Sore Back? Find relief with CoreChair.

Our tech innovation focuses on providing optimal postural support and movement. Unlike traditional office chairs with tall back “rests”, the CoreChair addresses back pain from the source– the pelvis. The innovative pelvic support cushion works in conjunction with the sculpted seat cushion to re-align your pelvis with your spine–creating the foundation for a balanced healthy posture.

Often when we experience back pain, our tendency is to rest up and stop the activity. However, moving on the CoreChar gradually works the back muscles in a controlled manner helping to avoid stiffness and alleviate pain. 

In fact, a study completed by Memorial University concluded that participants sitting in the CoreChair adopted a more upright posture, experienced less back pain and stiffness and had enhanced blood flow when compared to sitting in a traditional office chair.

Extraordinary comfort meets incredible pelvic support

The seat of the CoreChair is aggressively sculpted to embrace your sit bones and provide you with even weight distribution to relieve pressure points, prevent sliding, and deliver luxurious comfort.

The sculpted seat may dramatically help relieve sciatica and other nerve pain… so you can focus on your work, not your discomfort!

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 by MAYO Clinic.

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%!

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 work day
  • 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
Will CoreChair really help my back pain and/or posture?


The CoreChair was designed and developed by someone who truly understands the human body– Kinesiologist and Human-Movement Expert, Patrick Harrison. Unlike most office chairs that are designed to look a certain way, the CoreChair was designed with a research-based approach to address back pain, sitting discomfort, and sedentary behavior.

The innovative pelvic support cushion (in conjunction with the sculpted seat cushion), works to re-align your pelvis with your spine–creating the foundation for a healthy, balanced spine. Often when we experience back pain, our tendency is to rest up and stop the activity. However, moving on the CoreChar gradually works the back muscles in a controlled manner helping to avoid stiffness and alleviate pain. CoreChair combines optimal postural support and movement to create the perfect solution for sitting back pain.

In fact, a study completed by Memorial University concluded that participants sitting in the CoreChair adopted a more upright posture, experienced less back pain and stiffness and had enhanced blood flow when compared to sitting in a traditional office chair.

If for any reason the CoreChair doesn’t help your back pain, you can return it within 60 days for a full refund. We cover shipping costs both ways.

Does the CoreChair help sciatica pain?


Sciatica occurs when the sciatic nerve becomes pinched. This typically happens because the pressure is being applied to the nerve from a herniated disc, spinal narrowing, or even from the piriformis muscle that is located under the glutes. In any case, the Mayo Clinic (2019) suggests that in order to relieve pain and prevent it from occurring one must keep their postural muscles strong through regular exercise and maintain good posture while sitting. Both of which, the CoreChair promotes.

By re-aligning our pelvis into an upright and engaged position, and relieving pressure points under our pelvis while seated, the body is able to release pressure off the sciatic nerve. Then, through movement, we are able to improve the blood flow to the affected area and promote healing.

Will the CoreChair allow me to burn calories while I sit?


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.

How is the CoreChair different from other ergonomic chairs?

Traditional ergonomic office chairs still include a tall back as a reflection of corporate advancement. Contrary to popular belief, tall backs serve little purpose other than a carry-over of prestige or an opportunity to lounge in a diminished functional position– relaxed (case in point: the iconic Aeron Chair by Herman Miller was originally designed as a chair for the aging population!). This allows the body to settle into a reclined position which is most cases results in poor alignment of the user’s body relative to their work station.

Armrests are another hazard to our health. Their only function lies in allowing for an inappropriately supported person to lean to one side to stabilize their upper body. Armrests are also the most common inappropriately adjusted features on an office chair. When they are too high they tend to push the shoulders high causing discomfort in the upper back and neck. When they are not fitted properly they tend to contribute to nerve impingement in the forearm and neck.


So what does CoreChair do differently?

CoreChair addresses the “cause” of poor posture and back pain by creating a more aggressive posterior pelvic support. It 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 eliminates the need for armrests by providing the foundation for a properly balanced seated position. Without armrests, CoreChair users are able to move freely throughout their workstation without the interference of armrests hitting their desks.


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.

A Difference You Can Feel


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’ve talked to two different people in the last two weeks about how much I love my CoreChair. It truly has made a difference in my lower back in particular. And it is super comfortable and fun!

Nicole Judice Campbell, Ph.D., University of Oklahoma

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.

Ilmar Simanovsk

I used to get stiff shoulders and tension headaches on a regular basis. The occurrence of these headaches has been drastically reduced since I have been using this chair (about a year now). You can also do stretches right on the chair that helps with lower back pain as well.

7.5 Years of Development

The CoreChair was developed with a research-based approach and has undergone thorough engineering, field trials, and intensive testing.

Listen to the Experts…

The CoreChair fundamentally changes the nature of sitting from a passive activity to an active one. The effect that this has is principally on the muscles and joints of the body– particularly the low back. When the muscles are active they are coordinated and  strong… and they stay that way– they become healthier.


Chiropractor & Director of Recharge Wellness, GSH Medical Clinic

I use the CoreChair every single day and with my clients all the time! What I love about the CoreChair is that it is comfortable… like really comfortable.

Sarah Mariano

Fascial Stretch Therapist, @thestretchtherapist

One of the biggest issues of people sitting all day long is the postural muscles and core muscles are weakening over time. The great thing about the CoreChair is that it works on strengthening those weaker muscles. The better stability the person has, the better chance of long term recovery.

DR. DAVID LEE, BA, Bsc, DC, Masters Arts, FDM, NKT, SFMA provider


I recommend this chair to all my clients. A lot of my clients spend 12 hour a day sitting at their desks not moving… with the CoreChair they are able to keep everything moving throughout the day.
