Hello everyone, I have a Billy bookshelf with doors that, after a while, tend to tilt on their own, so they no longer close straight but hang slightly crooked. Does anyone have experience with reinforcing or stabilizing the doors on this type of shelf to keep them straight for a long time? I suspect it has to do with the door hinge mechanism or the material, but I would prefer not to just buy new hinges without a well-founded solution. Are there any affordable tips or modifications for a lasting result?

Doors may sag because the hinges are not installed precisely or because the cabinet itself is not perfectly level.This assessment is very accurate. The cabinet must be perfectly level to prevent the doors from sagging due to their own weight. A spirit level can easily be used to check this, and if necessary, small shims or wedges can be added to correct it. Only when the basic structure is correct do reinforcements truly make sense.
I would like to add that sometimes the screws in the hinges can be replaced with longer or self-locking screws to ensure a firmer fit. Additionally, a small strip of wood can be glued into the frame as reinforcement for the screws. This reduces the risk of the door sagging due to loose fittings. This is especially helpful for older Billy-style shelves that have been frequently moved.
Thanks for your suggestions so far! I have actually already checked, and the shelf wobbles slightly on one side – I will level it out. Additionally, I was a bit concerned that the veneer or thin material of the door itself might be too weak. Would it make sense to apply a thinner panel or MDF on the inside of the veneer to address the stability issue? I am mainly interested in a lasting solution without having to buy completely new doors.
An additional MDF panel on the interior side can reinforce the door, provided the hinges can support the extra weight. This is a practical solution but requires careful installation, as otherwise the doors may no longer fit properly or may shift. Especially the hinge attachment points should remain sufficiently strong.

Does anyone have specific experience on how much thinner the MDF should ideally be for bonding? I’m thinking around 4mm (0.16 inches), which seems like a good compromise between weight and stability.
