First of all, the mattress is really very narrow! BUT: Who would have thought that a narrow mattress brings more fun than a width? When I tried them for the first time, I was only barely able to rise, as it tends to tip over. But after a few failed attempts, makes it really fun to have to enforce against the waves and the mattress :) Not only lazy lying around, but active "kämüfen with mattress" is the Deviese. But that does not mean that it is impossible to lie sometimes relaxing on the air mattress. If you have the hang of it, is also not a problem :) In addition, I must mention that the mattress can withstand a lot of weight! I'm really not a flyweight, but the mattress has not only supported me, but sometimes the extra weight and my girlfriend without breaking it! Conclusion: Affordable, durable and fun. But even very narrow :)
