- the spacer fabric which is coated with an air-impermeable layer such as PVC or PU for inflatable products, forms a flat shape when inflated.

- Such leaks within the volume element include, for example
- undesired or unintended fluidic connections are provided between the chambers, which, however, only cause an overflow of gas or air within the volume element and between the chambers, but do not lead to an escape of the gas to the outside, i.e. to the surroundings of the volume element .
- Leaks in the vicinity of the volume element can easily be repaired from the outside. It is not necessary to repair leaks within the volume element.
