This is one of those decisions that sounds simple until you are standing in your bedroom with a tape measure, trying to work out whether a king size is actually going to fit without the wardrobe door becoming decorative. Then there is the added layer of deciding between a king and a super king, whether a small double is a sensible compromise or something you will quickly outgrow, and what a European king size actually is and whether you need one. If you have started browsing different mattresses<\/a>, you will have seen just how many options there are.<\/p>\n\n\n\n
