A difference between the US and the UK is easily bed sizes. We had already been familiar with this difference and it played part in our choice to get rid of our memory foam super king in the UK as all the bedding would have been the wrong sizes in the US. Plus, it has to be one amazing thing to be worth taking across an ocean. We got rid of all of our furniture as a result, as none of it was impressive enough to be worth what it costs to get it across the Atlantic.
Over the course of our trip, we naturally stayed in dozens of different beds. Something we came away from realizing is that we always want a giant bed. Fortunately, Americans make it slightly easier to get this. It’s not just that the sizes are different. UK hotels are much less likely to offer things like a king bed. More than that, a UK king is more similarly sized to a US queen, with a US king being 76 in × 80 in and a US queen being 60 in × 80 in, while a UK king is 59 in × 79 in and and a UK super king 71 in × 79 in.

In an informal poll of my friends in both countries, Americans seemed more likely to expect a very large bed, both in hotels and at home, while the British are much less likely to have this expectation. I wonder if this is a space issue, as our super king just barely fit in our Brighton flat bedroom. The man who delivered our brand new king bed confirmed that Americans are buying lots of king beds, while we were the only people I knew in the UK who insisted on a super king. That said, if you are a light sleeper or have back problems in the UK, get yourself a super king. They sort out all manner of problems.
