I have a little Ikea Lack table that holds my printer. I paid less than $10 for the table and I don't even think it's wood (cardboard maybe?). It's getting close to 20 years old and is in great shape.
Of course there's an aesthetic difference.
One of the genius things Ikea did was have little staged rooms in their store. They do a great job of these and lots of them look like rooms I’d want to spend time in. You see how that various pieces can be combined into something very inviting.
Furniture that lasts forever is an anti-feature for some. They want to change their furnishings about as often as cheap furniture lasts anyway. I mostly buy quality furniture, but sometimes I don't know what I really want and Ikea and Wayfair are great for that. Cheap enough to donate after I decide what quality piece I really want.
And you're reversing cause and effect. Do the consumers prefer a disposable lifestyle or is that a cope?
