The leg has an extruded cylindrical profile (1) whose upper end is provided with a metallic grooved insert (2). The insert is threaded in its external part in a manner to assure the fixation with a base or a foundation of a rest equipment i.e. mattress. A lower end of the profile receives a supporting cap (3) fixed with a rod (4). The profile is formed by co-extrusion with a core made of recyclable material, where the material contains an expansion agent. |
