1. A respiratory mask with a sponge and fabric, configured to seal and deliver pressurized airflow to an entrance of a user's nasal and oral airways, comprising:
a partially rigid support chamber having curved sidewalls, the curved sidewalls being connected to form two annular openings, wherein the two annular openings include a circular opening configured to be away from a user's face to form a first opening configured to receive pressurized gas, and a symmetrical opening configured to be nearest to the user's face to form a second opening configured to connect with a cushioning part;
the cushioning part including an elastic body and a sponge body, the elastic body having a smooth side that, at least in part, is configured to conform to curves of the user's face and a fixed side connected to the support chamber, wherein the smooth side and the fixed side are connected by a curved connection, and the sponge body has a curved side configured to face the user's face and a connecting side opposite to the curved side configured to connect with the smooth side of the elastic body; and
a comfort layer including a first side, which is configured to at least partially contact the user's face, and a second side opposite to the first side and configured to connect with the sponge body, wherein the comfort layer is configured to be in contact with a nasal bridge of the user and, together with the cushioning part, is configured to form a sealing on the user's face, wherein the comfort layer includes an absorbent material;
wherein the comfort layer is configured to contact the user's face and has an inner edge to accommodate the user's oral and nasal airways, the inner edge of the comfort layer being smaller than or equal to an inner edge of the elastic body, and wherein a part of the inner edge of the comfort layer is smaller than or equal to an inner edge of the sponge body, and the comfort layer and the sponge body are configured to both jointly make contact with the user's face, and wherein the comfort layer and the sponge body are configured to make contact with the user's face along a connection between the inner edge of the comfort layer and the inner edge of the sponge body; and
wherein both the cushioning part and the comfort layer are both configured to deform and the comfort layer adapts with corresponding deformations in sync with the sponge body during use, wherein degrees of deformation of different parts of the cushioning part and the comfort layer vary when applying pressure of a same magnitude to different points on the cushioning part and the comfort layer in a direction perpendicular to a coronal plane, wherein the sponge body has a density at or between 10 to 200 kg/m3.
