Hi, will a coolblue mattress topper work on top of your origins pocket sprung mattresses? My partner and I both like the dead feel of memory foam but our last memory foam bed has only lasted 3 years and now we are sleeping in little pits! we want a bed that doesn't transfer movement, is medium firm, turnable but with the memory foam bed feel to it too. The combination of the cool blue ( i sleep a little hot sometimes ) seems like the best option but will it work and what issues may we have? Our bed size is supering so we were thinking two zip links would also help. Will we feel the link and will the bed sink if we are both in the middle? Many thanks J
