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
- The classic couples' size: At 135 x 190cm, the UK double is Britain's long-standing shared size, which means it fits rooms where a UK king would leave you squeezing past the footboard.
- Room for bedside tables: Because the UK double is 15cm narrower than the UK king, most bedrooms can still take a table on both sides, useful if you each want a lamp and a phone charger.
- Natural layers where it matters for two: Two bodies raise the temperature under a duvet, and the breathable plant and animal derived comfort layers help this hybrid run cooler than an all-foam double.
- Medium firm across a shared surface: The medium firm tension supports back and combination sleepers well, so partners with different sleep positions can usually both settle on it.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet fit, and at 30cm deep it still works with widely available deep fitted sheets.
This size suits you if...
You're a couple in a typical UK bedroom where a UK king would dominate the floor, or you sleep alone and want space to spread out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, since the UK double is the size most people expect when they stay.
Consider another size if...
You and your partner both like room to sprawl, or one of you is a restless sleeper. With 67.5cm each for two people sharing, the UK double can feel snug, so we'd recommend the UK king instead if your room allows it.

FAQ's
Is a UK double Simba Natural Hybrid Escape big enough for a couple?
For most couples, yes. The UK double measures 135 x 190cm, giving 67.5cm each for two people sharing, and the medium firm hybrid build keeps movement from travelling too much across the surface. Taller sleepers should note the 190cm length, though: the UK king adds 10cm of length as well as width.
Will a double Natural Hybrid Escape fit my bedroom with bedside tables?
In most rooms, yes. We suggest a minimum of 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. Because the UK double is 15cm narrower than the UK king, it usually leaves enough wall on each side for a table and walking space.
Should I get the Natural Hybrid Escape in a UK double or a UK king?
Choose the UK double if your room is close to the 2.6m x 2.8m minimum we suggest, or if you sleep alone. The UK king is 15cm wider and 10cm longer, so it suits couples with the space to spare, or anyone over about six feet tall who finds 190cm restrictive.
How much space does each person get on a double Natural Hybrid Escape?
Two people sharing a UK double get 67.5cm each. That's the traditional shared allowance and it works for most couples, although if one of you starfishes or you share with a pet who claims a corner, the extra width of the UK king makes a noticeable difference.
Is the UK double Natural Hybrid Escape a good guest room mattress?
It's a sensible guest size, since a 135 x 190cm double comfortably hosts visiting couples as well as solo guests, and double bedding is cheap and easy to find. The natural hybrid build is a premium choice for occasional use, so compare the retailers listed on this page before committing.
