This is a bit like saying that an ill-fitting bicycle can cause more harm than good: technically true but missing the point. Sometimes it's valuable to have a cheap bicycle that you can expose to the elements without worrying about messing up the high-end components on your more expensive bike.

These seem to be mainly intended as secondary chairs or for part-time wheelchair users, rather than as primary chairs. My wife has three wheelchairs and I can see a case for buying one of these as her fourth.

Mind you, the situation with electric wheelchairs is very different. Many electric wheelchair users are at elevated risk of pressure sores, may not be able to get in and out or reposition themselves independently, etc. The profit margins on these chairs are still inexcusable, but the amount of custom fitting and memory foam everything is warranted because the user may well be in this chair, in that position all day every day. The cupholder and the umbrella mount are must-have accessories.
