A transportable adjustable seat assembly comprising, upper, lower and intermediate sleeves having telescopic interconnections, a seat on the upper sleeve transporting structure including wheels carried by the lower sleeve and adjustable locking elements associated with at least two of the sleeves for locking said two sleeves in selected positions of vertical height adjustment. st end of said outer legs engaged on the underside of said seat, and pivotal movement of said inner and outer legs is prevented; and to lower said chair to a rocking chair configuration, said hooks of said latch members are disengaged from said arcuate catch elements and as said chair is lowered, said outer legs pivot about their pivot connection with said lateral side members, and said inner and outer legs pivot about their said mutual pivot connection in a scissors fashion and said inner and outer legs form rockers with said curved bottom of said lateral side members resting on a curved top surface of said inner legs and said outer legs disposed parallel with said inner legs. 2. The chair according to claim 1, wherein each said link member is pivotally and movably connected at its said first end to a respective said latch member intermediate said latch member forward end and rear end to allow said latch member to pivot a short distance relative to said link as said hook is engaged and disengaged with said arcuate catch element. 3. The chair according to claim 1, wherein said depending laterally opposed vertical legs are spaced inwardly from lateral sides of said seat; and in said raised high chair configuration, a first end of each of said outer legs is engaged on the underside of said seat, and an upper portion of each of said outer legs is disposed laterally adjacent to said vertical legs, such that a forward portion of said seat is disposed between said upper portion of said outer legs to provide stable support. 4. The chair according to claim 1, wherein said manual latch release means comprises a rod extending slidably through an eye secured to said chair having a lower end pivotally connected with said transverse rung and a knob fixed to an upper end above said eye; and a compression spring mounted on said rod having a first end fixed to said rod and a second end biased against said eye to normally urge said transverse rung and said latch member rear ends downwardly under spring pressure; and as said chair is raised from said rocking chair configuration to said high chair configuration, said first ends of said inner legs pass forwardly beneath said hooks of said latch members and an outer surface of said arcuate catch elements slides forwardly against an underside of said hooks, raising said latch member rear ends said transverse rung upwardly against the pressure of said spring, and as a back end of said arcuate catch elements clears the underside of said hooks, the spring pressure causes said hooks to snap downwardly and engage said arcuate catch elements; and said latch members are manually disengaged from said arcuate catch elements by pulling said rod upward against the pressure of said spring such that said transverse rung and said rear ends of said latch members are pivoted upwardly in an arc and said hooks become disengaged from said back end of said arcuate catch elements to release said first end of said inner legs. 5. The chair according to claim 1, further comprising: a pair of generally L-shaped arms pivotally connected at upper ends to lateral sides of said back rest having lower ends extending forwardly laterally adjacent to said arm rests; and a generally rectangular tray secured transversely across a top forward portion of said lower ends; said L-shaped arms and said tray being pivotal upward and rearward to permit access to said seat.
