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.

- Fits where space is tight: At 90cm wide it leaves floor room for a desk, wardrobe or toy storage, which matters in a child's room or a loft conversion with a narrow footprint.
- The easiest size to flip: This mattress needs regular flipping, and the UK single is the lightest version of it, so one adult with the side handles can manage the job alone.
- Natural fillings for growing sleepers: Wool, cotton and cashmere regulate temperature naturally, a genuine plus for teenagers who run warm at night.
- Guest room friendly: In a spare room that doubles as an office, a single along one wall keeps the desk usable while giving guests proper pocket-sprung support rather than a token bed.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked of any size, so you won't hunt for fitted sheets deep enough for the 28cm profile.
This size suits you if...
You sleep alone and want natural fillings in a bed that fits a smaller room, you're buying for a child or teenager who has outgrown a starter bed and needs a mattress that will last through growth spurts, or you're furnishing a spare room, student flat or study that doubles as guest space and a wider mattress would crowd it.
Consider another size if...
You're an adult who moves around at night and finds 90cm restrictive, or two of you will ever share it. We'd recommend the UK double instead, which is 45cm wider and the same length.

Will the Otty Natural Evolve UK single fit a bunk bed?
Probably not. At 28cm deep it's thicker than most bunk, cabin and mid-sleeper frames allow, because safety guidance requires the guard rail to sit well above the mattress surface. Measure from the base to the top of the rail before buying, and if the gap is too small, choose a shallower mattress for raised frames.
What size room do I need for a UK single Otty Natural Evolve?
We suggest allowing at least 2.1m x 2.8m of floor space, which gives you room to walk around the bed and open drawers or wardrobe doors. That's our guidance rather than Otty's. In a child's room, the 90cm width leaves useful space for a desk and toy storage alongside the bed.
Is the UK single Otty Natural Evolve big enough for an adult?
For one adult, yes, provided you're comfortable with the space. It measures 90 x 190cm, so most adults fit the length with room to spare, and the medium-firm pocket-sprung support works the same as in the larger sizes. Restless sleepers or anyone over about 6ft may prefer sizing up.
Can one person flip the single size on their own?
Yes, and this is the size where flipping is least of a chore. The mattress is double-sided and needs turning to spread wear evenly, and while the 28cm build is heavy for its class, the single is the smallest version and has handles stitched into the sides to give you grip.
How much smaller is the single than the small double?
The UK single is 30cm narrower than the UK small double, and the two are the same length at 190cm. That extra width is the difference between a one-person bed and a roomier solo bed, so if the bedroom can take 120cm across, the UK small double gives a lone adult noticeably more sprawling room.
