Comfortable, but still gives off awful fumes 2 months later. I am constantly running a fan in the room and relaundering bedding trying to get rid of the chemical smell. I have a zippered protector and thick mattress pad. My daughter has headaches and wakes with a stuffy nose and raw throat (unless she sleeps in my room on the floor which is happening way too often with this new mattress). Not happy. We bought a different brand for our son.  Zero issues with his bed.
