This is like saying a $30 display off Aliexpress is better than a $1000 display from a high quality brand. The only metric it will be better on will be the price, everything else will be a ridiculous comparison.
Shipping makes them pretty consistently $116ish/piece until you hit negotiated shipping numbers.
They're also not the kind of wheelchair people are looking for if they're self mobile which is the kind of chair the article is reporting on. Those are made lighter and more resilient to stand up to being used by one person out in the world rolling themselves around.
> 1k$ is pretty steep.
It's not if you don't want to sacrifice quality, USA made is also a bonus. Kudos to JerryRigEverything.
Go for it bud
These are not the same class of products.
The alibaba ones are almost like disposable lower quality solutions, have textile backs, and are foldable, etc. which also have their places and uses eg. after disasters, mass depoyment, handout at hospitals as temporary solutions.
The product in the linked article is clearly a higher quality item intended for longer term use by a single person.
1k$ is the cost of a decent office work-chair from any well-established low-to-medium volume vendor, as context. For a small shop like this it is an okay price, abeit the sum being a lot for many especialy in a new situation where they are forced to a wheelchair. Mass production could probably drive it down a lot, but you need volume for that.
ps: with volume you can also better amortize the engineering costs, which can be significant even for stuff looking simple and easy to do for those who did not do it yet... or did (even significant, core) parts of the product development in a large established firm. I also started a product development for simple looking stuff that turned out to be a lot lot more work when not being done only as a hack/PoC, but developed to a product. I abandoned the product before going for the official certifications (FCC, CE, etc.). For medical equipment they probably also need to meet regulations.
