Those desks do have hydraulics: https://www.ikea.com/au/en/p/bekant-desk-sit-stand-white-s09...

Ikea's goods usually come in different price ranges with the most expensive often not being 'cheap' but 'cheap given the quality'. That being said, often their cheapest stuff is the best value for money because it's so cheap that it lasting more than a year would be a miracle (but they usually do!).

Yeah, ikea standing desk prices are crazy. There are plenty of comparable products on Amazon for a lot less money. I kept looking at them in the store thinking that there must be something that could warrant the price, but I just can't see it.
