i mounted a table top rectangle bit of wood 1 1/2 x 4 foot on a swivel chair base with a clamp so i can sit back and swivel it and move it ware want it. The wheel base in abit to the left to give room for feet and is couter ballanced by a another bit of wood making the shorter side heavier
==L-------, technically its still a table with a cooler on it but i dont have to sit at a desk i sit ware i want comfy arm chair usually
oh it also goes up and down if i want to sit on the floor cusions.
You can buy swing arms that mount on the wall or floor or like me make ya own
or get a metal floor instlled and use shielded magnets underneath to make it float ware u want it
