A seat, particularly a rocking chair, includes a frame, a seat surface and a backrest. The frame includes two lower frame parts extending forward from the backrest and each having a curved progression which is convex in downward direction. The seat can have with stop members arranged close to a front outer end and/or close to a rear outer end of each lower frame part. The stop members can be resiliently deformable. Additionally or alternatively the lower frame parts can each be covered on an underside thereof with a resilient and/or damping material. This resilient and/or damping material can comprise a shaped part connected to the relevant frame part. The stop members can be integrated in the shaped part. A stop member and a shaped part intended for application in such a seat.

An exercise chair includes a chair frame, and a base fixed with the chair frame that is adapted to support the exercise chair on a floor surface. The base and chair frame have a plurality of anchors projecting away therefrom. A cushion may cover at least a portion of the frame. Multiple resistance bands each have multiple longitudinal slots therethrough, each adapted for selective fixing with any of the anchor knobs or several attachable exercise devices. In use, with the person seated in the chair and the chair resting on the support surface, one or two of the resistance bands can be fixed with any of the anchor knobs, so that the person can exercise by pushing and/or pulling the at least one resistance band. Different types of attachments are included for exercising varying muscle groups.
