Firstly, I apologise if this has been posted in the wrong place but I thought it would be worth starting here!
I have a bedside table with three drawers - I'm in no way whatsoever a DIY person, so all I understand about these is that they're all connected to individual runners. Whilst two of the drawers worked without issue and would open all of the way up, my top drawer wouldn't and would only open about half way. Thinking that something might have been blocking it from opening completely, I reached my hand inside and to the back of the unit - but nothing existed in the gap that could be the cause. Then, with one hand I slowly began to pull the drawer from the very back - this worked, and the drawer eventually came all the way out. I haven't had any problems with it since.
Now - my question. If there was nothing that could have been physically causing the drawer not to open, what could this have been? As mentioned, since using some force to open the drawer it has been absolutely fine since.
Thank you for your time.
