Hi friends!
Recently-ish I move to my own appartment with my SO and bought a 5x5 IKEA Kallax to store all my boardgames. Picture attached.
Unfortunately some games are just too big for the Kallax, I can't store them neither vertically nor horizontally. For the longest time I've just had them just on top of the Kallax freely, but recently we (finally) got an AC unit and they would block the airflow.
Currently they're sitting on the floor but I feel sad for them :P
I considered getting a small Kallax, like a 2x2 or something and put them on top, but seems a bit overkill and I'm not sure it would be aesthetically pleasing.
While we also use Kallax for this purpose, we did not go with a 5x5, we went with individual units of 4x1 and 2x1. We attached them to the wall in rows the 4x1 at the top, some space, one 2x1, some space and another 2x1 with doors. It opens the option to store things on top of the units itself. We usually used it a bit like a display for the games we played most.
