My husband and I both were having difficulties sleeping... and had looked into different options... this was our first option, and so far, so good!!! Yes... it smells when it's first opened, and we made the mistake of covering it up... but we had to sleep on it, so we kept pulling back the sheets for a few days to air it out... it DOES get better! And it is also very WARM... which is great NOW... in this freezing temperature we are having... but not sure what is going to happen when summertime rolls around. But we are both enjoying the topper and have highly recommended it to others! I have a REGULAR king size bed, and thought it wouldn't fit my mattress very good, but it actually fits it perfectly. SO... I think the dimensions may be off... but it worked out good for me. My sister has a California King, which I believe is longer, and narrower, so I told her, it might fit her bed a little differently! I really wasn't worried about it being a little too short either way, but it's not! Anyway... all in all, we are loving the topper! And the price was VERY good... I really did my research and this was a great value.
