Core Strength

Movement is the key to maintaining core strength and our shorter back rest builds core strength.



Movement burns calories and helps manage our weight and mood, which bolsters our energy! Tango users can expect an increased metabolic demand of 20%!


Highly Sculpted Seat

The seat of the Tango 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. 

“A great benefit of this chair is that your core actually gets stronger over time versus in other chairs where your core may decline over time.”

Innovative Pelvic Support

Unlike traditional office chairs with tall back “rests”, the CoreChair addresses back pain from the root cause– the pelvis. Tall backrests serve little purpose other than to allow your back muscles to turn off and rest all-day. Instead, we removed the backrest and designed an office chair with a highly sculpted seat cushion that works in conjunction with the pelvic support cushion to hug the top of your pelvis to automatically sit you up in an upright posture. This prevents slumping, optimizes sitting posture, and reduces stubborn sitting back pain.

Fluidic Movement

Movement helps avoid and alleviate back pain and stiffness. Our innovative patented technology allows you to move in all directions up to 14 degrees with a pivot point immediately underneath the seat pan to allow you to stay balanced and have complete control over the chair’s movement. The CoreChair also features an adjustable resistance lever giving you the ability to lock the chair into place to restrict movement when needed.

Highly Sculpted Seat Cushion

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. Customer reports has shown that the sculpted seat cushion may dramatically help relieve sciatica, tailbone, and hip pain.

Will the Tango really strengthen my core muscles?

When we collapse into a traditional chair, which may indeed feel comfortable, our core stabilizing muscles are too relaxed and tend to approach atrophy or muscle wasting. Continuous low-level stimulation of these critical stabilizing soft tissues will definitely add to your core strength and you can expect a carryover effect on your other daily activities.

While the Tango is not as unstable as an exercise ball, it does engage your core stabilizing muscles very much on par according to a study conducted by the Dept of Kinesiology at the University of Waterloo.

What is it like to sit in a Tango?
  • More alert and productive throughout their workday
  • 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
How is the Tango different from other ergonomic chairs?

Tango 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.

Tango eliminates the need for armrests by providing the foundation for a properly balanced seated position. Without armrests, Tango users are able to move freely throughout their workstation without the interference of armrests hitting their desks.

Tango 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.

Can I try it before I buy it?

Selecting the right office chair is not something that can be accomplished in a brief trial. CoreChair is happy to offer a 30-day satisfaction guarantee to allow sufficient time to experience the benefits of this unique sitting solution.

If the Tango does not provide the sitting experience we know we can, contact us and we will assist with any suggestions to optimize fit and function or we will arrange to have the chair picked up and returned.
