Wouldn't like to think a professional would make that mistake unless the client has specific specifications or a very unusual design which they haven't done before. But as standard shelves and tables etc goes a professional should not be making that mistake.
I have yet to find a single professionally designed and made bookshelf by the likes of Ikea, Lundia, etc. that would take a full shelf full of books without sagging after a while. The only kind of bookshelf that I've found not to sag is the box-module type of bookshelves
like this.
Even expensive shelves like
Lundia ones. Sag under full book load and don't stand a chance in storage rooms. I actually managed to break a 1500mm shelf when I stacked it full of 400mm x 400mm x 10mm granite tiles (which in retrospect was maybe pushing it a bit) [tongue]
I had about 12 metres of Lundia shelves in my library and every shelf >1m long sagged after 5 years of use under hard cover books. Now I've substituted a third of them with the Boknäs modules and am happy with them, but since they are extremely expensive it will take a while to replace all. Even shortly considered to craft my own, but don't trust myself to be able to reverse engineer them well enough to stand next to the real deal [embarassed]
