ᐅ KALLAX stacking for tall shelving not stable – ideas for reinforcement?

thaddeusHello everyone,
I have stacked several KALLAX shelves on top of each other to create a modern tall shelving unit in the living room. However, despite using the connecting fittings, the structure doesn’t feel stable enough. Especially at the height of about 2.10 meters (6 ft 11 in), the unit noticeably wobbles when it is lightly pushed. Since I don’t want to permanently screw the shelves together because I occasionally want to rearrange them, I am looking for ideas or proven methods to make the stacking more stable without permanently damaging or screwing the KALLAX elements.
Does anyone have tips for reinforcement, for example with additional braces, angle brackets, or adhesives? How do you ensure better stability and prevent tipping with such tall KALLAX stacks? Are there experiences with special connection techniques that are both stable and reversible? I look forward to your recommendations!
Thank you in advance!

Hello thaddeus,
your question is very precise and important, especially because KALLAX, despite its timeless design, is not originally intended for multi-level high shelving constructions. To ensure a permanently stable solution, I recommend a combination of several measures:
First: Use additional angled metal brackets that you can screw inside between the shelves. These are mounted almost invisibly inside and greatly improve the torsional rigidity. Since you don’t want permanent screws into the wood, you should use small, short screws with minimal penetration and pre-drill the spots carefully.
Second: For standing and tipping safety, it is advisable to fix the unit to the wall with thin metal brackets and screws at the back panel—if that is possible. Alternatively, adjustable leveling feet at the base can help achieve better load distribution on the floor.
Third: Apply strong construction adhesive or double-sided industrial tape to attach additional wooden reinforcements at the contact points between the individual units. This increases friction and prevents lateral sliding.
Your note about keeping the elements reversible naturally limits the options. Still, a bit of screwing on the inside surfaces that are not visible from the outside is often the best compromise. If you like, please share the exact height of the shelving and what you mainly intend to store—this could influence the choice of reinforcement.
Best regards

Hello,
for increased stability, bond the KALLAX elements together using mounting adhesive. Additionally, attach angle brackets to the back and secure the entire shelf at the bottom with a strip to prevent tipping against the wall. It is better to screw from the inside, as this holds well and is reversible.

Hello thaddeus,
I think it’s great that you’re considering stability because KALLAX shelves can indeed become more prone to tipping when stacked higher. Your challenge is to create stability without damaging the parts or permanently screwing them together – there are elegant solutions for this.
One option is to use so-called clamp connectors that apply tension between the shelves without drilling anything. These essentially push the elements apart, stabilizing them through friction. Such “clamp fasteners” are especially helpful for taller units.
Additionally, you can attach narrow wooden strips with double-sided tape in the gaps – acting as a kind of buffer or stop that prevents lateral slipping. If you’re thinking about wall mounting, simple narrow metal brackets at the rear are often sufficient and can usually be removed easily if needed.
Have you considered securing the base more firmly? Sometimes a simple rubber mat under the feet is enough to prevent the shelf from sliding.
I hope this helps you! 🙂

I’ve dealt with a similar issue myself and understand the frustration when a tall shelving unit wobbles and you’re worried it might tip over. Especially with children in the house, it makes you quickly feel uneasy.
Back then, I worked similarly to Palenar and also used magnetic strips to secure the upper elements together. This made the whole structure more stable, but the challenge is always finding the right balance between securing it and maintaining some flexibility.
Maybe gentle fixings like magnetic or Velcro strips, which can be easily removed, will help you. It doesn’t have to be a permanent screwed connection. I hope you find a good solution – it’s really stressful having to constantly check the shelf.
