Not comfortable, hurts neck and back

Been trying to return product since I got it, it arrived in a damaged box, ups guy brought it in and helped me take it out the busted box, the plastic was already ripped open and a huge like wet coffee spot was on it as I’m pulling it apart. I thought it would be comfortable, but it’s not. It’s the worst investment I made. I should’ve checked around before purchasing from this company. The delivery guy made it seem like he tried to deliver it several times I had to wait 2 extra days, saying they missed delivery. I’m so disappointed in this product. I want a refund and to refund it. My elderly grandparents says their back and neck hurt even worse on it. This was a horrible mistake to purchase this product from this company.
