Design Interview

What is the main principle, idea and inspiration behind your design?

The Aeriform Armchair was born from a desire to capture the quiet grace of bird wings, unfolding mid-flight. I imagined a form that could feel like an embrace, soft yet powerful, sculptural yet inviting. Designed entirely in virtual reality, I sculpted it as if drawing with ribbon in the air, free from gravity and constraints.

I was also heavily influenced by Pierre Paulin’s Ribbon Chair, and I aimed to build on that legacy by designing something even more bold and imposing. But aesthetics weren’t everything—I went through several physical prototypes and ergonomic jigs to make sure the chair was actually comfortable in real use. I wanted it to be both a centerpiece and a genuinely functional seat.

What has been your main focus in designing this work? Especially what did you want to achieve?

With this design, my main focus was to create a seamless blend of sculptural elegance and genuine comfort. I wanted the Aeriform Armchair to feel like a statement. Bold, confident, and eye-catching, yet also be the kind of chair you could sink into for hours without a second thought.

Too often, showpieces sacrifice usability for aesthetics. I didn’t want that. I set out to prove that an iconic form can still offer an inviting, ergonomic experience. The goal was to strike that elusive balance: a chair that dominates a room without demanding constant attention, that looks like art but functions like a daily essential.

What are your future plans for this award winning design?

My goal is to bring the Aeriform Armchair into the real world. Not just as a prototype or concept, but as a product available to those who appreciate bold, sculptural design. I’m currently looking for a luxury furniture manufacturer who sees its potential and shares the ambition to develop a production-ready version together.

There are still things I wasn’t able to fully realize on my own, like wrapping it in high-quality leather or crafting a cast chromed base, but with the right partner, I believe we can elevate it to its full potential. My hope is for the Aeriform to find its place among the icons: to be mentioned in the same breath as the Egg Chair, the Ribbon Chair, or the Papa Bear. I know it’s an ambitious goal, but I believe in the design, and I believe there’s a place for it in the canon of timeless furniture.

Grand Interview

Your innovative approach to designing the Aeriform Armchair entirely within virtual reality is fascinating - could you elaborate on how this digital creation process influenced the final ergonomic solutions and flowing form?

I had experimented with virtual reality design before, but never on something that would eventually become a fully realized physical product. So in many ways, this was new ground for me. I wanted to tie the virtual and physical worlds together in a way that felt natural, so I built an adjustable jig in real life that I could sit in and measure from. I then traced that jig in VR to use as a reference to keep the scale, ergonomics, and seating posture consistent with what a person would experience. With every iteration, I would sit in the jig, position the model exactly where it was and look around in VR, imagining how the chair would feel around me.At first, I tried sketching some bold concepts on paper and recreating them in VR, but they didn’t quite translate. The lines I liked on paper didn’t feel right in 3D space. So I flipped the process. Instead of translating sketches, I started sketching freehand directly in VR. The organic quality of modeling in virtual space felt just right. Shapes felt more sculptural and alive. One of the early sketches came from simply manipulating a flat plane between my hands, bending it like a ribbon suspended in air. That moment led to the core visual language of the armchair.From there, I refined the Sub-D surfaces until I had a volume that not only looked bold but also supported the human body well. I still used planar views on paper to cross-check and refine details, but most of the shaping happened in VR. Toward the end of the process, I paid a lot of attention to surfacing details using zebra mapping and reflection tests to refine the curves to a level that felt natural and perfected. It was a process of constant iteration, but VR gave me the creative freedom to sculpt the form in a way that traditional tools never could.

The Aeriform Armchair's inspiration from bird wings and Pierre Paulin's Ribbon Chair presents an intriguing evolution - how did you transform these influences into your own distinctive vision while ensuring optimal comfort across various seating positions?

