I would happily rate 5 starts. I brought this for my mother. She used to wake up early morning daily by 5 and she used to complain for back pain with previous mattress but with sleepy cat mattress now she sleep till 7 or 8 o clock in the morning. I am happy that she is happy. Worth every penny spent on it. Their service support after buying the product is excellent which is must for any product. They follow up regularly right from beginning to check whether you are buying correct size mattresse for the Cot and also keenly observe if the customer is happy with the product.
