  • King Size Mattress Size | Standard UK 150×200 cm – House of Isabella

King Size Mattress Size

A king size mattress size refers to the standard dimensions of a mattress designed to provide generous sleeping space for couples or individuals who enjoy extra room. Understanding the measurements helps in selecting the right bed frame, bedding, and bedroom layout.

Quick Facts

  • Standard UK king size mattress: 150 cm × 200 cm.
  • Larger than a double mattress (135 cm × 190 cm) but smaller than a super king (180 cm × 200 cm).
  • Suitable for medium to large bedrooms.
  • Compatible with UK king-size divans, bed frames, and headboards.
  • Provides ample space for two adults to sleep comfortably.
  • Works with king-size bedding including sheets, duvet covers, and mattress protectors.

Why It’s Popular

King mattresses are popular because they offer extra width and length, ensuring comfort for couples and reducing disturbances from a partner’s movement. They provide flexibility for sleeping positions and are ideal for those who prefer spacious beds.


Popular Variations

  • Standard UK King: 150 cm × 200 cm.
  • Super King: 180 cm × 200 cm, for ultimate space and comfort.
  • European King Sizes: Slightly different dimensions; check before purchasing.
  • Adjustable King Mattresses: Compatible with adjustable bed bases; dimensions may vary slightly.

How to Choose

  1. Measure Your Bedroom: Ensure the bed fits comfortably with space for furniture and movement.
  2. Select Mattress Type: Memory foam, pocket sprung, hybrid, or latex depending on comfort preferences.
  3. Consider Firmness: Soft, medium, or firm options based on sleeping style and support needs.
  4. Check Bedding Availability: Ensure fitted sheets, mattress protectors, and duvets match the 150 cm × 200 cm size.
  5. Match Bed Frame: Ensure the mattress fits the chosen divan, frame, or storage bed.

Styling Tips

  • Pair with a king bed frame or divan for a coordinated and luxurious look.
  • Use layered bedding, including throws and cushions, to enhance style and comfort.
  • Choose bedside tables proportionate to the bed’s width for balance.
  • Add a rug under the bed to define the sleeping area and add texture.
  • Use a headboard to create a focal point and elevate bedroom design.

Benefits at a Glance

  • Generous sleeping space for couples or individuals.
  • Reduces disturbances from partner movement.
  • Compatible with UK king-size frames and bedding.
  • Suitable for medium to large bedrooms.
  • Wide variety of mattress types and firmness levels available.

⭐️ 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.
