What is a zero-pressure room in a hotel

A stress-free room. This is a decompression room, designed to create a deep sleep for business travelers. The zero-pressure room is an upgrade of the original room, and memory cotton with mattress and pillow is added to the original mattress. Memory cotton's resilience is very good. It can feel the body wrapped, reduce the burden on the body and reduce the pressure difference, which is close to zero, so it is called zero pressure chamber.
