QTZ by Alexander Lotersztain for Derlot
Updated: Jan 26, 2020

The design of QTZ chair is inspired by the naturally occurring geometric forms of Quartz. This limited edition collection of seating elements reflects the prismatic beauty and semi-precious qualities of what is amongst the Earth's most abundant minerals.
The Limited concept was born of Alexander Lotersztain's passion for materials, technologies and craftsmanship. It serves as an experiment to study the boundaries of aesthetics and functional innovation.


Each QTZ element is available in a range of finishes and is manufactured in stainless steel using advanced technologies and craftsmanship to insure they meet the highest standards.
Also the QTZ CONCRETE manufactured by IVANKA made its prototype preview at this year's Salone del Mobile in Milan.
Each piece is produced in the finest materials, personally overseen by the designer to insure the highest standards of craftsmanship are met. They are then individually numbered and sold with a certificate of authenticity, signed by Alexander Lotersztain.
