DESIGN NAME: Cirro
PRIMARY FUNCTION: Lounge Chair
INSPIRATION: Cirro was a response to the classic designer’s challenge to create a chair. This rite of passage was rooted in an interest in the use of laminated plywood for furniture, which started with the Eames Lounge Wood Chair roughly 70 years ago. I really wanted to explore new ways of using this same process, especially harnessing new technologies to enhance methods of creating unexpected forms. Plywood is excellent at creating strong two-dimensional forms, but I really wanted to make fully three-dimensional forms from the materials to create a more dynamic piece.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: The Cirro lounge chair features a cantilevered seat and is made from custom-laminated cherry veneers. The design was motivated by the Eames Lounge Chair’s innovative use of plywood. Cirro bends the material’s formal limitations to create ambitious volumes, all while using contours that harness the materials great lateral strength. The cantilevered seat yields under the sitter’s weight, creating a sense of floating gently above the ground. The gentle, relaxing feeling of sitting in Cirro inspired its name, which is derived from a prefix for a family of wispy, high-altitude clouds.
OPERATION / FLOW / INTERACTION: Cirro was designed to present an enticing perch, extending towards the user with a gesture of invitation. The form reaches out, yet in the moment of sitting, Cirro yields gently under the weight of the user. This transitional moment moves the user into a relaxed sitting position. By tuning the bend of the cantilever, the elegance of the clean, thin contours of the material make it a strong visual statement without losing an intimate, comfortable, plush feeling. Since Cirro moves slightly as the user adjusts her weight, it can accommodate many different sitters and sitting positions.
PROJECT DURATION AND LOCATION: Cirro was designed in the April, 2013, and completed in June, 2013 in Stanford, California/USA. It was on exhibit at the Thomas Welton Art Gallery in April 2014.

PRODUCTION / REALIZATION TECHNOLOGY: Cirro overhauled the plywood lamination process, hybridizing old male-female buck lamination methods with composite fabrication vacuum-molding techniques. The vacuum molding process allowed for separation of the compression of the material during curing and the geometry being forced on the material. This allowed for huge leaps in creative use of the veneer’s material characteristics, including more fluid contours and volumes. Further, the jig required for fabrication isolates the critical ergonomic geometry, facilitating full-scale design iterations to refine the form.

RESEARCH ABSTRACT: Cirro research began with design, looking at Shaker and Arts and Crafts furniture to the first mass-produced chairs. The Eames innovation in production of plywood chairs with the LCW was the entry point. Plywood manufacturing processes were researched: two-buck bending, single buck lamination, steam bending, and composites forming methods. Plywood chair research found many single plane bending designs that have no additional characteristics than can be seen from the side. The manufacturing process was redesigned to enable bending around axes perpendicular to different planes.
CHALLENGE: The creative challenge inherent in this process was the cohesive integration of many divergent factors: ergonomics, overall dimensions, visual appeal, creating volumes, structural strength, material thickness, response to sitting, total material costs, lamination configuration, manufacturing process, and jig design. Balancing these factors required extensive experimentation in order to internalize the various parameters necessary to the final product. Then these factors were refined in design integration to find the proper balance and interplay between them.
