Core-flex Seating Technologies has designed a chair that offers you the benefits of motion all day long, with no distraction from your computer work.  By introducing natural, therapeutic motion into the act of sitting, the Core-flex chair keeps your blood flowing, your back strong and your body healthy. Designed in consultation with one of the busiest Spinal Health Centers in Canada, the Core-flex chair is unlike any office chair you have ever tried. Its patented Dual-flex seat allows natural, balanced movement for your legs, pelvis, and core, and the results are astounding. From the first moment you sit down, you will understand how much our bodies crave movement, and why other office chairs are so restrictive.

Posture's most important motion

The human body has one primary strategy for movement: walking.  This means that the supporting muscles and structures of the spine are highly adapted to the constant alternation of force from side to side, and research has identified this motion as the key to back health.  Sitting motionless fatigues your back muscles, leading to slumped sitting postures and a stressed lower back.  The Core-flex seat allows just enough movement to tilt the pelvis and stimulate muscles of the legs and core.  The results are greater comfort, an active core, better posture, and more calories burned, for every minute that you're sitting.

Dynamic Sitting and the Core-flex Office Chair

Core-flex Split Seat Features:

  • Encourages the natural alternating movement of the legs
  • Provides small motions that increase blood flow and stimulate metabolism
  • Reduces discomfort under legs and buttocks by constant alternation of pressure from side to side
  • Gently rocks the pelvis like walking, strengthening the spine and nourishing the discs
  • Allows full range of motion while reaching forward and sideways
  • Prevents swelling and cramping in the lower legs
  • Activates leg and core muscles more effectively than sitting on an exercise ball

Modern office chairs: the wrong kind of motion

The need for movement is well known within the seating industry, yet for 50 years the only type of postural change available in office chairs has been the backwards tilt or recline. Reclining is a way to rest more comfortably, but it is not an actual activity. Reclining is passive: it does not activate muscles and spinal structures, or stimulate the metabolism. In fact, time spent reclining in the sitting position is strongly associated with sedentary metabolic syndrome, a concentration of risk factors for diseases including type 2 diabetes, heart disease, colon and breast cancer, and obesity. This is where we get the (somewhat exaggerated) expression: “your office chair is killing you”. Clearly, the solution to sitting’s health challenges is not more reclining!

Only Core-flex chairs give your body the right kind of natural motion, all day long.

Faster Injury Recovery

"The consensus from my staff and patients has been, 'I can sit longer at work with no pain,' and 'my results have improved since I got the Core-flex chair.'"

"Work related duties such as sitting all day can and will erase the positive benefits the patients are working so hard to change. However, I've found that the patients who've acquired the Core-flex chairs, in conjunction with their rehab exercises, have seen faster results with their road to recovery."

"We empower our patients through education and training to strengthen their spines with home and in office exercises in order to make a positive change in their body."
