I was thinking or buying a Tempur mattress but was put off by how expensive it was. Then my husband read good reviews of Ergoflex and we decided to give it a try because it was one fifth the price of a Tempur mattress. We are very pleased with the Ergoflex as there is absolutely no "roll together" and no partner disturbance. I am a side sleeper and I am able to sleep all night on my side without having to toss and turn because of pressure on my hips and shoulders. We paid about $1200 for our king size mattress on special and we wished we had bought the Ergoflex instead of our King Koil mattress that cost us $3000 and we had "roll together" within 2 weeks of buying it. The 10 year warranty on the King Koil was worthless as we had to pay $60 to have the mattress looked at, only to be told that some degree of sagging was within industry standard and that their own testing did not reveal any "roll together". We ended up giving away our $3000 King Koil mattress after 3 years of poor sleep and backache. Glad we found the Ergoflex. It is worth every cent and more !! Within 2 weeks of sleeping on the Ergoflex, my backache that plagued me eversince we got the King Koil disappeared.

Approximate cost: $1200
