Given IKEA essentially produce throwaway furniture by design, I don't think they've got much of a leg to stand on when it comes to environmental responsibility.
Just buying more stuff is literally how they have historically marketed themselves.
The price point might make people buy more that's true but calling it throwaway is hardly fair, still have a fair amount of 20 year old ikea stuff around the house and they're pretty extreme about quality assurance.
Indeed, IKEA stuff is really well built, solid, and lasts for years. I’ve had so many bad pieces of furniture from other manufacturers, IKEA just lasts, year after year, move after move
The “IKEA is crap” thing seems to be an American trope.
