For years I have tossed and turned all night long.  I would wake up several times and have trouble falling back to sleep.  I assumed this was just a part of aging until a friend  mentioned that she had purchased the Serta foam mattress topper and what a difference it had made in the quality  of her sleep.  I bought one or myself and sleep soundly through the entire night!  I can't believe what a difference this product has made!
