I have been wanting to show this photo for a long time. 

It reveals the rise of the lounger to offset flotation.  To stop floating you keep the lounger not too deep, keep the back so it is not laid back too far, lower the bottom and raise the legs.  The loungers in the Haven Spas are raved about by our spa owners.  Many have wet tested all the competition spas in their areas and the report is our lounge is the best from their words, not mine.  I love the lounge!  Notice the left hand "reverse molded" arm rest.  This really helps to support the users in the lounge.  See the new 100 Sq Ft filter!
