Inflatable lounger (deflates quick (SG4 hitchin)

We have this inflatable lounger thing that can be inflated with the cold setting on a hair dryer or you can swoop it around outside and trap air in it, but there must be a hole in it somewhere as it deflates in about an hour. Kids really like it though so if you’re happy to keep inflating every hour or so, then hopefully kids will enjoy it.
