Nice unit,  don’t be put off by the box when it arrives thinking you’ve not got the right 2.2M high unit, the left and right sides consist of two pieces joined together,. It’s a sturdy unit for something as high as this, very little flex. Definitely secure it to wall, it’ll take forever to alphabetise them CDs again if it topples ;). Only gripe, less sticky glue please on the stickers that identify the shelves, 22 of them needing soapy wipe to clean off the glue gunk.
