Layer Details
COOLMAX cover
The cover is wrapped in COOLMAX fabric, which wicks away moisture. That should help the surface feel drier and fresher if you tend to sleep warm.
1000 Mini pocket springs
A layer of 1000 mini pocket springs sits under the cover to give delicate, targeted support. It adds a finer level of response close to your body, where you notice shape and pressure most.
Airmesh
A 3D honeycomb comfort layer designed for airflow and breathability. It gives the middle of the mattress an open structure, so heat has more room to escape.
Dual layer of 2000 Mirapocket springs
The core is two layers of Mirapocket springs, 2000 in total. This is the main support system, and because pocket springs move independently, they can respond to your shape rather than pushing back as one unit.
Support pad
A support pad forms the foundation for the layers above. You won't feel it directly, but it gives the springs a steady base to work from.
Breathable perimeter wall
A breathable border material runs around the sides to aid airflow. It helps the mattress release warm air rather than trap it at the edges.

Key benefits
- Space that supports the spring system: Pocket springs compress independently, and 75cm each for two people sharing means less overlap in the first place, so a restless partner registers less.
- A real step up from a double: The UK king is 15cm wider than the UK double, which you feel as elbow room rather than a number on a spec sheet.
- Length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, a genuine relief if one of you is approaching six foot.
- Suits mismatched schedules: If one of you gets up hours before the other, independent springs plus the wider footprint help the early riser slip out with less disturbance.
- Room to lose to a pet: A dog who claims the foot of the bed every night takes a smaller share of a UK king than of anything narrower.
This size suits you if...
You share the bed every night and have found a double leaves you nudging each other awake, one of you keeps earlier hours than the other, or one of you is tall enough that a standard 190cm mattress leaves feet at the edge. The 200cm length and 75cm each for two people sharing address both problems at once.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m and still gives a couple pocket spring support.

FAQ's
Is a UK king big enough for a couple on this Silentnight mattress?
Yes, comfortably for most couples. The UK king measures 150 x 200cm, giving 75cm each for two people sharing, and the pocket springs respond to each sleeper separately. If you want still more personal space, the UK super king is 30cm wider than the UK king and the two are the same length.
Will the UK king suit a tall sleeper?
This is the size where length improves. The UK king is 10cm longer than the UK double at 200cm, which usually solves the feet-off-the-end problem for anyone approaching six foot. If height is your only concern, the UK king delivers the fix without demanding the floor space a UK super king does.
What room size do I need for the Silentnight Eco Comfort Airmesh in a UK king?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables are in. Many new build master bedrooms look generous empty but tighten quickly with furniture, so measure the usable floor rather than the whole room before committing.
Does a UK king reduce partner disturbance on a pocket spring mattress?
It helps on two fronts. The pocket springs move independently, so a turn on one side transfers less across the bed, and the 150cm width simply puts more distance between you. Couples on different schedules, where one leaves early, tend to notice the difference most.
Where can I buy this mattress in a UK king?
Availability for this model is more limited than for widely stocked mattresses, so compare the retailers listed on this page. The prices shown here are updated as retailers change them, which is the safest way to check what the UK king costs today.
