I have had this mattress in my primary bedroom since March 2010. I sleep on it daily, of course. It's starting to get lumpy and loose it's structure and it's not comfortable at all anymore. Although it was super easy to open the box and put on the bed, I would only recommend this mattress for a spare bedroom that gets infrequent use. TRUST ME, you do NOT want to make this your everyday mattress, as you will want to replace it in 2 years or less.
