It big lIKee very big which takes FOrever to fill with air which take about ten minutes which then you have to put the person inside which the fill then fills back out causing you have to fill it up more once you inside it and the air is rushing in it feels very castrophobic and LoUD but even then when you are inside on top the waterit feels azmAing like you are floating in the clouds and you can just close your eyes and float wouldn't recommend two people but would be fun for a drunk party with party lights inside of it only fun for about 30 mins then you have mixed feelings about how long ITT took to get in and out which is very difficult. Still pretty decent need a big storage shed to keep this thing in too .
