We have an IKEA Ektorp corner sofa. I really do like it for the $ but we've had 2 problems. First problem was that the back piece of wood frame broke after we'd only had it a month, but you couldn't really tell. Dh was able to fix it in about an hour but he's also Mr. Fixit. It had broken right at a knot in the wood, so it probably is not a common flaw, and just was a fluke because of that piece of wood. The first slipcover/cushion covers we had were machine washable beige twill, but the backsides to all the cushion covers were this tissue paper like material instead of the twill so after being washed 7-8 times over the course of 2 years, they started ripping so I couldn't wash them again. That said, instead of buying a new sofa recently, we just replaced the slipcover because we *do* really like it. Luckily it seems they have changed their cushion cover materials to be the same on both side like a normal sofa, so we won't have the same problem again. I think that our issues with the sofa were specifically issues that only we have had, and if I had it to do over again, I'd still buy it.
Our home is 75% IKEA and so far we really do love it minus the 2 small easily fixed issues on our sofa. Everything we have gotten has been decent quality, had nice style and been easy on our budget. I'd go for it.
