Layer Details
- Hand-Stitched Tufted Cover. Handmade in the UK from thick viscose, with handles on the sides. That means rotating and flipping this heavy, double-sided mattress is far less of a struggle.
- Luxurious Wool, Silk & Cashmere. A blend of wool, silk and cashmere sits just beneath the cover. These fibres breathe and regulate temperature naturally, so the sleep surface feels soft without trapping heat.
- Natural Rebound Cotton. A layer of naturally breathable cotton that wicks moisture away. This helps keep the mattress cool and dry over time.
- 1750 Micro Pocket Springs. Smaller, high-density springs that respond to finer pressure points than a standard spring unit can. You'll feel this as gentler cushioning at shoulders and hips, with less partner disturbance.
- Natural Rebound Cotton. A second cotton layer, again breathable and moisture-wicking. It keeps airflow moving between the two spring systems.
- Core Pocket Spring Unit. Individually wrapped springs that adapt to your body shape, which means proper spinal alignment and reduced pressure points. This is the mattress's main support engine.
- All The Layers Again - Reversed. The whole construction is mirrored on the other side, making the mattress fully flippable. Flipping spreads wear evenly and extends the mattress's lifespan.

- 90cm each, every night: Two people sharing get 90cm each, so you can stretch out fully without negotiating over the middle of the bed.
- Distance plus spring isolation: The 1,750 micro pocket springs already dampen a partner's movement, and at this width you're simply too far away to feel most of it anyway.
- Space for night-time visitors: Children who appear at 3am, or a large dog with a standing invitation, fit here without anyone ending up clinging to an edge.
- Fills a large master properly: In a period property or generous new build master, a UK king can look lost against the wall, and the 180cm width sits in proportion.
- Handles make the flip manageable: A double-sided 28cm mattress at this size is genuinely heavy, but the side handles make flipping a realistic two-person job rather than an ordeal.
This size suits you if...
You share every night and want the maximum standard width UK retailers stock, your partner is restless enough that isolation alone doesn't cut it, or children and pets regularly join you and everyone still needs a fair share. Your bedroom should measure at least 3m x 2.9m, and ideally more, so the bed doesn't dominate the room.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m minimum, or you'd struggle to flip a mattress this heavy at this width. We'd recommend the UK king instead: 30cm narrower, and far easier to turn.

How big is the Otty Natural Evolve in a UK super king?
It measures 180 x 200cm, or 6ft x 6ft 6in, with the same 28cm depth as every other size. That's the widest size stocked as standard in the UK, and 30cm wider than the UK king, so check door swings and landing turns before you order.
Is the Otty Natural Evolve super king good for couples with a restless partner?
It's a strong pairing. The 90cm each for two people sharing puts real distance between you, and the micro pocket springs reduce motion transfer on top of that. If one of you fidgets or keeps odd hours, this size does more for undisturbed sleep than any comfort layer could.
Can two adults and a child fit on a super king Otty Natural Evolve?
Yes, within reason. At 180cm wide, a small child wandering in at night can settle between you without pushing either adult to the edge, and the medium-firm pocket spring support holds up across the full surface. The same goes for a dog who treats the bed as routine.
Is the Otty Natural Evolve hard to flip in a super king?
It's the hardest size of this mattress to flip, no way around that: 28cm deep, double-sided and 180cm wide adds up to a heavy lift. The side handles help, and it's a two-person job. If regular flipping sounds unrealistic, consider a smaller size or a one-sided design.
