An article (10) comprises a cushioning assembly (12) which includes a first bladder element (14) forming a first fluid chamber (16), and a second bladder element (18A) within the first bladder element and forming a second fluid chamber (20A) sealed from and within the first fluid chamber. The first bladder element comprises an inner surface having a first feature (26). The second bladder element comprises an outer surface having a second feature (32). The first feature interfits with the second feature such that a first area of the inner surface of the first bladder element is aligned with a first area of the outer surface of the second bladder element at a bonded interface. The second bladder element is exposed to the first fluid chamber away from the bonded interface. A method of manufacturing the article includes interfitting the first feature with the second feature and bonding at the bonded interface.
