Hello everyone,

I am considering using an IKEA KALLAX shelving unit as a room divider in my loft. The shelving unit is very flexible and looks stylish, but I am concerned about how stable it will be in the long term, especially when placed freestanding in the middle of the room.

My specific question:

What known stability issues exist when using KALLAX shelving units as room dividers, particularly when set up freely without wall anchoring? Are there proven methods or improvements to secure the shelving against tipping and wobbling?

For a loft living space, the unit will naturally be subject to some stress, such as leaning or placing items on it – I want it to stand as securely as possible and pose no safety risk.

Thanks for your experiences and tips!

The issue of stability with KALLAX used as a room divider is definitely relevant. These shelves are primarily designed for wall mounting or use against a wall. Without wall attachment, depending on size and load, there can be a risk of tipping.

A useful tip for stability is to secure the unit with floor fixings or non-slip mats. Additionally, a connecting strip at the back that links several modules can improve overall stability.

However, it should be noted that the carcass is made of particleboard, which means it can give way laterally under heavy loads.

As an addition: KALLAX units are generally not designed to withstand high lateral loads coming from open space. The material thickness and connection methods provide only limited stability without a wall.

The most common issues are:
- Tipping over due to uneven loading
- Warping of the modules caused by missing back panels or insufficient reinforcement

Expert recommendations include installing additional back panels, using angle brackets, or gluing multiple shelves together to increase mass and stability.

It is important not to load the shelf unevenly and to store heavy items at the bottom. Reinforce the back panel, possibly with wooden boards or metal profiles. Simply freestanding, it will be unstable.

Hello Lurineo,

I find your project very interesting! I have been working with furniture designs for flexible room dividers for years and have often used KALLAX as a base myself.

The main reason for the lack of stability lies in the particleboard material and the type of connections: the individual panels are joined with dowels and screws, which are neither particularly flexible nor torsion-resistant.

When KALLAX is used freestanding as a room divider, lateral forces (e.g., leaning, accidental bumps) directly stress the connections – this is exactly what poses safety risks.

My recommendations:

1. Module connection: If possible, connect several KALLAX units using corner brackets or simple wooden dowels. This increases the mass resting on the floor and drastically reduces the risk of tipping.

2. Reinforcement of the back panel: Standard KALLAX has thin back panels made of fiberboard, which easily flexes. Replacing the original back with a 6-8 mm (0.2-0.3 inch) plywood panel greatly improves stability.

3. Floor level correction: Small unevenness, especially on parquet or hardwood floors, can promote wobbling. Rubber feet or anti-slip pads can help.

4. Additional securing: A subtle attachment to the ceiling using wire cables, if possible, was a very secure solution in my case and is something I would recommend here if the ceiling allows it.

My question to you: How large is your KALLAX unit? Number of compartments? And will it be used only as a room divider or also heavily for storage?

Thank you for the detailed answer. The shelf is a 4x4 unit, so it has 16 compartments. It is intended both as a separation between the living and work areas and as storage for books, plants, and decorations. So the load will be moderate to heavy, not just light.

The idea of reinforcing the back panel sounds good, but what is the best way to attach the plywood sheet? The original screws through the back panel don’t hold very securely.
