The quality of the mattress is very good. Who needs, you should get the right air pump so. Otherwise you get when, aufpusten of mouth, briefly slight dizziness. But, also the type of Aufpustens is still feasible in size. That's the good part, of course, "NEW" sniffs, I think when unpacking the mattress, normal. Otherwise, the value for money is unbeatable ..... and do not forget: This is just an air mattress. ;-)
