This study explores how actors deal with normative complexity in the design and implementation of practices of preventative care. Previous studies have identified conflicting (e)valuations of prevention within health care at large, but little empirical research describes how these conflicts are resolved in day-to-day interactions. Zooming in on the work of a single actor, our ethnographic study describes a Dutch psychiatrist developing a novel type of hospital bed that provides preventative psychiatric care for women in the post-partum period. Drawing on pragmatic sociology of justification, we construe 'beds'-and the time, people and resources they represent-as points of convergence between conflicting valuations of care. The results show that embedded modes of valuation in a curative hospital setting generate significant normative complexity during implementation. We identify three main strategies through which normative complexity is managed: (a) translating between different modes of valuing prevention, (b) compromising in (material) design of care beds and (c) transcending embedded valuations through moral appeals. By showing the normative complexity of
