ᐅ Is it possible to assemble a KALLAX alone, or is it better to do it with two people?

Hello everyone,

I am planning to get a KALLAX shelving unit from IKEA and would like to assemble it myself. However, I am unsure whether assembling a KALLAX unit alone is generally manageable or if it is better and safer to have two people do the assembly.

I am especially interested in how the workload is distributed, whether there are stability benefits when assembling with a partner, and if there are particular assembly steps that are difficult to handle alone.

Has anyone had experience assembling the KALLAX shelving unit, specifically regarding solo assembly versus working together?

Thank you in advance for your insights!

I have assembled several KALLAX shelves on my own. It is possible if you allow enough time and work systematically. However, it is easier with two people because the parts can be held more securely.

The KALLAX assembly is basically designed so that it can be completed by an individual. The components are not especially heavy, but during the final assembly—particularly when installing the back panel and aligning the modules—having a second person significantly eases handling.

Additionally, assistance reduces the risk of misalignment and allows for better stabilization while securing the wall mounts.

In my experience, assembling with two people is safer and faster, but it is not strictly necessary.

Assembling KALLAX alone is possible, but not ideal. It is faster and less stressful with two people.

I had a similar dilemma: if you want to start on your own, it can be frustrating to have to lift a board and screw it in place at the same time.

That really resonates with me. But if you are well organized and patient, you can manage on your own. At some point, I asked someone to help, and that made the assembly much more pleasant.

Regarding the topic "Is it possible to assemble KALLAX alone or better with two people?" I would like to add some technical details:

The individual KALLAX components are mostly made of particleboard with a melamine coating, which makes them relatively lightweight but quite large in surface area. This means that when handled by one person, there is a risk that the panels might tilt or be misaligned when positioning smaller parts (e.g., back panels or connecting pieces).

If assembling alone, you should definitely:
- Have enough space to spread out
- Choose a working height at table level
- Compensate well for tolerances when aligning the back panel (e.g., with small wedges or similar)

With two people, the parts can be accurately held in place while the other screws them together, which improves quality and reduces the risk of consequential damage.

How exactly do you plan to assemble it? Do you want to build a single KALLAX unit or connect multiple modules? This significantly affects the required effort.
