For over 50 years, the Bontempi brand has been synonymous with furniture that combines quality and aesthetics with functionality and comfort - designed and manufactured in Italy. Technology, design, functionality and material innovation are the guiding principles of the Bontempi collection. One such innovation is the Bontempi Super table tops. They are produced by combining float glass with porcelain stoneware in a ceramic or marble look. This creates table tops with an extremely high level of resistance.
