We choose the KTT mattresses and are very happy with them. Two years ago we switched our home mattress from a temperpedic to an organic latex mattress and we loved it. Latex is a natural product and environmentally friendly, it doesn’t off gas, it is mold resistant, it is extremely durable ( some research claims it will last 20+ years), and it is dust and mite resistant, and very supportive. I have severe allergies and I did do extensive research on latex mattresses. My husband says he sleeps better in the Oliver than he does at home!
