This is a competition which requires the design of a bench where we needed to find a form that could be repeated and flexibly. The idea was to create a form of 60x60 cm (which is the seat of a person according to the standards) with a backrest retractable, in order to use it and not depending on the wishes of the person. The backrests can be pulled up and down from both sides depending on where the person sits. With numerous neighboring modules, you can create the benches in the shape that you prefer. There are also modules that can be used for green or to the garbage for greater urban sustainability. On the right are some examples of benches and the detail of the back that disappears under the seat. 
The materials are of the bench for the structural steel and wood for seating.
