The problem here is, that expensive doesn't mean quality.
Buying a cheap ikea piece and replacing it in a few years might still be a better choice than overpaying for an expensive piece, that's the same quality as ikea, but with a different tag on it (both 'brand tag' and 'price tag').
Sure, if you move them around a lot or leave them in the sun they will degrade, but just using them as normal they seem to last way longer than you’d think.
Their expensive furniture is good mid-range stuff, the cheap stuff is cheap.
Such as Dwell.co.uk, coincidentally, completely unrelated afaict to OP. They make veneer-grade non-flat-pack furniture (and upholstered stuff) at a mid-high Ikea price. Made similar I think, or any number (including local showrooms) of suppliers of either drop shipped or wholesale manufactured oak+paint-grade, it seems quite common/popular. I have a couple of items from cotswoldco.com for example that have absolutely matching (but differently named) pieces available from an unrelated local independent shop, that I might otherwise assume had a small manufacturing operation too.
A photo fell off the wall and put a rather large hole in a Lack coffee table one time. We were pretty amazed that the photo frame won. It was a $25 table. I could buy many for the price of something nice.
Having small kids around, and seeing how they play, learn to use a fork, etc, I feel like we made the right choice buying cheaper. Plus what kid doesn't want to play at the table mom and dad let them sticker bomb?
The particleboard connections aren't very sturdy.
Also the assembly for ikea stuff is usually perfect.. everything aligns to the last millimeter... which again, I can't say for much more expensive furniture pieces.
It wasn't cheap. I believe the coffee table was close to $1,000.
Not long ago you could be a good brand an rely on it being good. Now most of them are just charging for the brand and not providing higher quality.
I am in the UK, I have also inherited Sri Lankan furniture from my parents and grandparents and I have lived there as well. The decline in quality is the same in both those countries. I guess it is global.
