A nice water bed for my 4 month old. He laid comfortably on his tummy with his paci in his mouth. I did notice when his big brother placed him down on it he lifted his head up really high unlike what we’ve seen. It’s really heavy with the water in it. My 10 year old son also blew the air in it, and he filled it with water himself in the bathroom so it is easy to get it inflated with air and water. There’s a vent for the air and another for the water on the underside.
