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.

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%!

    I’ve talked to two different people in the last two weeks about how much I love my Core Chair. It truly has made a difference in my lower back in particular. And it is super comfortable and fun. If and when I ever change jobs, I’ll have to negotiate taking my Core Chair with me!

    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.

    100% positive feedback from us!

    Initially I was a bit skeptical that this modest looking chair would take the place of my previous iconic office chair, but I quickly learned that my CoreChair delivered on all promises to provide long term sitting comfort and relief of my stubborn back pain.
    I now feel that my personal quest for health and fitness is well complimented with this innovative sitting solution.”

    Well done CoreChair. This is a quality solution.

    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.

    Good quality chair. However, I find that sometimes I feel like I am sliding down the seat cushion.

    • corechair

      Hey Tom,

      Thanks for taking the time to share your feedback with us. I’m sorry to hear that you are sliding in your new chair. Luckily, that is a quick and easy fix with just a few adjustments! I’d love to have one our of in-house Kinesiologists help you make those adjustments!

      Keep an eye out for an email coming your way. Chat Soon!

    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.

    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.

    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!

    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!

    I love that it is an adjustable chair! Depending on which shoes I am wearing (ie heels or flats), I can put my seat up or down. My last chair was not adjustable.

    I wanted to inform you that I presented the CoreChair to an orthopedic doctor and he was very impressed. He said that this chair is by far the best quality he has seen so far.

    I like it way better than my previous chair.
