ᐅ Kallax Shelving and Children's Toys – Experiences with Durability?

Hello everyone,

I have a specific question that has been on my mind lately: How durable are the IKEA Kallax shelves when used as storage for children's toys? I am particularly interested in how they hold up in everyday use with toys of varying weights that are often stacked improperly, whether the shelves sag or even break, and what to watch out for when loading them.

Does anyone have long-term experience or even technical knowledge about the maximum load capacity of the individual compartments? Also, what about safety concerns for children who like to pull themselves up on or climb the shelves?

Thanks in advance for your insights!

Hi Leburkhard,

a little reassurance upfront: The Kallax series is actually quite sturdy, even if it gets daily "wear and tear" from children’s toys. The shelves can handle quite a bit as long as they aren’t overloaded with very heavy items – but it easily copes with a bit of “toy chaos” like books, small building blocks, or stuffed animals.

what to definitely keep in mind when loading it

That’s the key point: Even weight distribution is important. I recall it’s recommended to store heavier items toward the bottom to prevent tipping, and not to exceed about 13–15 kg (29–33 lbs) per shelf. But of course, if kids regularly throw things on it for fun, that doesn’t help things 😉

My kids also like to climb on it, and I find the stability surprisingly good. Still, anchoring it to the wall is essential, otherwise it could become dangerous.

All in all – for the price, it’s really a solid companion for a children’s room 🙂

Hello Leburkhard,

to answer your question thoroughly, here is a somewhat technical overview: The Kallax shelf is made of medium-density fiberboard (MDF) with a foil finish. Although it is not solid wood, the panel thickness of about 16 mm (0.6 inches) makes it fairly sturdy. According to IKEA's specifications, the maximum load capacity per shelf board is approximately 13 to 15 kg (29 to 33 lbs). It is important to adhere to these limits, as exceeding them can compromise the shelf’s stability and cause the boards to bend.

In practice, it depends on how the weight is distributed. Localized overloading, especially with heavy toys placed in single spots, increases the risk of warping or breakage. The back panel also contributes to stability when properly secured.

Regarding safety: The shelf is not designed for climbing. Children should only use it for playing or tidying up, not as a climbing aid. To improve tipping resistance, wall mounting is recommended—even when the shelf is fully loaded.

If you plan to store particularly heavy or large toys, consider additional dividers or insert boxes to better distribute the weight. I hope this helps! If you need more information on installation or user practices, feel free to ask.

Well, I generally find these shelves to be quite overrated when used simply as "toy storage" for children. Sure, they might support the weight, but honestly: kids are constantly climbing on them, pulling themselves up, and in my experience, the shelves would have warped or developed cracks by now.

I agree that this is technically correct, but it doesn’t take into account the “everyday play” situation. The MDF can tolerate some stress, but I bet a Kallax wouldn’t last long in a real kids’ room, based on my experience.

I would recommend shelves made of solid wood or metal frames for greater durability – a bit more expensive, but in my opinion more sustainable, especially with active children. :-)

I have the Kallax in the children's room. Important: secure it to the wall and store heavy items as low as possible. Otherwise, no issues. The shelves have held up well for me for two years – even with lots of Lego and books.

Good morning,

I would like to add to the discussion because the topic of "load capacity and safety of shelves in a child’s room" is really important and should not be underestimated.

In addition to observing the maximum load limits, it is also important to consider the arrangement of the shelf:

- Place the heaviest toys on the bottom to reduce the risk of tipping.

- Make sure to securely fasten the shelf to the wall; this is especially crucial for Kallax units, as their wide open structure can easily tip over otherwise.

- Also ensure there are no sharp edges on the finish to prevent injuries to children.

It’s also advisable to regularly check that screws and connections are still tight, as they can loosen slightly over time due to occasional moving or assembling.

I hope this helps! If anyone has additional tips for safe handling, please feel free to share.
