J bought this mattress to test it in anticipation passages nieces and nephews celebrated for christmas. It inflates very quickly, connection is easy and comfort is very satisfactory. It's true that it's a bit noisy at times of inflation, short, fortunately. It's true that inflated, it is bigger than what I imagined: it has the dimensions of a single bed and not an extra mattress, but that's probably why he's comfortable. Easy to store and also after ... Very happy with the product. I bought a second.
