OP here. It started falling apart a few years ago and we have done various things to keep it and be ok with it. So it really only held up 3+ years and now we are just taking the warranty for what it is worth. I have seen a lot of these in houses so I figured I was doing a good thing by pointing out that people could count on the warranty because sometimes stores make it a pain in the butt. To each their own!!
And for us, I have had sofas for longer than 5 years. This was a very high price for an IKEA sofa and they charged that because it came with the 10 year warranty. I dont feel guilty about this at all. If I am in the minority , so be it
