Recent Customer Testimonial - "My husband and I were looking for a mattress made completely of natural, non-toxic materials that would inhibit as much motion transfer as possible. On a bit of a leap of faith, we purchased a king-sized extra-firm rubber mattress and a split slat foundation for it. We loved it immediately. A year later, we still love it. The only downside seems to be that hotel stays are no longer as comfortable as they used to be, by comparison!"
