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
- Motion isolation with room to spare: The individually wrapped springs respond to each sleeper separately, and at 90cm each for two people sharing, a fidgety partner is doubly easy to sleep through.
- Space for the whole household: When children pad in at 3am, or a large dog treats the bed as routine, the 180cm width means everyone still gets a genuine share.
- A frame that fills a big room: In a period property or a large master, a UK king can look undersized; the UK super king sits in proportion with the space.
- Flippable, so the wear spreads: Both faces carry the same layers, which means you can flip as well as rotate this size and share the load across a surface this large.
- Natural materials that breathe: Wool felt, cotton and viscose wick moisture across the full 6ft width, helpful when two adults, and sometimes more, are warming the same bed.
This size suits you if...
You share every night and a UK king still feels like a compromise, perhaps because your partner turns constantly and you want distance as well as motion isolation. Or your household regularly grows overnight, with young children or a dog joining you, and you want everyone to keep a proper share of the bed. It also fits if your master bedroom is large enough that a smaller size would look lost.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest as a minimum for this size, or you'd struggle to flip a mattress this heavy regularly. We'd recommend the UK king instead: 30cm narrower, and far easier to turn.

FAQ's
Is the Otty Natural Origin super king hard to flip?
It's the most demanding size of this mattress to turn. At 180 x 200cm and 28cm deep, with mirrored layers on both faces, this is firmly a two-person job. The handles stitched into the viscose cover help, but plan on flipping it together rather than wrestling it alone.
What room size do I need for a super king Otty Natural Origin?
We suggest a minimum of 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once you add bedside tables and walking space. In a loft conversion, check the ceiling slope too, since a bed this wide has fewer walls it can sit against.
Is the super king worth it over the UK king for a restless partner?
Often, yes. The pocket springs already absorb movement, but the UK super king is 30cm wider than the UK king, giving you 90cm each for two people sharing. That extra distance does what no comfort layer can: it puts the fidgeting further away from you.
Is this size good for co-sleeping with children or pets?
It's the strongest case for going this big. At 180cm wide, a child wandering in at night, or a large dog with established habits, can join you without pushing either adult to the edge. The independent springs also mean their movements are less likely to wake you.
Where can I buy the Otty Natural Origin in a UK super king?
Stock varies by size, so the simplest route is to compare the retailers listed on this page. The prices shown here are updated as retailers change them, which matters at this size, where bedding and the mattress itself are typically stocked by fewer shops than the UK double or UK king.
