Onceupon a time, I was recommended by a very enthusiastic pet accessories shop clerk a brand of cat litter that was made out of ground spruce. Little pellets that dissolved when they got wet.
My cat hated it. I wasn't too fond of it either, as one couldn't claim - in all honesty - that it covered the stink of cat piss.
And the stink of cat piss got worse, since she hated it so much she went to piss on my shoes instead. (I found a use for it, pour it on the puddle on the floor, let it dissolve, wait five minutes, vacuum the resulting wood dust up.. a sweep with the mop to get rid of any residue, and done.)
Anyway. My point being. Most Ikea furniture is made of the same stuff those pellets were made of: Ikea furniture stinks like cat litter.
