A cradle supports a joist across two contact points and is designed for very low-profile applications — starting at just 10mm. It is ideal for patio overlays and renovation projects where minimal build-up height is critical. A pedestal is a single-column support that carries the load on a central head, with height adjustment from 23mm up to 975mm (and beyond with extension pads). Both use self-levelling heads and are compatible with the same range of surface types.
