Layer Details
Hand-Stitched Tufted Cover
Handmade in the UK from premium viscose, with handles stitched into the sides. Those handles matter more than they sound, because this is a mattress you'll want to rotate and flip regularly.
Needle Felt Layer
A naturally breathable, insulating layer that helps regulate temperature. In practice that means it holds warmth in winter and lets heat escape in summer.
Comfort Polyester
A lightweight, durable layer that improves moisture-wicking. This helps keep the sleep surface feeling fresh and hygienic over time.
Natural Rebound Cotton
Cotton breathes naturally and draws moisture away from you as you sleep. The result is a cooler, drier mattress, which hot sleepers will appreciate.
Pocket Spring Core
The heart of the mattress, with 2,000 individually wrapped springs that respond independently to body movement. That independence means better motion isolation, so one restless sleeper is less likely to disturb the other.
All The Layers Again, Reversed
The same layers repeat in reverse order on the underside. This makes the mattress fully double-sided and flippable, which helps it wear evenly for longer.

Key benefits
- Real space for two: At 75cm each for two people sharing, you can both change position freely without ending up in each other's way.
- Motion isolation goes further at this width: Individually wrapped springs already limit partner disturbance, and the wider surface means movement starts further from you in the first place.
- Length for taller sleepers: The 200cm length is a genuine relief if either of you is nearing six foot and used to feet hanging off a shorter mattress.
- Flippable, with help built in: The double-sided design wears evenly when flipped, and the stitched side handles make turning a king size mattress a more manageable two-person job.
- Breathable across a bigger surface: Cotton, wool felt and viscose wick moisture and regulate temperature, which two warm bodies under one duvet will notice on summer nights.
This size suits you if...
You share the bed every night and a double has started to feel cramped, you and your partner keep different hours and want movement on one side to stay on that side, or one of you is tall enough that a standard 190cm length leaves feet dangling. The UK king solves all three without demanding the floor space of a UK super king.
Consider another size if...
Your bedroom is smaller than the 2.7m x 2.9m we suggest as a minimum for a king, or you sleep alone. In either case we'd recommend the UK double instead, which keeps the same double-sided construction in a smaller footprint.

FAQ's
Is the Otty Natural Origin UK king hard to flip?
It takes two people. The mattress is 28cm deep and double-sided, so at king size there's a lot of material to turn. The handles stitched into the viscose cover give you something proper to grip, which helps, but plan to flip and rotate it together rather than attempting it solo.
What room size do I need for the Otty Natural Origin in a UK king?
We suggest a room of at least 2.7m x 2.9m, with around 3.2m x 3.2m feeling comfortable. Measure with wardrobes and drawers in place, as newer master bedrooms can shrink quickly once furniture goes in. If your room falls short, the UK double is the safer choice.
Should I choose the UK king or the UK super king?
The UK king is 30cm narrower than the UK super king, and for most couples it's the sensible middle ground: a clear step up from a double without dominating the room. Go for the UK super king only if your bedroom comfortably exceeds our suggested minimums and you want maximum spread.
Is the UK king long enough for someone over six foot?
At 200cm, the UK king adds 10cm of length over a UK double, which is exactly the upgrade a taller sleeper feels. Someone a little over six foot should fit comfortably. If height is your main reason for sizing up, length matters more than width, and this size delivers it.
