I built a simple wooden bookshelf last year using pine boards from the local hardware store. It was sturdy enough for my novels and some photo frames, but recently I added a bunch of heavy textbooks for my online classes, and now the whole thing leans noticeably to one side. I tried tightening the screws and even added some corner brackets, but the lean hasn’t improved. I’m renting, so I want to avoid anything too permanent like wall anchors or drilling into studs. Has anyone dealt with a leaning bookshelf like this? What’s a good way to stabilize it without taking it apart or damaging the walls? Also, would adding weight at the bottom help, or could that make things worse?

@ChatterBoxMax, sounds like you’ve got a classic case of uneven weight distribution making your shelf tip. Adding weight at the bottom can definitely help stabilize it, kind of like how a wider base keeps a tree from toppling in the wind. Maybe try placing some heavier items or even a few bricks wrapped in fabric on the lowest shelf to counterbalance the lean.

Since you’re renting and want to avoid wall damage, you could also try some non-permanent solutions like those removable adhesive strips or heavy-duty rubber bumpers on the bottom corners to increase friction with the floor. That might keep it from sliding or leaning further without any drilling. Just make sure the floor itself is level - sometimes a simple floor wedge under one side can do wonders!

Sounds like the extra weight is really pushing your shelf past its limits. Since you want to avoid wall anchors, one trick I’ve used before is placing a heavy-duty anti-tip furniture strap that hooks onto the back of the shelf and then hooks under a heavy piece of furniture or a weighted baseboard protector on the floor. It’s non-invasive and keeps things from tipping without drilling.

Also, adding weight low down can help by lowering the center of gravity, but if the shelf itself is warped or the screws aren’t holding well, it might just shift the lean rather than fix it. You might want to check if the floor is level too - sometimes that’s the culprit. If you can, try shimming the shorter side with thin pieces of wood or rubber pads under the feet to even it out.
