a) Sofa in the Bone Room
In Tobe Hooper's movie Texas Chainsaw Massacre released in 1974, in the main house featured in the movie there in a place often referred to as the Bone Room which featured technological junk, feathers, a caged chicken, as well and ornaments and furnishings made from animal and human bones.

The camera creeps along the skeleton of a foot that leads up  to the arm rest of a very crude sofa made with bones, some of which are noticeably human, such as the human feet, the arms along the arms and a human skull fixed on top of the centre.

This film Dan O'Bannon introduced to Ridley Scott and it served as a major inspiration for the Alien film as it was being made.
