My "friend' borrowed my very expensive air mattress and somehow "punctured it on the radiator"    Sounded suspicious to me too. Any how I needed a replacement quick. I wanted quality but I did not want to spend a ton on a replacement because I have been told it will be replaced. (remains to be seen). It came quick it's well made and was a great price. It will go nicely with my other if it ever in fact gets replaced.
