2. Inspiration for the Luxury Chair Design

3. Initial Idea
• Luxury chair with looks of an
Octopus
• Legs in the shape of tentacles
• Round Soft Back Support That
gives comfort as well as looks like
an octopus head

4. CURRENT PROTOTYPE
• MORE LIGHTWEIGHT
• ADDED SOFT CUSHION FOR HEAD COMFORT
• ADJUSTABLE ARM-REST WITHOUT THE
DISCOMFORT AT BOTTOM UNLIKE INITIAL
PROTOTYPE.
• LEGS & HANDLE ARE DESIGNED MORE LIKE THAT
OF AN OCTOPUS
ANTHROPOMETRIC DIMENSIONS ARE ON THE NEXT SLIDE

6. Details of the design
• The Seat back-length And Seat width are taken 95th percentile to
accommodate larger people
• While 5th percentile Knee Height is used for chair height to let
everyone’s legs touch the ground.
• The Head Cushion is used big so as to accommodate both 5th
percentile and 95th percentile group.
• The 112.5° angle is for relaxing posture.
