Design an ergonomic chair without using padding or cushioning

Chair concept sketches

Direction

After a wide range of exploration, I decided on a sling style chair supported by 4 sculptural arms that converge into a central base.

Key Ergonomic Goals

Consistent Back Support
  • The curvature of the seat should conform to the back with even contact
Solid Support
  • The solid portions of the chair should support getting up & down
Under Thigh Room
  • Suspended fabric seats typically pull taught under the thigh, causing strain. The seat should compensate for movement under load
Enclosing Seat
  • The seat should look and feel inviting to sit into, as if enveloping the user
Aesthetic Profile
  • Maintain an aesthetically pleasing and interesting form while hitting all ergonomic benchmarks

Ergonomics Testing

To validate and fine tune the ergonomics of the sling seat, I went through 4 rounds of increasing fidelity prototypes, testing with people of all body types.

Construction

I mapped each structural joint and seam out before starting production.

Planing walnut stock
Woodworking

The base is made of solid walnut hardwood joined with floating tenon joinery. It is hand carved to achieve the sculptural curves. The carving would be done via CNC in a production setting.

Fabric Seat

The seat is a faux sheepskin with a structural backing fabric. The pattern is cut and darts are sewn in to create the cupped seat shape, and the fur hides the seam lines. The seat is removable and secures via 4 custom steel brackets.

Results

Enclave is an elegant statement lounge chair with a sculpted wooden base and suspended faux fur seat. Its silhouette is striking, unique, and eye-catching, yet the form is timeless and fits within modern trends as well.

The wooden base is visually weighted and solid, grounding the form and giving structure, with sweeping curves that gently guide the eye around it, while the fur seat contrasts with the base, displaying how it would hold one’s body perfectly, inviting oneself to experience the comfort of its embrace.
