Study based on “convenience in usage for human” and it is a study of shape in equipment or machines without having any stress or tiredness concerning for both mentally and physically.
Comfort in sitting position can be calculated.
Careful analysis was made of all measurements and angles, such as the length and angles of the seat surface and backrest in an attempt to discover the ideal fundamental sizes that help prevent the fatigue of being seated for long periods as well as aid the customer fs posture.
02: Shape of back rest.
Stability is in direct proportion to relaxation.
The key to give customer comfort in sitting position is to let upper waist relaxed by holding waist and back properly. We designed the line from the armrest to the backrest fits the customer's body line so that the backrest will firmly and comfortably supports customer's waist and back.
03: Seat Structure
The "contradiction" of the seating surface is compatible.
By softening the back area of the seat whilst keeping the front area slightly firmer, we have come considerably closer to achieving an ideal distribution of body weight throughout the chair. The secret to this is in the varying densities of the foam seat cushion. The density of the foam under the buttocks, where pressure from the body is highly concentrated, is of a low, so that the body sinks snuggly down, whilst the surrounding foam is slightly denser to firmly hold the body in place. In addition to this, the seat covering is extremely pliable enabling in to easily mould to the individual shape.
