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.
