In higher category theory, we use fibrations to model presheaves. In this paper we introduce a new method to build such fibrations. Concretely, for suitable reflective subcategories of simplicial spaces, we build fibrations that model presheaves valued in that subcategory. Using this we can build Cartesian fibrations, but we can also model presheaves valued in Segal spaces. Additionally, using this new approach, we define representable Cartesian fibrations, generalizing representable presheaves valued in spaces, and show they have similar properties.
