PROBLEM TO BE SOLVED: To provide a mattress that supplies air into a mattress body, can create a comfortable sleeping environment by adjusting temperature and humidity appropriate for sleeping, and also can be folded. SOLUTION: An air transferring route 16A is formed of a piping unit equipped with a main pipeline and an introducing pipeline. The main pipeline includes first pipelines 18a-18c and second pipelines 28a, 28b that are connected to the first pipelines 18a-18c through joint sections 34, 36, 38, 40. The first pipelines 18a-18c are provided with a flexible first pipe 22 between a rigid first pipe 20 provided with air outlets 26. The second pipelines 28a, 28b include a flexible second pipe 30. The air such as hot air and cold air is supplied into the main pipeline through an introducing pipeline 42 and is discharged into the mattress 10 from the air outlets 26. The mattress 10 is folded at a folding line and the piping unit is formed in a way that the first flexible pipe 22 and the second flexible pipe 30 are placed on both sides of the folding line.
