I have received this command, and this mattress seems to me excellent. Card only to try it I will wait for the inflation mouth, because the mattress is delivered without? It is inconceivable and unacceptable. I admit that the pump is an option, but not the tip anyway !!! I had a universal electric pump (12 V) with + eral tips, the most used, unfortunately none matches this mattress. Serious lack. I have to go in search of this ad-hoc tip.
