This text is an ethnographic account of a singular, Barcelona-based activist endeavour called En torno a la silla (ETS): a do-it-yourself and open design and making collective engaging in a very peculiar form of accessibility politics beyond a ‘disability rights’ framework. In it, I entangle intimately with ETS’s relational interventions, in the form of making and documentation processes. What animates me is a political engagement with the practice of ‘re-description’, paying attention to the singularity of what relational vocabularies and practices bring to the fore. In describing the context of its appearance, as well as several of the collective’s endeavours, I address ETS’s relational register. Rather than being a clear-cut activist group with the aim of materialising the ‘inclusion’ of ‘disabled people’ through ‘technical aids’, ETS engaged in producing what they called ‘technologies of friendship’: frail and careful material explorations opening up interstitial relational spaces of ‘mutual access’ between bodily diverse people. Through circulating tutorials, poetic accounts, digitally and in workshops and presentations, ETS’s technologies of friendship became also ways of addressing how relations can be materialised and reflexively described, making available in its wake ways to re-enact them. Thus it produced an inspiring ‘how to’ accessibility politics: a material-political concern with the speculative opening up and materialisation of conditions for the very happening of relations, relating at the hinges of unrelatability.
