The form of the 111 Navy Chair (2010) derives directly from the legendary 1006 Navy Chair, which was designed for use on WWII submarines, where durability was vital. A key component of that strength, carried over to the 111, are leg stretchers, which typically are not found on plastic chairs and give the 111 a sturdiness to stand up to frequent use. The Navy Chair design constitutes proprietary Trade Dress. This is the authentic 111 Navy Chair by Emeco. Eco-Friendly Description: Certified Intertek Clean Air GOLD.
