Quechua Arpenaz Comfort Self-Inflating Mattress - 4 Season in Green, Size 75" x 25.5"

A self-inflating mattress consists of an airtight envelope glued to an open cell foam in which the air circulates. When you unfold the mattress, it will return to its original shape and thickness (4.5 cm for the AG Comfort) and fill with air accordingly. However, it requires some mouth inflation so you can adjust it to the pressure level suitable for you. Self-inflation is more or less noticeable depending on the thickness of the mattress. | Quechua Arpenaz Comfort Self-Inflating Mattress - 4 Season in Green, Size 75" x 25.5"
