The pad serves its purpose: it keeps tight and fits well on our 180x200 mattress. Who the cozy feeling of a warming mattress cover was used, however, have to get used to the rather cool sun feeling is first. And you sweat no more, but because the fabric is very thin (thickness Lake), the mattress protector is already EHR times sweated wet. We have laid a quilt on it that also absorb some sweat and easy to clean and should be replaced with low heavy contamination.
