MAINSOFA
3D modular sofa configurator with dynamic section assembly and textile visualization


OBJECTIVE
The goal for the Main Sofa project was to provide a seamless digital experience for designing custom modular furniture. The challenge was to create an intuitive interface where users could build complex seating arrangements from individual components while maintaining strict structural rules.
We needed a solution that would allow customers to experiment with different base models and fabric textures, receiving instant visual and financial feedback as they scaled their configuration.
SOLUTION
We engineered an interactive, step-based 3D configurator built on a modular "snap-to-fit" logic. The system allows users to define a core interior style and then physically build their sofa by dragging and dropping various modules - such as Straight, Left/Right sections, and Poufs - into a unified scene.
To enhance user interaction, we implemented custom UI triggers, such as dynamic toggles for opening or closing armrests, all while maintaining a real-time connection to a dynamic pricing engine and a direct-to-cart checkout pipeline.
KEY FEATURES
01
LOGIC-BASED SECTION
The configurator utilizes a "snap-to-fit" logic where users define a core interior style as the structural foundation for their sofa. The system ensures that all chosen sections remain architecturally consistent with the selected base model while users scale their design.
02
FABRIC & TEXTURE MAPPING
A high-fidelity style engine allows users to instantly swap between a vast library of premium fabrics. The 3D model applies these textures in real-time with accurate light behavior, helping customers evaluate how different colors and materials, from neutrals to vibrant tones, impact their interior design.
03
DYNAMIC SCENE MANIPULATION
Users have total creative control over the arrangement, with the ability to freely add, delete, or duplicate modules like Straight sections and Poufs. The interface supports active interaction, allowing customers to rotate elements and use specialized triggers to Open or Close armrests, providing a hands-on feel for the sofa's spatial versatility.

THE RESULT
By allowing users to take full control of the design process - from structural assembly to final material selection - the brand reduced the sales barrier for high-ticket modular items.
The integration of life-size AR allows customers to virtually place their unique, modular creations directly into their living rooms to verify the footprint and aesthetic fit. This combination of automated pricing, precise visualization, and spatial validation ensured a confident path to purchase, resulting in a streamlined experience from custom design to finalized order.
