Hello everyone. First Post here. The question I have is I bought the 4 layer zoned mattress blended latex from Flobed. Under it I bought the Euroslat Foundation and I am worrying now that its to thick a mattress to get any benefit from it. Will I get anything at all? Or would the cheaper flat slat foundation  been just as good. Bed is E.king with  x-firm>firm>zoned layer>convoluted topper. Thanks for any info.
