I had shoulder surgery in December and Physical Therapy for 4 months.  As a celebration for ending my physical therapy we took a trip to Las Vegas and stayed at an upscale hotel.  They had pillow mattresses that really soothed my shoulder injury.  Since I didn't want to buy an entire new mattress I decided to purchase the bed topper.  It is absolutely great.   Fits the bed perfectly and insures a great night sleep on that shoulder that was operated upon.  Thanks for the great addition to our mattress.
