Factors to consider for a King bed

Before you choose your King bed there are a number of considerations for this bed size listed below:

  • Space: Room space is a key factor when people consider the size of the bed they want to purchase.  
  • Number of people: One person meeding a mattress will generally opt for a single, Double or Queen (for those wanting a bit of a luxurious space). For two people, a Queen and King are the most popular.  The Super King is the one of the fastest growing bed sizes - it can fit 4 people!  
  • Age of person: Kings are generally a bed for couples.  The most popular size for a couple is a Queen.  Whereas, a Single will suit children.
  • Size of person: A larger framed person is likely to enjoy a larger mattress with extra space so the King will be perfect. 
  • Sleep style: If you are a combination sleeper and move around during the night then you should consider a larger mattress or one that limits zero partner disturbance.  Also, if you are a hot sleeper you may like to have some extra space.  This is another advantage of a King bed size over a Queen. 
  • Weight of mattress: Most mattresses require you to rotate them every few months.  So having a mattress you can lift is important. Unfortunately, given the size of the King mattress they are generally very heavy!
  • Bed Frame: If you own an existing bed frame you may want to keep this so your choice will be decided by what you have - most couples will have a Queen.
