Yep - wet test is a must, especially with lounges. Usually there is always a seat to fit everyone. But with only one lounge, they usually are designed to fit taller folks. You have to check overall length of the lounge, plus the length from hip to knee. If hip to knee is long, you may not be able to bend your leg naturally, almost guaranteeing you'll float and not be comfortable. I know first hand from wet testing.
