English because my Czech is not very good: This self-inflating pad is a big improvement over the air mattress that I had. I was skeptical before buying it but I can say that it is extremely comfortable for sleeping.and inflates quickly. It offers excellent lower back support while sleeping, too. Deflating and storing is not so easy and needs two people for that process. Other than comfort, the intake and exhaust valves are unique and make inflating much easier. If someone is looking for a large 10cm self-inflating mattress, I would recommend this model.

Velice příjemné spaní, jak doma v posteli. :-)
