Abstract: An activity board assembly (1) including; a board (2) having an upper surface (3) for supporting a user (46), a base portion (4) and a resilient support member (5) having an upper and a lower distal end, said upper end being connected to an underside of the board and the lower distal end being connected to the base portion (4), characterised in that the board (2) is rotatable with respect to the base portion (4) about; a first axis in a plane substantially orthogonal with the upper surface (3) of the board and/or the base portion (4); a second axis substantially orthogonal to the first axis and substantially parallel to the upper surface (3) of the board and/or the base portion (4); a third axis orthogonal to both the first and second axis; the connection between the resilient support member (5) and the base portion (4) being configured to prevent linear movement with respect to each other.
