This is a great inflatable to use in a pool or the beach. I left it inflated for few days on purpose, even to see if there were small holes and noticed no problem at all.
This inflatable boat has also a "toy" that will distract and entertain your baby, really useful if isn't used or scared of staying in the water. I've seen similar products for at least double the price so I would consider this definitely a good deal!
The mom part is big enough to accommodate small/medium/large sizes. I tried it now that I'm pregnant and wasn't uncomfortable at all.
