@JulesandBadger Welcome to the community forum. I would put the actual bed measurements, in metric and imperial. Often those who know inches don’t know centimetres and vice versa. Sitters from the US, who aren’t aware there would be a difference, will assume a king is a king, whereas a UK king is about equivalent to a US queen. A US king is far bigger again, and now quite common in the US. If you have international sitters, they may be taken aback by how small your king is.
