I can't open the link, but think i've found the one you mean, i have the 3 shelf version so can't help with measurements.... but....
Its awful
(sorry) if you so much as nudge it, it practically falls over, the wardrobe in the same style i had to refix together twice, the shelves because they are slatted are uneven and make it impossible to stand anything straight on them.
Ours was put together by my father in law, who is a joiner by trade, so i know we didn't do it wrong - in total we have 2 3 shelf units, 2 wardrobes, and 2 bedside cabinets, and so far the bedside cabinets are the only items that haven't needed fixing.
They are great as occasional use storage (one of ours now has stuff we hardly use in it) and if tightened monthly, its really useful, but i wouldn't trust ham cages on it - sorry
