Junk Avenli Flocked Airbed Double Size

Double size for 2 people.
Used indoors twice.
I purchased this new about a month ago, but after a few hours from the first day, it seemed to be losing air.
There don't appear to be any holes or scratches.
I'm not sure if the air valve is defective, but it can be used for several hours, so I'm looking for someone who is okay with that.
Comes with a manual pump.
The item will be shipped without the original box, packed securely.
