I ordered 2 pieces of this inflatable mattress, unfortunately, these mattresses have endured not long. 1 mattress just 1 week second mattress 3 weeks. Both mattresses have the air let out. I have worked and glued the holes, a short time later the mattresses have let out the air at new sites and I'm not the heaviest man and weigh only 80kg. So do not touch and would rather pay a little more and take better quality or their weighs significantly less than I
