Well precisely - shelves feels especially like a solved problem where basically the cheapest tat you can buy (IKEA) is totally fine and solid and long lasting. Need something more hardcore? Then you're probably not in the "shelves on my living room" context, but probably need something more suited for an industrial setting.

It was a genuine question about what makes these any better (...or not). Like do they have some amazing non-obvious feature? Something that no other shelf has? Something that IKEA shelves fail to do?

Of course it could be a performative thing (as I was suggesting) in the same way that someone pays $150 for a t-shirt because it has a logo on it and they want people to know. There is a sucker born every minute as they say.

But those don't even look good. Like, I thought it was some IKEA series that I didn't knew, just raw aluminum profiles + some uninteresting shelving
