Thinking of purchasing a Super king sized base advertised as 192cm W x 212cm D and interested in purchasing your Super king zip & link mattresses - Comprising of 2 x 3’0 x 6’6″ - would your matteresses fit the bed base? My conversion maths may be out - not sure. If they do fit, can we order different choices, as my husband hates feeling 'hot' in beds that have non-breathable material. Thank you
