hi friends!

so i'm looking into purchasing the chest of 3 MALM drawer (https://www.ikea.com/au/en/p/malm-chest-of-3-drawers-white-90354643/) but am wanting to add an extra unit on top, preferably some sort of shelfing or cube storage. initially, i was thinking of the KALLAX (https://www.ikea.com/au/en/p/kallax-shelving-unit-white-70351886/) but i have seen another post in here about it, people were advising against it as the kallax is quite heavy and may not be the easy to mount to the wall. to be fair, that was one of the largest kallax whereas as mine is the smallest one (4 cube). any thoughts? or if anyone could recommend something else, preferably the same or similar width of the malm dresser? (also please note, I am in australia. so i don't have access to most international stores.)

thanks so much in advance!
