Which cabinets would you recommend for the cellar?

You can display the dimensions at any time. And honestly, I would leave out corner modules. Just upload the floor plan of the room.

We were at Ikea yesterday.

We decided on the Ikea Bror there. They are super stable and also modularly buildable (yes, not as flexible as the Ivar) but Ivar was already shakier than Bror and can withstand less (according to Ikea lower load capacity).

The connection on the Bror is only a plug connection and not a clamp connection; that should also be changeable without problems.

We will align the shelves with the bottom to the Ikea boxes so that they fit perfectly in the different sizes and then you don’t change the shelves anymore.

I just don’t know where you found the official load capacity at Ikea?

I can’t find it, regardless if for IVAR or BROR.

I just don't know where you found the official load capacity at Ikea? I can't find it, whether for IVAR or BROR

On the website, open a shelf board, then under the menu item "Dimensions" it is listed.

Oh, I see :D

I always looked at the complete shelf and not at the individual shelf :D

somehow stupid that it’s not stated on the complete shelf

Bror has a max load of 95 KG and IVAR 35 KG

Thus, Bror holds about 3 times as much as IVAR

Well, the Brorboden is also a good 30% deeper than the Ikea 30 cm shelf you used as a comparison ;)

Here again a fair comparison

Bror = 84 wide and 54 deep = 130 Kg load capacity

Ivar = 83 wide and 50 deep = 45 Kg load capacity

Bror is about 3x more load-bearing
