We’ve got IKEA cabinets in our kitchen and all of our bathrooms. They’ve only been in use for a year, but then… it’s been a year, and they’re still in perfect condition. No nicks or scratches, no wobbliness, no worries at all.
We have the white Adel cabinets in our kitchen. They have some kind of smooth plastic or powder coating. As far as I can tell, they’re impervious to damage… and they’re really easy to wipe clean. All the hinges run smooth as silk. All the doors and drawers come with levelers, so we got the kitchen looking picture-perfect.
We have the brown-black Hemnes cabinets and Pax wardrobes in the master bathroom. Now these, you do need to be careful of. Our cabinets themselves are just fine (and oh, those dreamy wardrobes…) but the remodelers scratched the matching toilet seat, which leads me to believe that the rest of the stuff could be scratched, not in the normal adult course of things, but if you have toddlers playing around or you need to drag a ladder in and out of the room.
So for durability I recommend a solid color rather than a faux-wood finish. Also, if you buy any pieces that are shrink-wrapped rather than boxed, inspect them VERY carefully to make sure the wrap is intact and they still have all their hinges and fasteners. We initially bought a couple of hanging rods that had had their fasteners removed or lost.
