A nasal seal for a nasal mask or interface, the seal formed of a flexible material and extending between a face-contacting side and an outer side, comprising:

• a contacting surface comprising an edge that defines a nose-receiving opening and which is configured to seal about the user's nose;
• and
• an under-nose support comprising an elongate main lateral portion non-removably connected to and suspended between opposing sidewall portions of the nasal seal such that it extends laterally within a cavity of the nasal seal, wherein the under-nose support is located rearward of the nose-receiving opening and has a contact surface that is oriented to contact at least a portion of the under-nose surface of the user, wherein the under-nose support comprises one or more extension or connecting portions that extend from the main lateral portion toward and connect to the nasal seal at an upper lip region of the nasal seal.
