not happy

I never write reviews, but this was worth sharing. The bed was so comfortable the first night, but within 3-4 months I noticed that my side was sagging. I tend to sleep in the same spot on my side, but I am 120 pounds, so that is likely not the issue. We spin the mattress often since my husband moves around alot and his side has held up much better. we are at almost two years, and at this point if I lay in the middle it feels like I am so much higher up, it is very strange. A friend told me I could actually call for a replacement, but we no longer live in New York. I am so dissapointed, because the first few weeks were great!
