I gave it a try but it just didn't work for me. The Flobed was too soft, even when I tried 3 super firm cores. It started out good but then the back aches came. It was a good test and the Flobed folks were very nice. It's just not the right bed for me. I contacted Flobed last week. They said I can return with no problems. I'm just awaiting their e-mail with instructions. For now, it is back to the memory foam bed. I sleep close to the sides because that is where it is the most firm. It seems like I've sort of worn out the rest of the bed over the past 2 1/2 years or so as it sinks too much and offers no back support. Thanks to everyone for all their wonderful support and comments. It seems like Flobeds is a good company and a good opiton for some - just not for me. I am very thankful I can return the bed and get most of my money back.
