Hello,
push the white "nipple" on the left and right of the rail from below with a sharp object. Then you can pull out the slider.
It's not hard at all if you know how :)
best regards
Tell me, how do you come up with that? Of course, fiddling around with a sharp object there? Ideally, so that the whole drawer gets bent and scratched and if there’s ever a warranty issue, you find yourself unable to explain it. Great!
Reach under the drawer front at the front and pull upwards with a good jerk. You need strength for that. But it has to be that way, because the drawer is supposed to take real weight. If you don’t trust yourself enough, go to your nearest Ikea and have them show you. Most employees will encourage you to try it yourself. ;)
