“human oriented” means it can be adjusted, once or twice, but it is a pain to open/close too often. So it end up there, in a corner, half deployed, taking space and unused – too much pain to adjust all R/L joints at same angle, take some attempts to level it in a new setting… I should fold it back under the bed, but then it will stay there forever..
