Understanding a Sitrite Dynamic Chair

• The slope of the seat does two things:
  • straightens the back naturally.
  • distributes some body weight onto you shins.  You may notice some discomfort on your shins when starting to use a Sitrite chair.  We suggest that if this is a problem, you start by using the chair for part of the day for the first few days. 
• By increasing the slope of the seat, you are putting more weight onto your legs and less onto your seat/lower back.  This is ideal for someone with lower back pain or if using a computer for long periods of time.
• When sitting, the back can remain perfectly relaxed because, like a tower of blocks, gravity is holding you.  In a normal chair, muscles strain to hold you against gravity causing tired and strained muscles.
• Good posture is natural and effortless.  These chairs have won awards for good postural design and for the promotion of good posture.
• When muscles are relaxed, this helps prevent shoulder strain and OOS (occupational overuse syndrome).  The Sitrite chair may help eliminate OOS.
• Because your back is relaxed, you don't feel the need to lean back.  You only need a back on your chair to either:
  • Support your back when the design of the chair means that you need it, or
  • to lean back because tired muscles from leaning forward need a break.
    
• When needing to reach forward, the Sitrite chair encourages you to pivot at the hips.  In a conventional chair, usually the back will bend.
• When sitting, 80% of our oxygen intake is used by the brain.  Ordinary chairs make us bend forward thus compressing the front of the torso and so restricting oxygen intake by reduced lung capacity.  When our breathing is shallow, we quickly lose concentration.  The other obvious advantage of improved lung and heart capacity is the exhalation of toxins.
