Just picked up a Duvalay from a chap on fb marketplace and its been sold to me as a 5cm freshtec. however, the foam is not memory foam at all and its not very dense. I have the blue eggshell foam from Amazon which feels a lot more supportive. The seller was age 60+ and from a nice house, in a nice area, which is the only thing convincing me it wasn't a scam. Even at 80 quid, its not great. This doesnt sound normal, but I'm stuck with it now. So thinking of ordering replacement foam from HOME PAGE has anyone tried their products before ?
