As a Board Certified Sleep Specialist, I know the importance of a good night`s sleep. Personally having scoliosis, I`ve always found it difficult to achieve a high level of comfort throughout the night with most mattresses. However, the Zotto mattress is different, my back discomfort while sleeping is no longer an issue. I can honestly say that I`m not only pleased with the quality and comfort of this innovative mattress, but more importantly I`m surprisingly pleased with my personal results and decrease in lower back pain. I recommend the Zotto mattress to my sleep patients.
