Tonelli Design is an Italian glass furniture manufacturer based in Pesaro (Province of Pesaro-Urbino, Marche), trading as T.D. s.r.l. The company was founded in the 1980s. CEO is Michele Gasperini. Tonelli revolutionised the sector with a proprietary technique: straight glass sheets are joined with a structural adhesive that preserves transparency and makes the joint stronger than the surrounding material.
The range covers tables, consoles, mirrors, bookshelves, lighting and accessories. The primary material is tempered extra-clear glass — free from the greenish tint of standard options — combined with wood, metal, fabric and leather. Some products use recycled glass; all are designed for disassembly. Design partnerships include Karim Rashid, Moe Design Lab, Isao Hosoe and Massimo Castagna. Tonelli products are specified in projects worldwide — for residential, office and contract environments.
For architects and planners who treat glass furniture as a design statement rather than a compromise, Tonelli Design sets the industry benchmark. The combination of industrial precision and artisan finishing makes the company an exceptional player in the international furniture market.
