Membrane :Ergonomic Sacral Support

Brief : Provide a work chair that supports the entire spine and addresses the differences in the spinal anatomy within that support. The dynamic material construction of the Membrane chair allows it to adjust naturally the leaning and turning motions of the sitter.
Most work chairs, however, are too rigid to allow the sitter’s torso to move the way it prefers. To compensate, sitters tend to move away from the backrest, thereby losing the support for the back.
Nor do most work chairs equitably support the entire spine, from the thoracic region to the sacrum, and the unique requirements of each of those spinal areas. While they may provide support to the lower back, the upper back is often overlooked.

Design Solution: Minimize chair structure and eliminate the need for foam padding by tensioning a material that provides dynamic support. Engineer the chair so the structure fits differently proportioned persons.
A topographically neutral seat and backrest, when designed to support a wide range of weights and proportions, ensures that people would get the benefits of the chair’s pressure distribution because of the TechnoGel BackSupport. Positioned comfortably on an adaptive suspension material, the sitter’s body, rather than the chair’s structure, dictates pressure distribution.

Sitting in a reclined position in a chair with
topographically neutral support distributes
pressure across the thoracic area and away
from the spine.

Sitting in a sling-type chair puts pressure on
the gluteus maximus muscles at the sides
of the buttocks as well as on the heads of the
femur bones and sciatic nerves.
Because of the ribbed back the backrest arches under pressure and user movement .It follows the natural “ S” curve while under pressure and provides continuos support while providing a certain amount of Torsional Flex.
