Layer Details
- Cover. A deep quilted fabric treated with Purotex+, certified by Allergy UK to reduce dust mites and nasties by up to 96.6%. It also has an Adaptive fabric treatment to regulate temperature and wick moisture, which means less clammy overheating on warm nights.
- Latex layer. Plant-based, hypoallergenic latex that moulds to your body and relieves pressure. It also helps keep your spine aligned, which you'll feel as gentle contouring rather than sinking.
- Pressure-relieving memory foam. 30mm of memory foam with an open cell structure and 7 drill zones, which Eve says is 5 times more breathable than standard memory foam. The zones adapt to your body and encourage airflow.
- Dual spring system. 2,000 extra springs, a combination of tall pocket springs and shorter micro pocket springs. Together they add responsive, targeted support beneath the comfort layers.
- Reinforced edge support (firmer side). Reinforced edges on the firmer side, which means you can sit or sleep near the edge without feeling like you'll roll off.
- Firmer foam. A firmer foam casing on one side for a sturdier, more supported sleep. This is the side to use if you like a solid, stable feel.
- Reactive spring system. 1,000 full height springs, softer at one end and firmer at the other, each wrapped in a breathable fabric pocket. The pockets help prevent motion transfer, so a restless partner is less likely to wake you.
- Reinforced edge support (softer side). Reinforced edges on the softer side too, so edge stability doesn't change when you flip the mattress.
- Softer foam. A softer foam casing on the other side for a plushier, more squishy sleep. Flip to this side if you prefer to sink in a little.
- Base. A base with handy handles on the sides, which makes flipping and moving the mattress noticeably easier.

- 75cm each for two people sharing: At 150cm wide, the UK king gives each of you 75cm, which means you can shift position at night without brushing your partner awake.
- 15cm wider than a UK double: That 15cm sounds modest on paper, but it is the difference between negotiating space and simply having it, especially once a dog claims the foot of the bed.
- 200cm of length for taller sleepers: The UK king's 200cm length means anyone approaching six foot can stretch out without their feet meeting the end of the mattress.
- Pocketed springs limit partner disturbance: The 1,000 Reactive springs sit in individual fabric pockets, which means an early riser can get up without sending ripples across your side.
- Handles make flipping this size manageable: A king is a big thing to turn over, so the side handles matter more here than on smaller sizes when you want to swap between the softer and firmer feel.
- Edge support across the full width: Reinforced edges on both sides mean the outer stretch of that 150cm width is usable sleeping space, not a slope you avoid.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, one of you is close to six foot and keeps finding the end of the mattress, or you sleep on different schedules and want enough width that the first person up doesn't wake the second. It also suits couples whose bed routinely includes a dog taking more than its share.
Consider another size if...
Your bedroom is smaller than the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. The UK double would suit you better and still gives generous solo space.

Is the Eve Wunderflip UK king wide enough for a couple?
Yes, comfortably for most. The UK king is 150cm wide, which works out at 75cm each for two people sharing. Combined with the pocketed Reactive springs, which reduce motion transfer, it gives couples on different schedules a realistic chance of not disturbing each other. If you want still more room, the UK super king adds another 30cm of width.
Is the UK king Wunderflip long enough for someone over six foot?
It should be. The UK king measures 200cm long, 10cm more than a UK double, so a sleeper a little over six foot can lie flat without their feet hanging off. If you are well past six foot, the UK super king offers the same 200cm length with extra width, but no additional length.
Is the Eve Wunderflip hard to flip in a king size?
It takes more effort than a smaller size since you are turning a full 150 x 200cm hybrid with latex, memory foam and 3,000 springs inside. Eve includes handles on the sides of the base, which makes gripping and rotating it noticeably easier. Two people will find the job far more comfortable than one.
Will the Eve Wunderflip UK king fit 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, and that guidance is ours rather than Eve's. New build master bedrooms can be tighter than they first appear once wardrobes go in, so measure the usable floor space before committing.
Should we choose the UK king or size down to the UK double?
If you share every night and have the room for it, the UK king is the safer choice: 15cm wider than the UK double and 10cm longer, a difference you feel nightly. The UK double makes sense only where floor space is genuinely tight. Compare the retailers listed on this page, as prices are updated as they change.
