Normal-Postures

Most chairs force us to sit at a 90-degree angle while our hip joint can only bend 60 degrees!

This causes our spine to become dangerously distorted, resulting in asymmetric stress in the cartilage, muscles, ligaments and joints.

That causes muscle pain and inflammation and can lead to discs disease as Heniation/Disruption/Degeneration, which means more pain, numbness in your legs and significant discomfort; walking, standing or sitting.

 

Normal Postures, such that makes a more than 90-degree angle between your torso and your thighs, can now be achieved effortlessly for long periods of time. This works for either upright or more tilted-back postures.

The Problem

sit 90

Conventional and Ergonomic chairs are designed for sitting either in a reclined position or with the upper body (torso) upright with a fixed 90-degree angle between the torso and the thighs.

However, the hip joint can only bend 60 degrees. The additional 30 degrees causes a rotation of the pelvis backwards, violating the natural curve (Lordosis) of the spine.

This strains the muscles of the back and causes asymmetric pressure on the inter-vertebrae discs.A 90-degree sitting posture over long periods of time may cause discomfort, muscle stresses, back pain, and later, disc protrusion, or disc rupture/herniation.

Lumbar supports or back cushions cannot solve your back problems.

 

Over 90 degrees Torso-Thighs 'Normal Postures'

In contrast, a sitting position where the angle between the torso and the thighs is closer to 135 degrees is relaxing, allowing the spine to keep its own normal curve (Natural Lordosis).

sit 135 Reclining backward is one good way to enlarge the torso-thigh angle and divert more weight into the backrest, preventing stress on the lower spine.


While reclining is great for resting, or for short tasks, it is bad for the upper spine and neck when working and need to counter-recline the head and neck forward at an angle. Such posture does not allow working comfortably at a desk or in front of a computer, where alertness and focus are essential.

Chairs should allow a person to sit in 'Normal Postures' where the angle between the torso and thighs is over 90 degrees. So that you'll be able to:

  • Effortlessly sit in each Normal Posture in a conventional way
  • Choose the amount of torso-thigh angle seamlessly
  • Switch seamlessly between postures

Solutions such as kneeling chairs, with a forward leaning seat and a knee-stopper to prevent sliding; or horse like saddles, are difficult to use for long periods of time. They require concerted muscle effort, a strong will and self-discipline to maintain the correct posture and may cause negative effects on your body as knee pains.children intuition

 

No one can question the simple and intuitive intelligence of a child that tilts a chair forward into a 'normal posture'. The question is whether we can apply this intuition to smart chair technology.

   FIT does it!
