A portable chair assembly including first and second chairs and a movable support frame, each chair having a seat and a backrest. Each backrest is adapted (i) to be folded by a user onto its respective seat in a collapsed position and (ii) to be moved away from that seat into a deployed position. The support frame has at least two frame segments, each frame segment having an upper frame portion supporting one of the backrests at pivotable connections with the upper backrest portion of that backrest, and each frame segment being joined to the other frame segment by an upper joint member and a lower joint member. At least one angle member is provided per chair, a backrest end portion of each angle member being fixedly or removably secured to one of the first chair backrest and the second chair backrest, and a frame portion of each angle member restricting movement of the support frame away from the seats to establish a maximum deployment angle in the deployed position. A container, having an opening, is positioned between the first chair seat and the second chair seat. A blanket is placeable through the opening into the container to be stored therein in the collapsed position and deployable from the container in the deployed position.

A seating device (1) with a reclining function comprising a back frame (4) which provides a significant reduction in the complexity of the system, at the same time as it gives the user increased comfort both in an upright (sitting) position and in a reclining position. The back frame (4) comprises in particular two types of resilient elements (7, 8) and rotatable fasteners (6) which provide adaptive support to the lumbar spine in both a sitting and reclining position.
