Hello everyone, I recently connected several KALLAX units to create a larger shelving system. Unfortunately, I noticed that the connected side panels feel a bit wobbly after assembly. A single unit is stable, but once shelves are combined, the side panels sometimes give way, which not only causes a “wobbly” feeling but also makes me concerned about potential long-term damage to the system.
I’ve read that some people use additional brackets or screws, and sometimes it’s recommended to reinforce the back panels or secure the entire structure to the wall.
I’m particularly interested in options to make the side panels more stable in a KALLAX combination without significantly altering the appearance or completely disassembling the unit. What techniques or tools have you used? Are there specific screws, brackets, or other materials that are especially effective? And is it advisable to add more back panels or extra stabilizers?
I would appreciate any tips that can help solve the problem of wobbly side panels in combined KALLAX shelves for the long term!

For free-standing KALLAX units, you can also consider using so-called furniture connectorsI am skeptical about this: Many third-party furniture connectors are either not precisely matched to the panel material of KALLAX or result in irreparable drill holes.
Furthermore, I believe the manufacturer accounts for some wobbling—the density and thickness of the particleboard balance stability with limited flexibility.
I would prefer a combination of a reinforced back panel and smaller brackets that do not put too much stress on the sides.
Has anyone had long-term experience with how these connections hold up after several years of normal use? Are there measurable deformations?
Hello everyone,
I can only confirm the points made so far and would like to address a few basic aspects that are often overlooked:
1. Shelf material: KALLAX units are made from thin particleboard (MDF), which behaves differently under stress in joints compared to solid wood. This means the joint needs to be flexible enough to absorb tension but firm enough to minimize movement.
2. Additional back panels significantly increase bending stiffness, but even thin strips around the edges (e.g., wooden edge trims) can improve stability.
3. For the connection, I recommend using dowel pins or so-called connector dowels, which are invisible in the wood and provide a strong bond.
4. Finally: If the shelf wobbles, it’s worth checking the floor. Often, wobbling is caused by a slightly uneven surface.
I think it’s good that you don’t want to compromise the appearance, but there are discreet solutions that hold very well and remain visually neutral.
Good luck!

Wobbling often occurs due to a slightly uneven surface. That's correct. Be sure to check and, if necessary, place small furniture shims underneath. This often provides an immediate fix.
