With ikea a kid can get his own setup, brand new and age appropriate.
Princess or racecar bed when they're young. bed with a desk underneath when they're getting to homework age, full sized bed when they reach 90th percentile. All with matching extras, and not too much money.
By the way, have you noticed the price and quality of furniture store furniture (when they're not "going out of business"?) A lot of it is either 10x ikea price or only 4x but still made with fiberboard underneath.

If the surface coating gets damaged or the surface gets pierced or it becomes waterlogged from spills or environmental humidity, it will quickly go bad. But they're pretty resilient to normal household use.
You get what you pay for. A LACK honeycomb table costs 7€. What can you expect at this price?
I think I was neither, as I repeated it three times and always got the same result (I was moving every couple of years, so I threw out the crooked desk top when moving and bought identical one in a new place). Eventually, I stopped getting those $40 honeycomb desk tops and got a wooden one, from IKEA as well (made not from solid wood, but from sort of glued together mosaic of small wood pieces, don't know what it's called) for around $100, which is still good as new after 8 years of usage.
Another point of view: the IKEA cardboard honeycomb material is AWESOME!
It's made from recycled material, it doesn't weigh anything, it's very strong when compared to weight and price, the surface is pretty resilient and it doesn't produce a lot of waste when it is inevitably discarded.
In today's single use culture (which needs to go away) it would be a terrible waste of resources to use nice hardwood to build cheap coffee tables that get swapped out when the fashion changes.
You can still get hardwood furniture that will last several lifetimes. It will make you feel a little lighter in the pocket, but you buy once and cry once.
