I spent MONTHS, nearly a year actually, researching mattresses, beginning with quality, price and reviews. I am frugal and wanted to get the most for my money. I decided on this mattress because I have had nothing but positive experiences with O.co in the past. So ... it is cold here in Michigan right now and the mattress arrived and it too was cold ... so it took a few hours to expand but the second night I slept on it. I slept okay but not great. The third night I invited my husband to join me ... My hubby and I have not slept together in over a year because he hated our mattress and couldn't get any sleep on it. He almost didn't wake to his alarm because he was sleeping so good. And now it has been over 2 weeks and I cannot believe how great I feel and sleep is awesome. The bed feels soft yet supports so perfectly. I realize each opinion is unique with each person, but my opinion is why spend huge money when you can be this happy with a bed at this price. I can buy 4 or 5 of these mattresses for the price of some of the "Name Brand" and have a new bed every few years ... although I don't think I will want or need one. My final word is LOVE ... I love this mattress!!! And so does my hubby!!
