The D*Table

In 1903, Henry Ernest Dudeney stunned the mathematical world with his ‘Haberdasher’s Puzzle’, which proved how to turn a perfect equilateral triangle into a perfect square. The artist and sculptor Maty Grünberg utilised this mathematical principle to design an occasional table especially for Aram’s 23rd anniversary celebrations in 1987, which he called the D*Table.

Now, in Aram’s 50th anniversary year, Maty’s son David ben-Grünberg and his business partner Daniel Woolfson have manufactured the D*Table with up-to-date materials and we are delighted to present this design exclusively to the UK market. Manufactured to the highest standards in a Danish factory (used by Fritz Hansen) from engineered carb 2 timber, the table’s surface is protected by a 0.5mm aluminium layer which is then painted with a non-toxic semi-soft matt finish in either black or white.

Each section swivels on 50mm rubber castors; for stability, we recommend that the sections are not used separately but are always connected by their hinges. The sections provide a variety of storage spaces – shelves, containers, a magazine rack and even a bottle holder. Also provided is a set of four coloured coasters echoing the shape of each section.
