Thule Sleek is a four-wheeled pushchair which may be used from birth onward and later adapted variably again and again to the development of the child. The Thule Sleek chassis can be configured as a bassinet, a baby seat or a normal, full-sized pushchair seat. If required, it can be extended by adding a sibling seat or glider board. Its light, compact construction makes the pushchair very manoeuvrable. It may also be folded up to save space and is simple to transport.
