First off, stealing is not allowed. I don't know the finer details of intellectual property law, but if IKEA according to that would be stealing designs than that is not OK. Second however, engineering products in such a way that you can bring down the price by 95% while quality/niceness/longevity only suffers (let's say) 25% is a thing to marvel at. Having 75% of a €265 design stool in your house for €25 is fantastic.
