Here’s the quote that convinced me to get my sofa from IKEA:
A good sofa is one you can’t resist. It beckons when you pass, inviting you to actually enjoy your own living room between dinner parties… Don’t buy a sofa with your in-laws and guests in mind. Buy it for you. See if it seduces–does it tempt you to stretch out lenghwise with a magazine.
