The sleeping comfort the mattress is fine. The surface coating is not located in their own effluvia, such as may be the case with other models on warm days. However, the mattress must be re-inflated or pumped in daily (annoying if you have a three-day visit). However, the only real downside is the pump: The battery is quite powerful and can even be charged via the car cigarette lighter, but the pump does not work with direct AC supply. This means that if you want to use the mattress at home surprisingly (spontaneous visit, etc.), the battery must be always fully charged (that means to discharge it every six weeks and recharge, to keep it ready for use), or it takes 10h charging time until the mattress can be inflated. Since I do not want to deal every six weeks with the mattress, she was sometimes temporarily not operational.
