2015 B250 armrest/storage. The lid of this is a slider (don't know why it was made like this) but it slides forward with the slightest of touch. If there is a drink in the closest cup holder, it will now be spilled if this arm rest moves. I can't figure out how to lock it in place. Haven't talked to MB dealer about this yet. Has anybody got any ideas?

Mine stays in place when it's pushed towards the back seat. When only using 1 cup holder I slide it to the front and it stays in place as well. But that being said, took me a while to get used to it.

Sounds like you may want to take it into the dealer to have a look. It should not move with the "slightest" of touch, so sounds like there's something that needs to be corrected since it does take a bit of a push to move the middle arm rest.

Let us know the outcome ...
