We also have moved ikea couches multiple times and they are fine. It is easy to get replacement cushions when the kids spill stuff on the couches and when the wife decides she wants to get rid of it, it doesnt bother me. We have had our ikea for 6-7 years now, but before that we had very expensive louis shanks furniture and when her tastes changed to modern we got rid of it all.
She wants to change the dining room furniture, but at 1K per chair with 12 chairs that is not happening.
