From Margo Milne via email:
It’s a bag with a smooth surface on one side and a bean-bag on the other, making it a true multipurpose item.
My Trabasack is essential to me, as a bag, a wheelchair lap tray, and for a million and one uses at home and outside. It’s well-designed and “non-clinical” in looks, comfortable and simple to use, and robust and easy-to-clean.
I love my Trabasack!
