We bought this mattress in the twin size for a new daybed. We had visiting grandchildren and hated having one of them sleeping on an air bed. It worked out great! The bed is super comfy and 4 kids took turns getting to sleep in the new bed. Each one said it was the coziest bed in the house! They loved watching it expand when we unboxed it and slept on it the first night. No odors or fumes noticed. Would buy another!
