It is common today to find in Havana areas plastic patio chairs corrected by their users; I am referring to the chairs known as monobloc. We know in Cuba and all over the world that these chairs will break. Its structural rigidity has been sacrificed for its production cost, stackability, lightness and ergonomics. The price of such a chair in Cuba is around the average salary. When you buy it, you must make some structural corrections before using it if you want it to be profitable. They look like repaired chairs, but they are corrected chairs. Wooden strips, ropes, adhesive tape, connect and reinforce their legs. There is such a diversity of solutions that the gap that fragility opens in the chair operates as a global vector for a multiplicity of local ideas.
