About Bespoke Furniture
At IYB., our approach to furniture-making is to design optimal specifications tailored to the environment, the client’s physique, and the intended use-and to carefully craft each piece. We analyze spatial conditions and the client's needs in detail, optimizing each chair down to its structure, choice of materials, and the tension of its upholstery. It is this fusion of precision and sensibility - a quality unattainable through mass production - that defines the essence of IYB.’s Bespoke Furniture.

IYB. Bespoke
Artisan Craftsmanship
The finish of the upholstery defines both the comfort and the form of a piece. At IYB., our artisans interpret the character of each fabric, adjusting tension and seam lines through the sensitivity of their hands.Within millimeter-level precision, they imbue each piece with a gentle expression.This hand-based technique ensures both consistent quality and structural beauty.

Product’s Detail
Human Scale
Just as each person’s physique, posture, and way of living is unique, so too is their sense of what feels “just right” in furniture.At IYB., we fine-tune details-such as adjusting the height of a chair’s legs by a few centimeters, or designing the depth of a sofa to suit the space-creating a natural harmony between the user and the furniture.


Material & Color
Covering and Materials
At IYB., materials are carefully selected from multiple perspectives-texture, color, and durability. We propose the most suitable fabrics from domestic and international manufacturers that best suit each space, purpose, and budget. Beyond functionality, we design for how the material interacts with light and touch - pursuing a quiet, natural beauty of materials that blends seamlessly into everyday life.

The Beauty of Details
Details such as stitching and piping not only support the structure but also shape the character of each piece. At IYB., every angle, width, and thread thickness is precisely considered to achieve perfect balance. It is through this accumulation of precise handcraft that a calm, yet powerful and distinctive presence emerges.

The Art of Comfort
Each IYB. chairs are designed by adjusting the density and layering of urethane to match the body's center of gravity and posture. By exploring the boundary between firmness and softness, we pursue a natural sense of comfort. Where rational design meets the intuition of craftsmanship, a serene comfort emerges-one that embraces both body and mind. Within this finely tuned comfort lies the philosophy of IYB.