I admire the aesthetics of Pierre Paulin’s Ribbon Chair, and with the Aeriform Armchair, I wanted to pay homage to that classic while creating something distinctly my own. One of my main goals was to design a chair that’s not just sculptural but truly comfortable. Something you could sit in for hours, whether you're reading, relaxing, or scrolling on your phone.In my observations and design lectures, I learned that seating is inherently dynamic. We shift positions constantly, so I knew I wanted to create something that supports movement. My early sketches tried to blend the posture of upright seating with the laid back ergonomics of a lounge chair. That didn’t quite work as I envisioned, but it led me to realize how often I sit sideways in chairs. So I made that a central feature.This is where the influence of bird wings came in. I imagined large sweeping forms that would gently envelop the sitter, creating a sense of both security and privacy, while offering support for the back and head when sitting sideways. My initial drawings leaned more literally into wings and even had feather motifs, but as the design evolved, I stripped those elements back and embraced a purer, smoother form. The aerodynamic qualities remained as a subtle nod now visible in the cross sections - hence the name Aeriform.

Your research revealed limitations in traditional anthropometric studies regarding comfort - could you share how the special testing jig you constructed helped bridge this gap in developing the Aeriform Armchair's dynamic seating experience?

Yes, traditional anthropometric studies mostly treat sitting as a two dimensional problem by measuring backrest angles, seat depth, and so on. But that approach feels inherently flawed. Humans are built to move. Even the most “ergonomic” position becomes uncomfortable when you’re forced to hold it for too long. Static sitting leads to fatigue, stiffness and poor circulation. It doesn’t reflect how we actually use furniture.During my research, I came across only one book that acknowledged this and tried to go beyond the static model. It introduced the idea of sitting as a dynamic, time based experience, so more like four dimensions: X, Y, Z, and time. It also provided valuable information about cushioning and how materials affect long term comfort. But when it came to supporting varied seating positions, it still fell short.That’s why I built my testing jig. It was a simple frame of two standing panels with a grid of holes, steel pipes and adjustable seat and backrest panels which attach to the pipes. This allowed me to test a wide range of angles and heights in real life. I mapped out the primary upright position as well as more relaxed, sideways poses for secondary position. I tested it on myself and others, took measurements, averaged to be able to fit more people, and then translated those measurements into virtual reality. Essentially, I created a kind of ergonomic skeleton inside VR that I could sculpt around. And it worked beautifully.

Production Technology
The prototype started with a foam core, CNC-milled from XPS foam and assembled with adhesive foam. It was sanded smooth, coated with epoxy resin, and layered with fiberglass for a strong shell. The base and legs were laser-cut steel, welded, and finished with a 3D-printed shell. The frame was padded with foam and batting, then covered with a precisely cut and sewn fabric. Finally, the chair was assembled with its base, lazy Susan, and headrest cushions.
Design Challenge
Main challenge was the lack of proper studies of comfort in anthropometric books. While ergonomy is well documented, there isn't much information abou comfort. Ergonomy looks at things from 2 dimensions, and while it's a good start, seating is usually a dynamic activity for the body and needs to be studied in 3-4 dimensions. Thats why personal testing on the jig was conducted.
Research
Research started with ergonomics. Drawing inspiration from anthropometry books and personal tests on a special jig constructed to allow for change in seat and backrest positioning and change of angles. From that data was constructed a 3D "skeleton" of the armchair and then iterations took place in virtual reality. Testing was performed with people ages 18-60 as the main target demographic. First 1:1 model was made out of polystyrene and tested as well. Drawing conclusion on overall dimensions.
Inspiration
The Aeriform Armchair draws inspiration from the natural elegance of bird wings, evoking the feeling of an embrace. Designed entirely within virtual reality, the form was conceived from a flowing, ribbon like structure suspended in space. Influenced by Pierre Paulin’s Ribbon Chair, the design was further refined to create a more imposing and luxurious piece. Extensive prototyping and ergonomic testing via jigs and models were undertaken to ensure optimal comfort across various seating angles.
Project Duration
Work on the project began in December 2023 and came to conclusion in June 2024 as the main focus of the diploma project.
Operation Flow
The Armchair is designed for ease and comfort, promoting a natural seating posture. Its flowing structure supports the body, distributing weight evenly and allowing various sitting angles, such as sideways or with legs crossed. No complex adjustments are needed; interaction is intuitive. A Lazy Susan facilitates movement and fidgeting, while the springy base offers a rocking motion. The design combines aesthetic elegance with practical functionality for a comfortable and inviting experience.
