...Thought we had to buy a new bed...our new Slumber Solutions Gel Foam Pad has changed our entire sleeping surface !!! ...I suffer with chronic low back pain..many years...pain scale 10+...with the acquisition of our new Gel bed pad..my pain scale reduced to a 3 !!!! I can get out of bed each morning way easier than before and go about my day with much greater mobility than ever before !!! ...We were going to choose just a foam topper until I researched (here on this site) the Pros and Cons of Gel Foam vs Regular Foam Pads. ...The cost was considerably more than just a foam topper..BUT...was well worth the extra investment !!! ...As advised by the manufacturer (and us!!) you must air out this Gel Foam Pad as it does have a strong odor. We aired it out lying across the top of our bed for one full day (flipping it once). ...Added BONUS..the Slumber Solutions Gel Foam Pad came with a beautiful 100% Egyptian Cotton zippered "pocket" cover !!! It was a bit tricky to get the gel pad inside the cover, but with patience and preferably 2 people it can be accomplished easily !!! We removed the Gel Pad from lying across the bed and placed it across our Sofa...Next pull the elastic binding (which goes all the way around the BOTTOM of the Egyptian Cotton cover) and pull it over the existing mattress and box spring..as if it were a fitted sheet!!! If you do it correctly you will see the zippered satin trimmed box edge square of the Egyptian Cotton cover..on top. ...Unzip the cover (zipper only opens one width and one length..not all the way around)...we placed the Gel pad back on top of the cover, folded it in half then worked it into one end of the Egyptian Cotton Cover followed by the other end into the cover. When properly placed inside the Egyptian Cotton Cover; zip it up and it's ready for sheets and a magnificent nights sleep !!! ...P.S. Another PLUS on owning a Gel Foam Pad is the cooling design which transfers heat away from your body and disperses it into the pad...great for those of us who "suffer" with night sweats !!! ...Oh yes and saved us $$$ because we were going to buy new bedding and this new pad saved us hundreds !!!....Highly Recommended !!!
