I purchased this because our mattress was getting old and we tended to roll toward the center. When I first unrolled it, it did have a smell, but it went away quickly and took about 24 hours to expand to full size. I loved it immediately, but my husband wasn't so sure. He thought it was too soft at first. We slept on it for 1.5 years with no problems. Between the 1.5 year and 2 year mark, I noticed it having several small rips in it. Finally, after 2.5 years, we had to throw it out because it was torn so badly. We didn't plan on buying another as we had purchased a new pillow-top mattress. But after sleeping only a few nights on it without the memory foam, both my husband and I decided we had to invest in a new one. We loved the first one so much, we decided to just go with the same exact brand and style.
