Described reversible chair, wherein, described seat support is set to dichotomous saddle structure.
Described reversible chair, wherein, also comprises workbench, and described workbench is dismountable to be arranged on chair back connecting rod.
Described reversible chair, wherein, described seat support also comprises chassis, and described chassis is fixedly connected with seat support, and described chassis and back shaft are rotatably connected.
Described reversible chair, wherein, the width of described chair back connecting rod is set to: 15 ~ 30 centimetres
Described reversible chair, wherein, described seat surface is provided with air-vent.
Described reversible chair, wherein, also comprises load carrier, and described back shaft is rotatable and be telescopicly arranged on load carrier.
Shown reversible chair, wherein, be provided with rotary switch outside described chair back connecting rod, described workbench is provided with installing hole, and described chair back connecting rod and workbench are removably connected by rotary switch.
In the utility model, chair has forward and backward two kinds of sitting posture modes, the pressure dissipation that waist and buttocks under sitting posture state can bear by the saddle type structural design of seat support is on thigh, and the structure of saddle type effectively can cushion and discharge the interaction force between thigh and seat support, can keep sitting posture for a long time.The air-vent that seat surface is arranged contributes to the heat radiation of seat area, keeps clean dry and comfortable.When user sits forward for a long time, can sit towards the metathorax arm-chair back of the body by turning chair seat surface, not only discharge backside pressure calm nerves system but also spinal load can be alleviated, in addition, the chair back is also provided with detachable workbench, to work convenient during recoil, solve the technical problem that existing chair is uncomfortable, cannot adjust sitting posture.
