Alexander Lotersztain
This collection of seating, titled QTZ, is inspired by the naturally occurring geometric forms of Quartz. Designed by Derlot’s Alexander Lotersztain, it reflects the prismatic beauty and semi-precious qualities of one of the Earth’s most abundant minerals.
Each QTZ piece is available in a range of powder coat finishes and is manufactured in stainless steel using advanced technologies and craftsmanship to ensure they meet the highest standards.
