I would never buy anything upholstered from IKEA, but the case goods - dressers, bookcases, etc. - are great quality for the money.
It’s just me, ok, but I think Ikea represents a ‘throw-away’ society. I’d prefer to recycle/repurpose what’s already made.
We have found the mattresses to be a great value, although we do use toppers on them to improve the experience.
We have a couple of small two-drawer chests that someone gave us when they moved - I think they’re from way back in the late 1980s.
They’re the most solid pieces of furniture I’ve ever owned, hardware and everything.
Newer pieces don’t seem quite as solid, but the newer ones we’ve had for over 10 years have held up fine.
I’m just not really into their ‘modernist, minimalist’ design concept. It seems that when we’ve bought something more traditionalist and wanted another one like it, the style was discontinued.
Re: upholstered items: our Ektorp sofa, which we got at a great discount in the ‘damaged’ section just because it had a slight tear in the back, is great. But now it’s discontinued, and you can’t buy slipcovers for it; you have to shell-out for custom ones.
