When a new style of seat suddenly appeared on Mexico City's metro system, it was labelled as inappropriate, uncomfortable, humiliating and embarrassing.
It was supposed to be.The seat, moulded to include a protruding penis and chest, was designed to highlight sexual harassment experienced by female passengers.
The explanation next to the men-only label read: "It is uncomfortable to sit here, but that is nothing compared to the sexual violence that women suffer on their daily journeys."
The seat is not a permanent fixture, but part of a campaign called #NoEsDeHombres, which aimed to highlight sexual harassment on public transport. But the response has been mixed.
