  • King Mattress Size in Centimeters | UK Standard Measurements – House of Isabella

King Mattress Size In Centimeters

The king mattress size in centimeters refers to the standard dimensions of a king-size mattress, commonly used for bedrooms that require generous sleeping space for couples or individuals seeking extra comfort. Understanding the measurements helps in choosing the right bed frame, bedding, and room layout.

Quick Facts

  • Standard UK king mattress size: 150 cm × 200 cm.
  • Provides ample space for two adults to sleep comfortably.
  • Compatible with UK king bed frames and divans.
  • Bedding, mattress toppers, and protective covers are designed to fit these dimensions.
  • Larger than a double (135 cm × 190 cm) but smaller than a super king (180 cm × 200 cm).
  • Ideal for medium to large bedrooms.

Why It’s Popular

King mattresses are popular because they offer extra width and length, enhancing sleep comfort for couples and those who enjoy more space. They reduce disturbances from a partner’s movement and accommodate a variety of sleeping positions.


Common Variations

  • Standard UK King: 150 cm × 200 cm
  • Super King: 180 cm × 200 cm, for larger bedrooms or ultimate comfort.
  • European King Sizes: Slightly different dimensions; always check before purchasing.
  • Adjustable Beds: King mattresses compatible with adjustable bases may vary slightly in size.

How to Choose

  1. Measure Your Room: Ensure enough space for the bed frame, walking paths, and furniture.
  2. Select Bed Type: Divan, upholstered, or platform beds are all compatible with standard king mattresses.
  3. Consider Sleepers: Ideal for two adults or those who prefer more personal space.
  4. Check Bedding Availability: Sheets, duvet covers, and mattress protectors should fit the 150 cm × 200 cm dimensions.
  5. Think About Mattress Type: Memory foam, pocket sprung, or hybrid mattresses may affect depth and comfort.

Styling Tips

  • Coordinate with matching upholstered bed frames for a luxurious look.
  • Add layered bedding, such as duvets, throws, and cushions, to emphasise comfort and style.
  • Choose bedside tables proportionate to the bed’s width for balanced aesthetics.
  • Use rugs to define the sleeping area and add warmth.
  • Incorporate lighting, such as bedside lamps, to complement the king mattress’s presence in the room.

  • Extra sleeping space for couples or individuals seeking comfort.
  • Compatible with standard UK king bed frames and divans.
  • Reduces sleep disturbances with generous width.
  • Perfect for medium to large bedrooms.
  • Wide variety of mattress types and bedding options available.

Gold placemats

I recently purchased these gold placemats and I’m really pleased with them. They add a subtle, elegant touch to the table without looking overly flashy, with a warm gold tone that works beautifully with neutral decor; they’re also practical, easy to wipe clean, and durable enough for both everyday use and hosting, making them a great balance of style and functionality.

⭐️ Beautiful chair, great service & communicator

Such a great find!… I came across this company by chance and I’m really glad I did.

Communication was clear from the start, especially around delivery, which made the whole process feel reliable and straightforward.

The chair is excellent quality and a lovely addition to the room.

I’d happily recommend and order again.
