Solution

9. Product Positioning Statement
For tired men and women who need a great place to sit down, ChairUtopia is a
cardboard chair that has great support, armrests for comfort, and even folds away
for storage. Unlike standard metal, wood, and plastic chairs, our product preserves
the environment by using 100% recycled cardboard
Key Design Features: Foldable to conserve space, Armrests, Cheap and Affordable
Goals in the Design: We aim to keep the cost of our chair as low as possible while
maximizing safety and durability. Our optimal design is a stylish ergonomically
sound chair foldable for storage in just a few easy steps.
Estimated selling price for the Master Chair: $15.00 Our team derived this price for
our chair by adding up the labor costs associated with making the parts for our
chair. Our cardboard is 100% recycled and is free so no part of the costs goes to
cover costs of material.
