Our mattress is over 10 years old and needed to be replaced, but we did not have the money to do so. My husband was waking up with back pain every couple of hours and was exhausted heading to work. I have many painful health issues, and it was becoming impossible to get any sleep on that old mattress. I purchased this topper based on reviews, and WOW!! I am so glad I did. My husband is happier, sleeping much better, waking without pain, and I too am sleeping better. THANK YOU TO OVERSTOCK.COM FOR SUCH A GREAT DEAL ON A WONDERFUL MATTRESS!!
