Just got a new 4x2 kallax to go in the playroom. Fixing it to the wall is a bit annoying because the skirting gets in the way and you have to do it on a lean, so I'd prefer not to. Plus I don't have the tools/ability to do it so will have to pay someone.
AIBU to leave it unfixed? I know that there have been some terrible stories if wardrobes/chests of drawers failing on young kids but a kallax doesn't seem as much of a risk even if full of boxes.
DC are 3 and 6, never try to climb the one in the bedroom (which is fixed).
