Under the Dharmaguptaka, in the first heading: regarding the note stating "fitted and lined": The Ceremonial Standard states: "Whether large or small, both [kinds of] mattresses refer to having felt inside as the core, padded outside with cotton floss, and covered over with cloth or silk. If it is felt and cloth on only one side, it is reckoned as light."
