A steerable trolley, typically a shopping trolley, comprises two or more pivotable wheels and the steering mechanism comprising communication means between a driving wheel and corresponding driven wheel, the communication means being operable such that pivotal movement of the said driving wheel about a substantially vertical axis acts to produce a pivotal movement of the said corresponding driven wheel, wherein when the driving wheel is a rear wheel the driven wheel is a front wheel and vice versa. Advantageously only one and preferably, the outer of the driving wheels acts to produce the pivotal movement of its corresponding driven wheel during cornering of the trolley. An override mechanism for user disengagement or disengagement when the trolley is stacked is also provided. An arcuate handle bar and side bars may also be provided. Ease of manoeuvrability is assisted by differential offsets in the drive and driven wheels.
