HAI is a Japanese-inspired, adjustable shelving unit.
The shelves can be positioned freely according to the user’s needs. This is enabled by the zigzag structures in the vertical poles, which act as supports for the shelf brackets.
Without screws or cross braces, the structure gains its stability through angled vertical supports and a wedging principle created by the half-cut openings in the shelves.
Adjustable feet allow for levelling on uneven floors.
The poles are made from beechwood, while the shelves and their supports are made from solid ash.
I named the piece HAI – it is both the Japanese word for “hello” and the German word for shark. The cut-outs in the poles recall vertically arranged shark teeth.
Below you see shots of various views and details of the shelf.
