The king-size mattress is the most popular bed size in the UK. They are widely available and provide a lot more space for sleeping than a standard double mattress.
A big bed, the king-size measures 5'0" x 6'6. But a king-size bed is only a viable option if you have enough bedroom space. Therefore, in the UK where bedrooms are relatively small compared to countries like the US, most homes will only have adequate space for a king-size bed in the master bedroom.
King Size Beds for Restless Sleepers
This 5ft mattress is ideal for people who like to stretch out when sleeping or couples when one or both partners is a restless sleeper.
The king-size bed is also a perfect size for taller people, as all smaller standard UK bed sizes are 6ft 3" in length. At 6ft 6", the king-size gives taller people those extra three inches to spread out for a great night's sleep.
