ᐅ Why do some BILLY drawers not close properly?

Material deformation: wood-based materials can expand slightly or warp when exposed to moisture or temperature changes.

I agree, especially when BILLY furniture is placed in kitchens or attic rooms, temperature and humidity fluctuations can cause undesirable effects. These are particularly noticeable with particleboard, which can significantly affect drawer guides over time.

Royal4, what exactly is your setup? Is the cabinet standing on carpet, tile, or hardwood flooring? Was the floor possibly not leveled before assembly?

By the way: often removing or slightly adjusting the bump stops on the back of the drawer can improve how it closes.

That’s also a useful tip—these small bumpers often cause more problems than they solve if they are not positioned perfectly.

Thank you for the detailed responses so far. My BILLY unit stands on a laminate floor, which is fairly level. It is a combination of several BILLY units, some with and some without drawers, located in a living room with normal temperature and humidity (no use in damp areas).

The furniture is freestanding, with some distance from the walls, and I have checked with a spirit level – the cabinet is basically level, although slight tension may result from joining and screwing the different units together.

I have also checked whether the drawer fronts are perfectly aligned, and everything seems fine, with no visible warping.

Is it still possible that the plastic runners have some manufacturing tolerance? Or that slight imperfect assembly could be enough to affect the closing behavior?

Maybe the drawers were not fitted exactly parallel to the runners? However, I have already tried repeatedly removing the drawers completely and gently sliding them back in, and checked the individual rails.

My conclusion so far is that both material tolerances and assembly accuracy play a role, but none of these factors alone seem to be the cause. Does anyone have any further ideas or proven step-by-step advice?

What often helps:
Pull the drawer completely out, slightly loosen the sliding rails, realign them, and then tighten. Make sure the rails are exactly parallel.

Then reinsert the drawer and test it. Often, the rails are installed slightly misaligned.

It is quite common for dirt or fine debris to be the cause in the tracks. Simply vacuum the tracks and clean them with a dry cloth.

After that, many drawers will work smoothly again.
