In furniture, you definitely get what you pay for...or not. I've found anything <$300 is going to be nothing but fake materials like manufactured woods (if not even just veneer covered cardboard) and horrible cushion/fabric.
Anything decent doesn't really start until ~$1k, and anything in the $3k range you mentioned starts to become heirloom quality. As with anything, these are YMMV, but serves as a fast basis for my experience
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.
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.
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.
You have to know enough to know who is actually building the good stuff, and who is building good-looking marketing.
You can see that from the number of "small brand" insta-entrepreneurs. People will readily shell $80 for the latest trendy item they saw in a sponsored insta-ad, believing they're buying a branded product. In reality, it's the same $20-$30 item sold on TEMU, with a brand name slapped on it.
