Well they had lots of the older instructions online but not for this loft bed. It just may have been too old for even that. I really haven't had a complaint about their stuff in general and even have some of their inexpensive pine shelves. By the way their pine furniture looks awesome if you sand it, stain it, and apply a couple of coats of poly, and while it is a bit more expensive than the particle board stuff it is a lot nicer especially with a good finish applied and will last longer.
Yes I realize this is IKEA furniture, just because it is inexpensive and sold in flat pack doesn't mean it has to be complete crap. It just gets to live in the basement in rooms where hobbies are done where utility is more important that overall niceness.
