A support mechanism for supporting an object, such as a table, has at least four legs and an interconnection means connecting the legs. Each leg has a beam portion with an inner end and an outer end. The beam portion of each leg is connected to the interconnection means by a respective pivot having a pivot axis located between the inner and outer ends of the beam portion. Each respective pair of adjacent legs has a protrusion fixed to one of the legs of that pair of adjacent legs and extending from that one leg to act on the other leg of that pair of adjacent legs. In use, the outer end of the beam portion of one leg moves in an upwards direction and the outer end of the beam portions of the adjacent legs moves in a downwards direction to accommodate uneven ground surfaces.
