Layer Details
Silky viscose cover
A soft, plant-derived viscose cover with invisible tufting, which keeps the surface smooth. You get a sleek feel under you without the dips and ridges that visible tufting can leave.
Hampshire wool cushioning layer
A quilted layer of soft, springy Hampshire wool, designed for cushioned comfort and cooling breathability. It gives you some softness on top and helps air move, which should suit you if you tend to run warm.
British wool comfort layer
A second quilted layer of soft British wool that adds to the comfort and breathability above the springs. It means the cushioning comes from natural wool rather than foam.
Aerocoil spring support layer
Up to 1,900 conical Aerocoil micro springs in a king size, designed to give responsive pressure relief while limiting motion transfer. You get a bit of give where your body presses in, and a partner's movement should travel less.
British wool stability layer
An extra layer of wool sits between the two spring layers to keep air flowing and support durability. You won't feel it directly, but it helps the inside of the mattress breathe.
Aerocoil spring base layer
A further 1,900 patented, conical Aerocoil micro springs towards the base, which work to give responsive, accurate support. This second spring layer helps the mattress hold you steadily beneath the softer upper layers.
British wool support layer
A last layer of British wool above the sprung base, designed to help with stability and keep the mattress breathable. It acts as a natural buffer between the springs and the layers above.
CoreMax sprung base
Up to 1,000 high carbon steel springs in a king size, arranged in seven support zones with a reinforced frame. The zoning is meant to keep your body aligned, and the reinforced frame should help limit that roll-off feeling at the edges.

Key benefits
- 90cm each, every night: Two people sharing get 90cm each, which means a partner who turns over frequently is far enough away that you'll rarely feel it.
- Springs plus space for restless sleepers: The sprung hybrid build settles quickly after movement, and at 180cm wide there's enough distance that most movement never reaches you anyway.
- Room for the whole household: If children or a large dog end up in the bed most nights, a super king means everyone still gets a fair share of the mattress.
- Natural materials across a bigger surface: Breathable plant and animal derived comfort layers matter more with two warm bodies sharing, helping the bed stay cooler than a synthetic all-foam equivalent.
- Fills a large master properly: In a big period bedroom or a generous new build master, a UK king can look undersized; the 6ft x 6ft 6in footprint sits in proportion.
This size suits you if...
You share the bed every night and one of you is a light sleeper, a restless sleeper, or both. It also fits if children or pets regularly join you before morning, or if your master bedroom is large enough that a UK king would leave the room feeling half-furnished. We suggest allowing at least 3m x 2.9m of floor space, with around 3.5m x 3.2m feeling comfortable.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest as a minimum, or you'd struggle to get a 180cm mattress round your landing. We'd recommend the UK king instead, which is 30cm narrower and far easier to place.

FAQ's
Is a super king too big for my bedroom?
It depends on the room, not the mattress. We suggest allowing at least 3m x 2.9m for the 180 x 200cm footprint, and around 3.5m x 3.2m feels right, leaving space to walk round both sides and open wardrobe doors. Measure with the door swing included; that's the check that usually bites at this size.
Is the Simba Natural Hybrid Escape super king good for couples?
Yes, and space is the main reason. Two people sharing get 90cm each, so a partner who shifts position through the night is genuinely easier to ignore. The medium firm tension suits back and combination sleepers well, although a lightweight side sleeper may find it slightly too firm at the shoulder regardless of size.
How much wider is the Simba Natural Hybrid Escape super king than the king?
The UK super king is 30cm wider than the UK king, at 180cm against 150cm, and both are 200cm long. That extra 30cm is the difference between sharing comfortably as a couple and sharing comfortably when a child or dog joins you at 3am.
What bedding do I need for a super king Simba Natural Hybrid Escape?
Super king fitted sheets sized for 180 x 200cm, and we'd suggest a 260 x 220cm duvet so both sleepers get proper coverage. The mattress is 30cm deep, so standard deep fitted sheets will still work. Bedding at this size is a little pricier and stocked by fewer shops, so factor that into the budget.
Will a super king mattress get up the stairs?
At 180cm wide it's the trickiest standard size to move, so measure your staircase, any landing turns and the bedroom doorway before ordering. Hybrids with springs can't be folded the way an all-foam mattress sometimes can, so a tight Victorian staircase or an awkward loft conversion deserves a proper check first.
