The DERYAN self-inflating mattress is super handy. No need to bring a pump because it inflates all by itself! Just open the valve to fill the mattress with air. Once it's full, close the valve again. After use, open the valve again, roll up the mattress to squeeze out the air, and then close the valve again.

Please note: So, no need to blow it up yourself! Inflating it yourself can cause irreparable bubbles in the mattress!
