TECHNICAL FIELD

This application relates to outdoor camping equipment, and more particularly to an inflatable mattress with a detachably-fastened quilt.

BACKGROUND

Current outdoor camping sleep solutions typically treat inflatable mattresses and quilt bodies (or sleeping bags) as separate, independent items. This separated design introduces several critical drawbacks in practical use.

Firstly, the quilt body tends to slip, curl, or even fall off the smooth surface of the inflatable mattress during user movement. As a result, the user’s body becomes exposed to cold air, which significantly compromises thermal retention and sleep quality. Secondly, the traditional rectangular quilt body provides inadequate coverage around the shoulder and neck area. This design readily forms gaps that allow cold drafts to enter and accelerate heat loss. Furthermore, achieving sufficient head-level wind protection and warmth often requires additional equipment. Users must carry and set up separate shelters such as tarps, or rely on bulky sleeping bags. These supplementary measures are cumbersome to deploy and integrate poorly with the core sleep system.

Additionally, conventional inflatable mattresses, sleeping bags, and quilts are needed to be independently stored and packed, resulting in large space occupation, poor portability and time-consuming arrangement process.
