Flatpack Chair
Industrial Design, Year 2017
For this project, I worked in a team of 4 to design and build a sleek and modern chair inspired by IKEA products, which could be flat-packed to save storage space in warehouses. The purpose of this project was to come up with an innovative design which could fit within bounds of a 6' wide, 6' long, 0.75" thick piece of square plank as our project constraints. My team wanted a multipurpose chair, so we created a storage section underneath the seating and considered angles and curves for the backrest to maximize user ergonomics. I created the CAD model for the chair in Autodesk Inventor. The design of the chair also accounts for environment and material sustainability, as it largely removes the need for nails, screws, and other attachment tools, which would save overall material and production cost. The finished prototype was constructed with hand tools, like the jigsaw and bandsaw, then sanded down to remove the edges. The mass-market product is expected to be laser cut.

The finished prototype constructed with hand tools then fitted together.


The CAD prototype built and dimensioned in Autodesk Inventor 2017.

Testing comfort of seating on people of different heights. The chair was rated to be very sturdy and comfortable.
