Ahrend601 Bench There are three versions of the 601 Bench available: one made from recycled compressed beech hardwood that is 100 percent recyclable; a second made from partially recycled aluminum alloy; and an outdoor version of the recycled compressed beech offering that is treated with Belmadur solution, a water-based weatherproof treatment. The sloping, low-scale design has no visible seams, bolts, or screws. Each piece is water-jet cut from a single rectangle of material that is then steam-bent into an outward curve. Complementary stools and occasional tables are available. ahrend.com; 973.652.4357.
