Pump assembly for a chair

A portable computer workstation 100 contains a base portion 1010, a wheel system 350, 510 attached to the base portion 1010, and a transport member 150. The transport member 150 has a first end portion and a second portion. The first end portion of the transport member has a handle and the second end portion is coupled to the base portion 1010. The transport member 150 can be moved up and down from the base portion. The transport member 150 is used to pull the suitcase 150 and roll it about. The transport member 150 is also used to hold a tray upon which a portable computer 820 is secured and used. The computer workstation/suitcase 100 contains two sets of wheels 350, 510 on the base portion. One set of wheels 350, 510 is attached adjacent the other. Thus, the suitcase can be rolled in multiple directions. When the suitcase 100 is transformed into a computer workstation 100, several support members 330, 350 flare out from the base portion 1010. These support members 330, 350 provide additional support and stability for the computer workstation 100. Also, the computer workstation 100 provides the convenience of several computer peripherals such as, power connection extension cords 1130, phone line extension cables 1140, cellular phone, etc. The invention can be use as a suitcase 100, a transportable portable computer workstation 100, or both.
