Self-inflating seats

 

— seats are called small products, the size of which is only enough for sitting. This is a good option for situations where lying places are not required — for example, going out into nature for several hours: it is more convenient to carry a small seat with you than a rather bulky rug. As for self-inflating materials, they provide softness and overall comfort, but are susceptible to damage and are expensive; the features of such materials are described in more detail in the “self-inflating mat” paragraph.
