My interest went about relaxation, rest and sleep. Because those are not activities that were studied in the existence of spatial objects or only to answer to a physiological need.

During my researches, I based myself upon the ultimate relaxation position which is a notion developed by Story Musgrave, American astronaut and artist, who talked about his own experience with weightlessness and particularly about the inherent positions only possible in this status. The ultimate relaxation position is only possible when all muscles are completely relaxed and no exterior force applied on the body. In this situation, one does not feel his own body in surrounding space anymore.
Therefore, it was my starting point: position and practice. When to use this daytime relaxation device? To still employ terrestrial vocabulary: this device is the synonym of the sofa.
That is to say a solo relaxation surface but also a communication and human interactions device.
