Query: Not good.

Only the outside appearance of the product is good. It is not good quality, even if you do not use it, and leave it somewhere else on its own, without putting anything on it, it deflates in just a matter of hours. I tried two and both are the same. So, if you do not want to buy something that is not usable, then definitely avoid this one.
