Description

Double-layer inflatable mattress

This invention relates to the technical field of inflatable mattresses, in particular to a double-layer inflatable mattress that can connect two or more double-layer inflatable mattresses together and each double-layer inflatable mattress can adjust its softness and hardness independently.

Traditional mattresses are spring mattresses, which have interwoven spring wires or independent spring wires inside. This type of spring mattress is heavy after it is made, and it is not easy to move it to the location where consumers want to place it. In addition, this type of spring mattress cannot adjust its softness and hardness, so it must be carefully selected in advance. Nowadays, due to new materials and technological innovations, many types of inflatable mattresses have been born. Inflatable mattresses are light in weight, can be inflated for use, and can be deflated for storage, so consumers can move and use them at will. In many occasions, it is more convenient and more practical than traditional spring mattresses.

However, after the double inflatable mattress is filled with air, due to the internal airbag structure, the entire inflatable mattress can only have one softness and hardness. For two people sleeping on the same inflatable mattress, it may not meet their personal needs. For example, one person wants a harder mattress, and the other wants a softer mattress, which often causes quarrels. In addition, when two people sleep on the same double inflatable mattress, the bed surface may vibrate and float when they get in bed, get up, or turn over, disturbing the other person. Therefore, how to make the double inflatable mattress filled with air so that the two people can adjust their sleeping positions independently without interfering with each other is the first issue that this creation actively overcomes.
