ᐅ KALLAX as a TV stand with insufficient load capacity – how to reinforce it?

Hello everyone,

I am planning to use an IKEA KALLAX shelving unit as a TV stand. Overall, I like the design and the modular construction, but according to the datasheet, the load capacity is about 13 kg per shelf (29 pounds). However, my TV weighs significantly more, around 22 kg (48 pounds), plus additional devices like a receiver and a soundbar. Therefore, I am concerned that the KALLAX unit may not be stable and strong enough for this load.

My specific question is: How can the KALLAX shelving unit be reinforced or modified effectively so that it can safely support the higher weight of the TV and accessories over the long term? I am looking for simple and sturdy reinforcement options, ideally with materials available at a hardware store. Any experiences from others who have solved this issue would also be greatly appreciated!

Thank you in advance for your tips and advice.

The KALLAX shelf is not sufficiently stable and load-bearing as is.

The issue with KALLAX shelves is well known: the middle shelves are not designed to support high point loads.

My recommendation:

1. Install additional cross braces made of sturdy wood or aluminum to prevent sagging.
2. Reinforce the top surface with a plywood panel that rests on the full height of the shelf sides.
3. Optionally use metal brackets at the inner corners to improve the connection between the side panels and shelves.

This significantly increases the load capacity and distributes the weight more evenly. It is important with any reinforcement to ensure careful installation to avoid weak points.

Thank you for the tip, that reassures me a bit because I also have a KALLAX used as a TV stand and wasn’t sure if the shelf would soon suffer under the weight.

It’s frustrating when you choose a simple piece of furniture and then have to figure out how to improve its stability. I appreciate hearing about others’ experiences—it shows this issue isn’t uncommon. Hopefully, we’ll find more solutions here—safety comes first, as no one wants their TV to fall eventually.

How can you effectively reinforce or modify the KALLAX shelf so that it can safely support a higher load permanently?

Hey, I upgraded my KALLAX like this: I simply placed a thin OSB board on the shelf compartments, which I trimmed a bit beforehand – it’s really sturdy and has a cool “lofi-industrial” look.

I also screwed small metal brackets into the corners to provide extra support to the side panels.

Of course, it’s not the most elegant solution, but it’s an affordable and solid way to securely hold a TV.

Good luck, and don’t stress – a KALLAX is pretty robust if you give it a little help.

Small DIY Guide to Reinforcing the KALLAX as a TV Stand:

1. Gather materials:
- Plywood or OSB board (18 mm (0.7 inches) thickness recommended)
- Metal brackets (at least 4 pieces)
- Screws, wood glue

2. Preparation:
- Cut the board to fit the inside of the side panels
- Optionally secure the shelf additionally with glue

3. Installation:
- Place the plywood between the side panels and fix it on both sides
- Attach metal brackets at the top and bottom corners for better load distribution

4. Notes:
- Be careful not to place screws too close to the edges to avoid splitting the material
- Avoid concentrating the load on a single point; distribute devices as evenly as possible

This method provides a long-term stability improvement without significantly changing the design.

In my opinion, this thickness is optimal. Thinner material does not provide enough rigidity, and thicker would be oversized and heavy.

Another tip: If the shelf is placed on a somewhat smooth floor, it is advisable to use anti-slip pads underneath to prevent tipping under heavy load.

Although IKEA often scores with clever design, you should always check whether additional reinforcement is advisable for higher loads. When in doubt, it is better to invest a little extra effort than to risk material failure later.
