leg arrangement 14 comprises twolegs 28 which converge to meet at an in use uppercurved section 30. Across member 32 extends between thelegs 28, generally midway along their length, to provide strength to the leg arrangement and to prevent thelegs 28 from splaying apart, in use. The cross member extends generally perpendicular from the plane of thelegs 28 to present a support for the seat as will be explained. Each leg arrangement is generally in the form of an A-frame. - The
leg arrangement 14 is of tubular construction and is formed from a suitably strong and rigid material to provide for appropriate support to theseat 12 during use and also to enable the push-fit location thereof in the seat as will be described. - To locate a
leg arrangement 14 in arespective locating recess 26 involves introducing aleg arrangement 14 to locating recess generally from a direction beneath theseat 12 and pushing theleg arrangement 14 up into therecess 26 to locate within therecess 26 and to be received therein as shown in Fig. 3a - 3d. Generally in the direction of the plane of theside 24, the shape of the locatingrecess 26 is closely similar to that of the external shape of theupper portion 34 of theleg arrangement 14 which is received in therecess 26, whereby to prevent any rocking movement between theseat 12 and theleg arrangement 14 in the direction of the plane of theside 24 and theleg arrangement 14. - The locating
