King size bed bases

Choosing the right king size bed 

With a king size bed, you have extra space to turn over, adjust your sleeping position and stretch out comfortably. The right king size bed frame for you will depend on your personal preferences. Everyone’s sleep and relaxation habits differ, but some things you may want to think about include: 

• Your space. You’ll need to choose a king size bed frame that fits appropriately in your space. You don’t want things to feel too cramped, so you should leave some room for getting around the bed. 
   
• Your storage needs. Our king size beds are available as divans, with 4 drawers of side storage, and ottomans, which offer ample underbed storage. 
   
• Your lifestyle. You can also choose an adjustable bed frame for reading or relaxing. King size adjustable bed bases generally require two 75 cm x 200 cm mattresses, also known as small singles. Some TEMPUR^® king adjustable beds have frames that lock together, so you can have just one 150 cm x 200 cm king size mattress if you prefer.  

What are the dimensions of a king size bed frame? 

A king size bed frame in the UK is made to fit a mattress that measures 150 cm x 200 cm – or, 5’ x 6’6’’. It’s 15 cm wider than a standard double bed, so you have more room to stretch out.

When looking for your bed frame, it’s important that you choose the right king mattress to fit it. You don’t want the mattress to be smaller than your bed base.
