A cross rocking chair having a chair fabric, a seat frame assembly, a support frame assembly and connectors. The seat frame assembly has two cross tubes, two square seat frame armrest tubes and two backrest support tubes. A cushion and a backrest of the chair fabric are mounted at upper ends of the cross tubes and the backrest support tubes. The support frame assembly has two support frame units each having a support bottom tube. Rear ends of bottom tubes of the seat frame armrest tubes are bent upwards, and front ends of the bottom tubes are arranged on the support bottom tubes. Two ends of each connector are rotatably connected to the top of the bent rear end of the bottom tube of one seat frame armrest tube and the rear end of the corresponding support bottom tube.

Disclosed is a rocking cart table, which is moved forward/backward and in a seesaw manner by passenger's motion and thus can provide enjoyment following play through a rock to the passenger. The cart table comprises: a cart body installed on a rail and moved forward and backward by passenger's motion; a seesaw movement member moved in a seesaw manner by the passenger's motion; a table member; and a light-blocking member.

A chair support shell has an integral back portion, seat portion, and joining portion between the back portion and the seat portion. At least a major portion of the support shell comprises a compliant structure, the compliant structure having a plurality of cells interconnected by a plurality of resilient members. The compliant structure provides compliance in the seat portion, compliance in the back portion, and compliance in the joining portion. The compliant structure enables recline of the back portion relative to the seat portion.
