TETRA Seat is a playful, modular seating system inspired by Tetris, designed to empower children to build, play, and recline in creative configurations. Its soft, upholstered blocks can be rearranged into chairs, sofas, or floor mats—supporting both imaginative play and restful comfort. Crafted with ergonomic scale, safety, and a palette of calming, earthy tones, TETRA encourages sensory engagement and spatial exploration. A winning design in the 2025 SIT Furniture Awards, it bridges fun and functionality in dynamic kids’ environments.
