From a community member:
I hope to travel again next year after all this covid and was thinking of a question.
All I have seen are for at-home use, BUT wonder if anyone thought of manufacturing one out of Plastic/Perspex that is unbreakable but folds in half to fit into a travel hold all and is light enough not to add any significant weight.
I travel with a tour company but have had the embarrassment of dropping my Breakfast Plate on the floor in front of my new fellow passengers as being a one leg amputee with no right leg, hip or pelvis balancing a plate to the table is a disaster. I would love to be able to take a tray on tour so i can use it as and when and wondered if that was possible.
Just a thought from a frustrated 81-year-old wheelchair traveler.
