Very disappointed

I have owned many gravity chairs over the years. Some heavy duty, some not. This one is very uncomfortable and difficult to recline and stay reclined. The angles are wrong for being a comfortable gravity chair. It makes me feel like I am slouching and your lower legs at a steep angle. Wanted to return it to Amazon but they won't let me. They say this item can't be shipped back because "the item contains flammable liquids or gases and can't be returned to Amazon".. So my question is, how did they ship it to me but I can't ship it back?? Frustrating.....
