My husband and I are totally satisfied with our Sleep Ez latex mattress (one, two inch layer and two, three inch layers). I purposely waited almost two years before posting a review to see how the mattress would serve us over the long haul. We give it 5 stars! My back pain has disappeared! Here is one important piece of advice to anyone trying a Sleep Ez mattress for the first time: try it for the full 90 days before you consider returning it. It took many, many weeks for our bodies to adjust to a latex mattress. At first I thought we had made a huge mistake, but our bodies just had to re-adjust - for the better! - and that took time. Now we wouldn't sleep on any other type of mattress. An added plus was the personalized, excellent customer service. Our first layered combinations were not quite right, but the folks at Sleep Ez worked with us till we found the perfect combinations.
