commit, just like I did.

    I am an 81 year old Mother and Grandmother who has spent 35 years in the past sitting in an office at a desk with poor Office Chairs, I now have arthritis and back and neck problems because of the “Sitting Disease” as they call it today. My Hobby is knitting and I spend many hours sitting but now that I have a CoreChair it has changed the way I feel, if my back is aching and I sit in the CoreChair it relieves the pain. A lot of older people like myself have trouble getting up after sitting for a while with the CoreChair there is no problem it moves with the body, also with Seniors exercising is a struggle but with the CoreChair you can exercise while sitting which helps build muscle strength which we lose as we get older. The CoreChair is not just for the younger generation but more importantly it is for us Seniors as well.

    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! Thank you CoreChair!!

    Dear the CoreChair team,

    As someone who has had the chronic lower back pain and receiving chiropractic treatment for over 2 years, I am thrilled to say that after only 2-3 weeks of using the CoreChair my back pain is minimal and I am able to spread out my treatments. I can confidentially say the activity aspect of the chair keeps my back feeling loose so I do not need to make as many laps around the office to get that much needed stretch from sitting all day.

    Thank you for your impeccable customer service and invention of the CoreChair!

    Warmest Regards from a very happy customer.

    I am a radiologist and spend most of my day sitting and reporting cases. I have tried several ergonomic style chair and stools over the years. The CoreChair is the absolute best in my experience. I can sit through my work and at the end of a busy day I have no stress in my back or legs. The CoreChair is a must for anyone spending long hours at a workstation. Try it and you will agree.

    As a massage therapist, I know the dysfunction that can happen if your pelvis does not move correctly and you don’t use those muscles around it. I recommend using this anyone who sits a lot because it will help mitigate a lot of those aches and pains that you get from sitting.

  23. Rated 4 out of 5


    I asked myself, what kind of office chair has no armrests…sitting in the CoreChair, I felt comfort…the support, immediate warmth and release on my lower back felt very good…not only that…I can feel my abs working…the kind of chair that provides for a healthy lifestyle, freeing those who feel chained to their chair. Thanks CoreChair.

  24. Barbara, Weinheim, Germany

    I am very happy with the CoreChair! I am using it in my office since this is where I am sitting pretty long hours, and my back is much better since the chair is there. I am actually missing it during the weekends at home. Just yesterday I had an appointment with my chiropractor. He was very satisfied about the progress I made and was impressed that my muscles are much better in balance than they used to be. The CoreChair has really improved my daily life!

    York Regional Police: 911 Center

    I’m never, ever, ever parting from my CoreChair and here are the reasons why:

    I find it helps with my posture because it has no arms to promote bad posture
    The back of the chair is positioned in the perfect spot to adequately support my back
    In short, I refuse to part from my CoreChair.

    I can tell you with the two chairs in our office, there is a fight every morning either of them are away amongst the remainder of the team to steal one for the day. I personally do not wear my entire use of force for the day as I have an ongoing back issue that I suffered a few years ago. This chair and standing desk combination has done wonders for me. At first, it was a little hard to adjust to but once you correct your posture the chair is great. If you are feeling good and solid for the day you can loosen off the tension and move your core a ton throughout the day.”

    Prior to getting my Core chair, I used a $1000 “executive” chair that I assumed was the state-of-the-art seating experience for those of us who sit behind desks. The CoreChair was a Christmas gift that I immediately adopted. I am now always comfortable sitting at my desk and no longer feel the need to continuously adjust my position. Well done CoreChair guys!

    The CoreChair was recommended by my physical therapist as a secondary option to an ergo ball since standing wasn’t promoting healing from my car accident injuries.
    I am excited to finally be on the road to real healing. I’ve been at a standing desk (by choice) for two years since traditional chairs are painful but the CoreChair isn’t painful! I can actually sit in it all day long (with breaks) without blinding and debilitating pain

    I have been suffering from lower back pain for over 30 years, brought on usually after long periods of sitting and working at my desk and computer. The usual symptoms I suffer after such a sitting session are the inability to stand straight and walk without lower back pain. After using your chair for only one day I noticed a vast improvement in increased mobility and reduction of pain and muscle spasm. After several weeks of regular chair use, I am now virtually pain free and no longer dread sitting at my desk. Thank you for designing and manufacturing such a high quality and useful product. I must also commend you on your excellent customer service and positive attitude of your support staff. All in all, another great Canadian innovation – I wish you continued success and the opportunity to bring lower back pain relief to many more sufferers.

    I have lower back issues from years of neglect and poor posture. My job requires that I sit for long periods, which can cause chronic lower back pain and difficulty with movement. I was excited to try the CoreChair and after 6 month of use, I am finding that I have eliminated the lower back issues. I can sit with comfort and find that the action of the chair keeps me engaged with my body position and movements. When I have to sit in a regular chair for any period of time, I now find that I try to alter my position to mimic the CoreChair alignment since it feels better on my posture. Best investment for someone who spends lots of time sitting.

    I love this chair! From the moment I sat down on it at the trade show where I was first introduced to it, to the moment I watched the Dragon’s Den episode, to the next and the next.

    The proof for me was in the pudding, as it is often said. As a graphic designer I have a sedentary job, with a day job and freelance clients at night, I spend more time than the usual person sitting so this definitely captured my interest.

    While I sat there talking to your sales and manager who happened to have a 6th degree connection through a friend in my field of business, I used the CoreChair, rocking back and forth and all around. After 15 minutes sitting in the chair I got up and my sore back was refreshed, it felt loosened and the compressed sensations I often get in my lower back were gone. That day had been especially tiring, walking the trade show floor for work, I was now feeling so much better. I have recommended this chair to anyone who will listen.

    Thank you.

I found myself spending less time in the gym, I had become sedentary. The CoreChair has been great for my core strength, back pain and stiffness is gone.
