Aurora Tre has an enveloping shape that is formed by the curvature of the structure, whose parts are made in birch plywood. Its softness comes from the internal padding with polyurethane foam of different densities and polyester wadding onto which Poltrona Frau's extraordinary artisans fix the upholstery with a sequence of stitches pulled one by one.

The bed can accommodate a large storage space, made accessible thanks to a device with gas springs and a single or double lifting mechanism. In the case of a single mechanism, the bed base is raised to an inclined position. Both mechanisms are equipped with a safety lock.
