A drink table beside a camp chair
Check the seated reach and ground together.

Sit before positioning
Low chairs can make a tall table awkward. Place the drink where you can grasp it without pulling yourself forward.
Check the table frame
Lock folding parts as the table maker directs. A sagging fabric top is not equivalent to a rigid level surface.
Leave an exit
Keep the table clear of the way you stand up and of guy lines or camp footpaths.
