The electronics and frame of IKEA's electronic standing desks are whitelabled products from Rol Ergo - so that's probably why it feels premium, as it's not made by IKEA :-)
For example, I am buying some stuff specifically from IKEA, because: 1. They provide longer warranty 2. It's cheaper than the non-white label alternative (looking at you, Blum furniture fittings for example)
I need a super good reason why my next gas stove, oven and dishwasher are not from IKEA.
