COOL GEL Hybrid 12" Pillow Top Mattress

Updating my review. One month later the mattress continues to sag in the middle becoming more and more uncomfortable. My back is just killing me and as a senior on a fixed incomeI can’t afford another mattress. It was Amazon that decided I could not return the mattress even though I was within the three month return time when I contacted them. Because I was not going to be at home when they needed to pick it up, I was not allowed to return it. I would love any ideas about how to follow this up. I have talked to Amazon customer service with the result. I just mentioned. When I contacted the seller, I was told I had to work through Amazon. This is having terrible consequences for me. I was really hopeful about this mattress when I read so many great reviews. First, I will mention that my mattress looked nothing like the one in the pictures. It was very comfortable for the first month that I had it. Although it is not sagging a lot, it is noticeably starting to not be flat. I think this might be satisfactory for some people, but I have a back and hip injury and I need to have a firm surface underneath me. I am a single sleeper in this bed and a bit heavy. It might not be so bad for a smaller person or two smaller people who would even it out. The price was very good I tried to return it when the return date was still a week away, but they needed to pick it up from me a week later and I was traveling to my daughter‘s for three weeks. They basically told me I could try to return it when I got back, but that it would not be likely that it would be accepted. Then they sent me return information to complete immediately, so I never followed up. I thought I had posted this review but when I came back now to update it, I see I had not submitted it. So now, a month later, it is sagging even more. I’m very disappointed and it’s challenging trying to find another affordable mattress. I wish I had kept my previous one.
