I just discovered this link tonight. I was on one of your links that discussed sofa sleepers, but I can't find it now. So here I am. I hope those with experience will find this message.I am getting ready to buy a kelssner sofa sleeper.I am on a tight budget, the price including the upgraded 6 inch posturepedic mattress is $699. It will only get occasional use as a sleeper, and moderate use as a sofa. I need some quick advice
