It is a pilosocereus... the whool down the sides should allow you to figure out which specific one.
It is what it is!

There is no quad-ribbed pilosocereus. On top of that plenty of pilosocerei dont pop out hairs until they are adults...some not at all

You do realize juvenile e.texensis are a lot more fuzzy than their adult counterparts, right?

I'm not sure what E. texensis has to do with this, and I'm not seeing hair on any of those pictures. Shrug!

According to my cactus reference (Anderson), there are 6 species of Pilosocereus which may have 4 ribs when mature (names available upon request), and yet more which may have 4 ribs when immature. I recommend relying on a reputable source to back up your own experience. Just because you haven't seen it doesn't mean that it doesn't exist.

No, there are no hairs in those last two pictures, no matter how you look at it (unless maybe you used a microscope). None.

You seem to be forgetting 2 important factors: how many of those species are available in mass cultivation, and how many look like these?
Define" reputable"

I am not here to argue with you about reputability, Stefan. I am trying to help the original poster.

Pilosocereus species with 4 ribs (or more):

brasiliensis, catingicola, floccosus, fulvilanatus, oligolepis, pentaedrophorus

plus I would not exclude species with more ribs, as these may be immature plants. What Thijs said earlier.

I just bought the exact same plant at IKEA. Not labeled in any useful manner, but they are way too hairy to be any kind of Cereus.

Clearly someone has mass produced these, but did not bother to send them out with a proper identification.

It is what it is!
