Multi-functional Bench (Couch)

This bench is "multi-functional" as it is made up of 16 pieces, each can rotate freely from the "Chair" position to the "Armrest" position. This design isn't actually my idea; I modified the original one - which I cannot trace its owner - and made it possible to be manufactured as the original one had many designing mistakes. This is the original https://grabcad.com/library/multifunctional-couch-1, but its REAL owner is still unknown. Modelled with SolidWorks 2016 Rendered with PhotoView 360 Gifs made with PhotoScape V3.7
