Query: medslant pillow

I bought this pillow because my sister said she bought the same one off Amazon but she lives in London. When I first got the pillow it seemed like cheap foam so I was disappointed and wanted to send it back. I then realized I couldn't send it back because it was a pillow. I did finally get connected to someone at Medslant who was very thorough in explaining the foam and its density and quality. So, I tried the pillow for a few nights and found it to be very comfortable. It did seem to help me with my reflux. I would probably buy this product again if the price was lower. I feel this pillow is over priced and would expect it to be around $59.99. The outer cover is necessary for comfort and washability. I was happy they sent me another cover to rotate for washing.
