6. To hang it I found a Youtube video with instructions for hanging a Kallax and followed the instructions. I definitely recommend to secure ONLY to wall studs. I had to drill and move one of the brackets to align to the studs at 16 inches apart and to have 2x the number of brackets. I didn’t use the lower brackets, because I think it’s sturdy enough. But use your own judgement.
7. The carpet or rug I cut to size and used Velcro to affix to the inside of the KALLAX.
