This is a great success! It is, however, that an inflatable bed! This seems common at first but, once inflated with the electric pump (approx. 4-5 minutes) it is in the presence of a real bed (setting as possible firmness) with a height quite significant for the survey and seat. A bed that does not move, that does not crunches and remains inflated ....! even after four days of sleep (another couple) and games (4 rampaging kids!). In addition, lightning delivery! (Within 48 hours). I highly recommend this product, which is to buy with confidence! PS: Think of a fitted sheet 160cm
