Query: My short wife blessing

My wife, who is only 5'1" and has trouble in a world of furniture always being for a more normal sized person. And my being 6'3" and having furniture around that fits me, really creates a situation of need for these type of back rests. We have 3 in various colors. She uses one in the lazy boy, office chair and at the dinner table, makes her feet touch the floor and feel under control.
