The only reason I gave it a 4 instead of a 5 is bc I wish that the memory foam was just slightly thicker; but my husband thinks it's just perfect. I used to wake up with that needles-in-your-foot feeling every morning when my feet touched the floor and both my husband and I could not get a good nights rest with our mattress...knew it was time for a new one. However, we decided we would try a more affordable alternative solution before we took that $1000+ step towards a new mattress and opted for this highloft purchase. We were not disappointed. Changed our lives! Immediately started sleeping well and NO MORE pins and needles in my feet when I woke up!! The only con is that it does retain heat and if you get hot in the night, this will make you hotter. Nothing kicking the covers off you during the night, can't solve. Worth getting a bit hot in the night over body aches and horrible sleep. And for the price?!! You can't go wrong!
