Key Benefits of the Sleepeezee Tranquil 1600 Super King Mattress

  • 90cm each for two sharing: Each of you gets 90cm of width, which means a partner who turns over repeatedly is simply further away rather than rolling into your side.
  • Springs that move on their own: The 1,600 pocket springs respond individually, so across a bed this wide, movement on one side usually stays on that side instead of travelling across to you.
  • Space for small visitors: When a child wanders in during the night, two adults can still keep a workable share of the mattress without anyone ending up clinging to the edge.
  • A proper bed for a large room: In a big master bedroom or a period property with high ceilings, a UK king can look a little lost, and the UK super king fills the space in proportion.
  • Extra length over smaller sizes: At 6ft 6in long, the UK super king is 10cm longer than the UK double, which helps taller sleepers keep their feet on the mattress.

Who should buy the Sleepeezee Tranquil 1600 Super King Mattress?

This size suits you if...

You share with a partner whose tossing and turning regularly wakes you, or children and a large dog routinely join you overnight, and your bedroom gives you at least 3m x 2.9m to work with.

Consider another size if...

Your bedroom is smaller than 3m x 2.9m, or you rarely share the bed. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Super King

Is the Sleepeezee Tranquil 1600 UK super king big enough for two adults and a child?

For occasional visits, yes. Two adults get 90cm each, so a small child climbing in at night has room to settle between you. Because the 1,600 pocket springs move independently, a wriggling child is less likely to jolt either of you awake, although a bed full of three every night will still feel busier than two.

Sleepeezee Tranquil 1600 UK super king or UK king: which should I buy?

The UK super king is 30cm wider than the UK king and the same length, giving 15cm more each when two of you share. That extra width suits restless sleepers or regular visitors. The UK king needs less room, though: we suggest at least 2.7m x 2.9m for it, against 3m x 2.9m for the UK super king.

Does a UK super king pocket spring mattress help with a restless partner?

It helps in two ways. The width gives you 90cm each, so there's genuine space between you, and the pocket springs work individually, which usually limits how much of your partner's movement reaches your side. Distance tends to matter more than anything else here, and a UK super king gives you the most of it in this range.

Will a UK super king fit in a loft conversion bedroom?

Only if the full-height part of the room is large enough. We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable. In a loft conversion the sloping ceiling usually decides which wall the headboard goes against, so measure the floor space where you can stand upright, and check door swing before committing.

Is the UK super king the largest Sleepeezee Tranquil 1600 size?

Yes. The Tranquil 1600 comes in five sizes, from UK single up to UK super king, and the UK super king at 180 x 200cm (6ft x 6ft 6in) is the biggest. If you need more space than that, you would need to look at a different mattress, as there is no larger size of this model.
