Heimess, Goki and Holztiger are trademarked and manufactured by Gollnest & Kiesel, a north German company that produces cherrywood toys; started in 1981 with the aim of making 100% German ethical wooden toys. The toys are manufactured in their factory in Vaihingen near Stuttgart with wood sustainably sourced from local surrounding forests, not far from Stuttgart. The Heimess Nature Touch range and Goki Nature range use a natural thermal colouring process instead of using dyes, giving this range their distinctive two-tone wood colouring.  Paints used are water based dyes. Every year Gollnest & Kiesel donate a new forest in Schleswig-Holstein, which is currently the least forested state. They do this by planting a tree for every newborn baby born in the state, under the company moto “a tree for every newborn in Schleswig-Holstein”. Since 2004 over 400,000 trees have been planted in new forests.
