I read through all the reviews on this and similar mattress toppers before making my final decision. This particular brand sounded so good from what others reported that I thought it fine to take a chance. Besides, as a regularly returning Overstock customer, I know how reliable the customer service is here should I have a problem with the purchase.I had broken a foot a year earlier, and the compensating joint pains and arthritis that developed all over the rest of my body due to my severe decrease in daily motion had become an overwhelming situation. I was beginning to wonder if a gal in her 50s was going to be relegated to a life of pain, no matter how much I worked with therapeutic exercise. The funny thing is, I am a huge believer in proper therapeutic exercise and a certified postural alignment specialist, so I know how to help myself and others who live with many forms of chronic pain due to joint and alignment issues.I had read about the funny smell to the new mattress topper but didn't care. When the topper arrived, I excitedly tore off the protective wrapper and threw it on top of my bed to plump up and air out. The odor was never a problem to me and really did quit by the second day. By dusk, I made up the bed with the new topper and threw myself into it. I kid you not, I imagined I was actually surrounded in a cloud, just like I used to imagine as a child. So I drifted to sleep with all my usual and sundry joint and muscle aches. When I awoke in the morning and got out of bed, what a surprise to find that I didn't have that awful, stiff and achey shuffle to work through for an hour or so before I could really get going with the day. There was no hip pain, no ankle pain. I had to drive for some errands that morning, and I kid you not, the memory of the soothing sensation of that mattress topper was so strongly etched into my senses that I thought there was a cushion behind my back. I had to look behind myself to see if a back cushion had mysteriously appeared without my notice as I stepped into the car.The chronic severity of my joint and muscle aches has not returned after that first night. It's been years since I was remotely interested in staying in bed for more than a few hours at a time because my body aches would demand that I get up and move. Now I have to force myself to leave the bed, it feels so good. I think I'll enjoy the extra cloud time for a bit longer. I'm due.I raved about my experience with this product to my elderly parents, who immediately asked me to put in an order for their own bed. They too report they have experienced a high degree of immediate body ache relief. Now I'm watching to learn how long this topper's qualities will last.
