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
- Space for two to sleep, not negotiate: At 75cm each for two people sharing, you can both stretch out without elbowing each other, which matters most when one of you is a restless sleeper.
- 15cm wider than a UK double: That extra width over the UK double sounds small on paper but changes how the bed feels every single night you share it.
- Length for taller sleepers: At 200cm long, anyone approaching or over six foot gets their feet on the mattress rather than hanging off the end.
- Springs help with different schedules: The sprung hybrid build, combined with the wider footprint, means an early riser can slip out with less of the movement carrying across the bed.
- Breathability across a bigger bed: Two people sharing means twice the body heat, and the natural comfort layers breathe better than synthetic foam, a real advantage at this size.
This size suits you if...
You share the bed every night and have outgrown a UK double, one of you is tall enough to need the 200cm length, or your sleep gets broken by a partner who turns over or gets up at a different hour. It also suits couples whose dog has claimed a corner of the bed and shows no sign of giving it back.
Consider another size if...
Your bedroom is smaller than the 2.7m x 2.9m we'd suggest as a minimum, or you sleep alone. In either case the UK double of this mattress would suit you better and take up noticeably less floor space.

FAQ's
Is the Simba Natural Hybrid Escape UK king big enough for a couple?
Yes, comfortably for most. At 150cm across, it gives 75cm each for two people sharing, enough to change position without disturbing your partner. If you routinely share with a pet or a small child as well, the UK super king adds another 30cm of width and may be the better fit.
Will a UK king fit in a new build master bedroom?
Often, but measure first. New build masters can shrink once wardrobes and bedside tables go in, so allow at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m feeling comfortable. That's our guidance rather than Simba's, and it assumes you want to walk round both sides of the bed.
Is the UK king long enough for someone over six foot?
Yes. The UK king runs to 200cm long, and for many taller sleepers that length is the real reason to size up from a UK double, which is 10cm shorter. Combined with the medium firm tension, a taller back sleeper should feel supported right to the end of the mattress.
Does the king size help if my partner gets up earlier than me?
It helps more than you might expect. The extra width means the person leaving early can get out from their own side without climbing over or jostling you, and the sprung hybrid construction keeps most of that movement local rather than rolling across the whole mattress.
Should I choose the UK king or the UK super king in this mattress?
The UK king suits most couples: generous space without dominating the room. The UK super king is 30cm wider, worth it if you have the floor space and share with children or a dog, but it demands a larger bedroom and bigger bedding. Compare the retailers listed on this page for both sizes before deciding.
