Extremely uncomfortable. There is a 2-3 inch gap between my lower back and the chair - which means no lumber support at all. My wife experienced the same thing. Also, the angle of the lounger caused our bodies to slide down - resulting in even more discomfort. The designer created a good looking lounger, but obviously did not care anything about its total lack of ergonomic qualities. I noticed a couple reviews that said the lounger is comfortable, and that they used it in the pool. The only thing I can think of that would make it seem comfortable is that the people’s bodies were partly floating. This, they did not notice the ridiculous lack of lumbar support. Plus, they probably did not slide down for the same reason.
