IMO Ikea furniture is not that sturdy or lasting.
I purchased a bookshelf and sadly, its shelves warped when loaded
with books. I could have overloaded them, past the permissible load
weight, but then a cupboard's not much use if it can't bear a full
row of books.
As for the "made of solid wood" claim, only some products are made
of wood, others are made from some blend of "wood" like wooden
boards hehehe. The facade looks fine, but don't look behind the
furniture!
And then there is the dreaded assembly 
I purchased a bathroom cabinet, had the renovation
workers to fix it up.. and it took 4 men to NOT assemble it
They ended up with unused parts and told me we
were short of some other parts. I junked the thing and bought a
steel rack from Sim Siang Choon.
I do like the home accessories and knick knacks though, they're fun
and well designed. e.g. photo frames, cushions and covers, rugs.
Some stuff are innovative and hard to find outside too, like an L
shaped shower rod.
