Key benefits

Key Benefits of the Emma Original King Size Mattress

  • Room to sleep apart, together: With 75cm each for two people sharing, you can both change position freely instead of negotiating for the middle ground all night.
  • Pocket springs help with different schedules: The 5-zone pocket spring core responds to each body individually, which means an early alarm on one side transfers less movement to the other.
  • Extra length for taller sleepers: At 200cm long, the UK king adds length over the 190cm UK double, so a taller partner's feet stay on the mattress rather than off the end.
  • Usable edges across the full width: The foam edge around the springs firms up the perimeter, so the outer stretch of this 150cm width is proper sleeping space, useful when a dog claims the middle.
  • A washable cover at family scale: The removable, washable cover is a practical touch on a bed this size, where spills and pets are more likely to feature over ten years.

Who should buy the Emma Original King Size Mattress?

This size suits you if...

You share every night and the UK double has started to feel like a compromise, with one of you woken by the other's alarm or an early start. It also fits if either of you is tall enough to want the 200cm length, or if a pet routinely takes a share of the bed and you'd rather not fight for space.

Consider another size if...

Your bedroom is smaller than our suggested minimum of 2.7m x 2.9m, or you sleep alone and don't need this much width. We'd recommend the UK double of the Emma Original instead, which keeps the same medium hybrid feel in a smaller footprint.

FAQ's

Frequently Asked Questions About the UK King

Is a UK king Emma Original big enough for a couple?

Comfortably, for most. You get 75cm each for two people sharing, which is enough to turn over without disturbing your partner, and the 5-zone pocket springs keep movement fairly localised. If one of you sprawls or a dog joins in most nights, the UK super king, 30cm wider than the UK king, is the roomier option.

Will the Emma Original king fit in my bedroom?

We suggest a room of at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m feeling comfortable. That allows walking space on both sides and room for bedside tables. New build master bedrooms can be tighter than they look once fitted wardrobes go in, so measure the usable floor rather than the whole room.

How much bigger is the king Emma Original than the double?

The UK king measures 150 x 200cm, so it's 15cm wider than the UK double and 10cm longer too. The extra width is what most couples notice night to night, while the extra length is the real gain if either of you is approaching six foot and tends to reach the end of a standard 190cm mattress.

Is the Emma Original king good for a tall sleeper?

The length is the point here. At 200cm, that's 5ft x 6ft 6in in imperial, a UK king gives a taller sleeper room to stretch out fully, which the 190cm UK double doesn't. The medium hybrid feel suits most positions, although a very tall, heavier back sleeper may prefer to try it via the trail of retailers listed on this page.

Does the king size Emma Original cost more than smaller sizes?

Larger sizes of the Emma Original do cost more than smaller ones, and prices for the UK king move around between retailers. Rather than quote a figure that could be out of date tomorrow, compare the live prices shown on this page, which are updated as retailers change them.
