I thought I ordered the padded Sensacool mattress cover, but ordered the latex-backed Sensacool protector. BIG DIFFERENCE!!! I had been using the padded cover on my king bed for a couple years which held up so well and kept my bed cool HOWEVER, with the unpadded, latex backed Sensacool mattress protector, we wake up sweating! I took them back and am waiting for the padded ones to arrive. For the record I had to order new ones because we got a split king adjustable bed, or Id still be using it. I washed it and gave it to my daughter for her bed and her and her husband absolutely LOVE IT!! She says it keeps them nice and cool because their memory foam mattress gets hot at night. She couldnt believe the difference. Get the padded Sensacool mattress cover, not the Sensacool mattress protector, and you wont be disappointed!!
