In July I bought a new bedroom set along with a mattress and box spring. Loved the furniture but could not get a full nights sleep on that mattress. Everyday I would get up with muscles aches and shoulder, and back pain. Both of my sons have a Zenus mattress and urged me to buy one. After visiting with my youngest son and slept on the Zenus mattress he bought for me in his guest room it was the best sleep I had had. I ordered one for me and when my sons came for Thanksgiving they set it up for me. I have only had two nights on it but I am sleeping better than ever! I had read reviews that some people experienced a chemical smell with their mattress but I did not. This is the best mattress ever and recommend it to everyone.
