ᐅ Multiplex Panels in KALLAX – Better than the Original Shelves?

Hello everyone,
I recently bought a KALLAX shelving unit from IKEA and am considering replacing the original shelves with plywood panels. I am mainly interested in the advantages and disadvantages compared to the original shelves in terms of stability, load capacity, and appearance.
Plywood panels are generally known to be more durable and look more premium – however, I wonder if the extra effort and cost are worthwhile and if there is anything special I should keep in mind during installation.
Has anyone here installed plywood panels in a KALLAX shelving unit? How do you assess the difference? Are the original shelves really of lower quality, or is their quality sufficient for everyday use?
I would appreciate your opinions, experiences, and possibly advice on which plywood thickness makes sense and how you fixed the panels in place.
Thanks in advance!

I would like to briefly address the topic of material properties, as it is often underestimated here:
Plywood panels offer very good dimensional stability and higher bending strength due to their layered construction, compared to MDF or particleboard, which are used in the original KALLAX shelves.
This advantage becomes especially apparent under load and with changes in humidity conditions. MDF tends to swell and can expand when exposed to moisture, whereas plywood is much more resistant due to its cross-glued layers.
This also results in a longer lifespan and fewer deformations, especially if the shelf is placed in rooms with fluctuating climate conditions, such as an office or living area.
The argument for pure stability can therefore be technically well justified.

1. Material selection: Depending on the intended use, I recommend plywood panels with a thickness between 15 and 21 mm (0.6 and 0.8 inches).
2. Cutting: Accurate measurements are essential; if you don’t have your own workshop, many hardware stores offer cutting services.
3. Edge treatment: Sand the cut edges and then seal them (with paint, oil, or wax) to prevent swelling.
4. Fastening: Small metal angle brackets provide a secure connection without damaging the wood. Pre-drilling is advisable.
5. Load testing: After installation, it is recommended to gradually add weight to the shelf and check for deflection.
6. Maintenance: Plywood panels should be periodically treated with wood care products to keep the surface in good condition.
By following these points, plywood panels offer a great improvement over the original shelves, especially when stability and long-term use are important.
