ᐅ KALLAX used as a room divider is loosely assembled – how to support it?

Hello everyone,

I am planning to use my KALLAX shelf from IKEA as a room divider in my living room. The shelf is only loosely assembled, without screws or fixed connections between the individual units. Now my question is: How can I best stabilize or support the KALLAX so that it stands securely over time and does not suddenly tip over or come apart? Are there proven methods or additional parts that can be used? On the one hand, I don’t want to make any holes in the wall, but on the other hand, the shelf should be safe and not tip when removing individual boxes. I look forward to concrete suggestions on how to solve this problem.

Hello Janre,

to keep a loosely assembled KALLAX shelving unit stable and secure when used as a room divider, I recommend using stabilizing elements such as metal brackets or custom-made wooden strips that support the unit at the floor and ceiling. A clamp or tension system between the top of the shelf and the ceiling is advisable to prevent wobbling.

Alternatively, for IKEA shelves, there are connection fittings available that mechanically link multiple KALLAX units together, providing greater stability. These accessories can be securely screwed in without significantly affecting the appearance.

Regarding removing the boxes, it is also useful to attach non-slip floor profiles or felt pads under the shelving unit to prevent it from sliding on smooth floors. This can also provide slight anchoring to the floor without mounting it to the wall.

This approach addresses all stability issues without damaging the wall.

A question regarding this: Are such connecting fittings really necessary, or can the shelf simply be stabilized by its weight on the floor? I’m interested to know whether the risk of tipping is truly significant enough to require mechanical connections.

After all, Janre intends to use the shelf as a room divider – which usually means there are no walls nearby. My assumption is that without these fittings, the shelf could quickly become unstable, especially when pulling boxes out. So I believe additional support from above or the side is essential.

Furthermore, the factor of material fatigue in loose plug-in connections should not be underestimated, especially under long-term load.

I would either use tension rods between floor and ceiling or connect the individual modules with clamp fittings. You can also secure it to the floor with screws if you don’t want to attach it to the wall.

Thank you for the important question. So far, I have only used individual modules and simply connected them loosely. My room divider will be about 1.80 m (6 feet) high and will carry some weight from boxes and decorations.

The problem is that the modules shift slightly against each other under load due to the loose plug-in system, which causes wobbling. Because the KALLAX alone has relatively little weight without being fixed to the floor, the structure is prone to tipping.

For me, it is important that I can move the shelf at any time while still ensuring safety during use. This seems to be a conflict between flexibility and stability.

Are there any smaller, simple solutions, such as clamp fixtures that can be added afterward without permanently screwing them in?

Janre,

if you prefer not to fix the unit to the wall, a stabilizing ceiling-to-floor tension system is recommended—such as adjustable poles with rubber pads. These securely press the shelving unit in place without damaging it and can be removed without leaving any marks.

This can be reduced by using special connectors or adhesive at the joints. It is important to use a removable adhesive in case you want to take the shelving unit apart later.

I also recommend attaching felt pads under the feet to prevent slipping on smooth floors.

This combination provides a good balance between stability and flexibility—and avoids making holes in walls.
