Tomoko Azumi, with the help from the craftsmen at Benchmark, used thin slats of American red oak, steam-bent into shape to create the boat structure and placed an X in the centre to capture all of the elements Kwei-Armah desired. By using different lengths of timber, Tomoko has lightened the structure at the top and ensures privacy for the person sitting in the seat. A boat varnish was used for the finish of the red oak.
