Welcome to our forum.
I went with the Jacuzzi j-480 because of the lounger , and in this particular model it really does not take up a whole side like most spa loungers do, you get four corners, like in the J -470 only the lounger seat lets you stretch out a bit in that corner , you do lose one very small seat with one jet in it to make room for your feet , but you gain the two foot jets and the calf and wrist jets and also two more calf jets in one of the corner seats . loved the lounger.
I would agree with Spatini, if you want a lounger take a look at the J-480. It does not take up the whole side of the tub and IMHO would get used more than some loungers.
IMO, there's not a better seat in the spa than the lounge to watch a starry sky or, better yet, a great meteor shower! 8-)
Or more often, Iridium satelites or the International Space station.http://www.heavens-above.com
