Layer Details
- Knitted cover. A soft knitted finish that adds a touch of cosiness and warmth. It also helps airflow, which means less heat building up around you overnight.
- Soft White Fibres. Soft synthetic fillings that give the surface its cosy feel while staying durable and resilient. They're designed to hold their shape rather than flatten quickly.
- Dense polyester fibres. Tightly packed fibres that provide secure cushioning without letting you sink in too deep. This is where the extra firm character really comes through.
- Miracoil Springs. Silentnight's open coil system with separate support zones, which means your weight is spread evenly and your spine is supported where it needs it most. The zoning helps relieve pressure while you sleep.

- More room each: You get 75cm each for two people sharing, which is 7.5cm more per person than the UK double and enough to stop elbows meeting at night.
- Length for taller partners: At 200cm long, the UK king adds 10cm over the UK double, which means a partner over six foot is less likely to have their feet hanging off the end.
- Distance from a partner's movement: The extra 15cm of width over the UK double puts a little more space between you, helpful when one of you gets up hours before the other.
- Firm across the full width: Miracoil's zoned open coil springs support your hips and keep your spine level on both sides, so neither partner rolls into a softer middle.
- Room to shift and prop: During pregnancy or recovery, the UK king leaves space for extra pillows without squeezing your partner, although lighter side sleepers may find the extra firm surface a little unyielding.
This size suits you if...
You share the bed every night and keep bumping into each other on a UK double, one of you is over six foot and needs the extra length, or you and your partner keep different hours and want a bit more distance when one of you gets up early.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once wardrobes are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

Is the Silentnight Vilana UK king long enough for someone over six foot?
The UK king is 200cm long, 10cm longer than the UK double, the UK small double and the UK single in this range. For a partner around or above six foot, that extra length is often the real reason to size up, since it gives room at the foot end as well as the head.
How much space does each person get on a Silentnight Vilana king size?
Two people sharing the UK king get 75cm each. The UK double gives 67.5cm each, so the UK king adds 7.5cm per person. That sounds small on paper, but across a whole night it can mean fewer knocks from a partner who turns over or spreads out.
Will a UK king Vilana fit in a new build master bedroom?
We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m comfortable. New build master bedrooms can feel tighter once fitted wardrobes go in, so measure the floor space that is actually free. If you fall short, the UK double needs at least 2.6m x 2.8m.
Vilana UK king or UK double for couples on different shift patterns?
If one of you leaves hours before the other, the UK king's extra 15cm of width puts a little more space between you when someone gets up. The firm Miracoil base also resists sinkage, which means less of a dip for the sleeping partner to roll into.
