Aero® High-G® Seat |

"Sit
up straight!" It turns out your parents were right.
Sitting straight helps create a smooth lumbar curve, essential
for seating comfort. But it’s impossible to sit correctly
in conventional seating, which is why sitting is painful.
Oregon Aero seat cushion systems, on the other hand, provide
pain-free sitting. Here is the story in pictures:
|
Why
Are Conventional Seats Painful?
|
| 1 |
 |
• Our
body weight lands on the pelvis’ ischial tuberosity
(the "sits bones") but the center of gravity
of the upper body is behind the sits bones — SO... |
| 2 |
 |
• The
pelvis is rotated back, down and around the sits bones.
This flattens the lumbar spine and compresses the anterior
(front) of the disks at the lumbar spine, causing pain. |

 |
| • |
Anterior
surfaces of wedge-shaped lumbar disk compressed to
parallel position by pelvic rotation back and down |
| • |
Undesirable,
painful position |
| • |
Produces
low back strain, pain |

Using
cushion to push on the lumbar doesn’t overcome
gravity! |

Pelvis
tipped back and down |
| • |
Anterior
surfaces of wedge-shaped lumbar disk compressed to
parallel position |
| • |
Undesirable
relative surfaces of adjacent vertebrae |
| • |
Painful
position |
| • |
Produces
low back strain, pain |
|
| 5 |
 |
• Our
instinctive response is to try and place pressure under
the pelvis by slouching or using some kind of lumbar support,
but this results in a complete curvature of the spine,
compressing all of the disks up to the neck. Look closely
at the spine photo and at Mike slouched in his office chair.
Look (and feel) familiar?

• Note
the top of the spine is rotated forward. This is felt as
a tendency
for the head
and chest to fall forward and compress the diaphragm area
of the upper abdomen. So — with great effort — we
try to sit straight and pull our shoulders back. All of this
is our clue that the pelvis is rotated back and down and
that our back will hurt eventually, no matter what we do
with lumbar cushions! |
Why Oregon
Aero® Seats Are Painless |
Painless Seating = Proper Lumbar Curve
and Pelvic Position
It's not the lumbar support that matters so much,
it's shifting
the hips and pelvis into the proper position:
