Key benefits

Key Benefits of the Sleepeezee Tranquil 1600 King Size Mattress

  • More room each than a UK double: You get 75cm each rather than 67.5cm, which means 7.5cm more of your own space, enough to stop elbows meeting when you both turn over.
  • Less disturbance on split schedules: If one of you is up well before dawn, the individually moving springs and the extra width help keep that early start on one side of the bed.
  • Length for taller sleepers: At 5ft x 6ft 6in, the UK king is 10cm longer than the UK double, so feet stay on the mattress rather than hanging over the end.
  • Space to change position: During pregnancy or while recovering from an injury, a spare stretch of mattress for extra pillows and slow repositioning makes nights a little easier on you both.
  • Lighter room demands than a UK super king: You keep most of the benefit of a bigger bed, although the UK king gives 15cm less each than the UK super king and needs a smaller room.

Who should buy the Sleepeezee Tranquil 1600 King Size Mattress?

This size suits you if...

You share the bed every night and keep waking when your partner moves, one of you is over 6ft and has run out of length on a UK double, or you need spare room for pillows during pregnancy or recovery.

Consider another size if...

Your bedroom is under our suggested 2.7m x 2.9m, or you each want more than 75cm. We'd recommend the UK double for tighter rooms, or the UK super king for 90cm each.

FAQ's

Frequently Asked Questions About the UK King

Is the Sleepeezee Tranquil 1600 UK king long enough for someone over 6ft?

The UK king is 200cm long, 10cm longer than the UK double and the same length as the UK super king. If height is your main concern, you get the full extra length here without paying for the extra width of the UK super king.

Will I feel my partner move on a Sleepeezee Tranquil 1600 UK king?

Probably less than on a smaller size. The 1,600 pocket springs respond individually, so movement tends to stay where it starts, and the UK king puts 75cm between you rather than 67.5cm on the UK double. Restless sleepers may still be felt a little, but the extra width helps.

Tranquil 1600 UK king or UK super king for a couple?

The UK king gives 75cm each and the UK super king gives 90cm each, so the UK king has 15cm less per person. If a dog regularly shares the bed, the UK super king may suit you better, but it needs at least 3m x 2.9m of floor space.

How much extra space does the Sleepeezee Tranquil 1600 UK king give over a double?

The UK king is 15cm wider and 10cm longer than the UK double. Shared between two, that works out at 7.5cm more each, which you notice most when you both roll onto your sides at once.

Will a Tranquil 1600 UK king fit in a new build main bedroom?

We suggest at least 2.7m x 2.9m for a UK king, and 3.2m x 3.2m if you want it to feel comfortable. New build bedrooms often seem smaller once wardrobes are fitted, so measure the clear floor space, not the room plan.
