Multi-pivot seat base assembly

A multi-pivot seat base assembly including:

• a floor-mountable element;
• a proximate arm having proximate and distal ends;
• the proximate arm being mounted to the floor-mountable element via its proximate end for first relative pivotal movement between the proximate arm and the floor-mountable element;
• a distal arm having proximate and distal ends;
• the distal arm being mounted via its proximate end to the distal end of the proximate arm for second relative pivotal movement between the distal and proximate arms;
• a seat-mounting element mounted to the distal arm at the distal end thereof for third relative pivotal movement between the distal arm and the seat mounting element;
• a first pivot locking assembly associated with the proximate arm and being so configured as to selectively prevent the first relative pivotal movement;
• a second pivot locking assembly associated with the distal arm and being so configured as to selectively prevent the third relative pivotal movement;
• and
• a third pivot locking assembly associated with one of the proximate and distal arms and being so configured as to selectively prevent the second relative pivotal movement.
