Layer Details
Cover
A knitted micro quilted cover, which means the top surface has a soft, slightly cushioned texture stitched into it. It adds a touch of surface comfort without a separate pillow top.
Fillings
100% polyester fibre fillings sit between you and the springs. These give a simple, breathable comfort layer, though they won't contour to your body the way memory foam would.
Springs
1000 individual pocket springs form the support core, part of Silentnight's Mirapocket system. Each spring is sewn into its own fabric pocket, so it responds to pressure independently and reduces the ripple effect when someone else moves.

Key benefits
- Space to sleep apart, together: At 75cm each for two people sharing, you can both turn over without negotiating, which matters more on a springy pocket sprung feel than a contouring one.
- Less disturbance across a wider bed: The 1000 individual pocket springs move independently, and the UK king's extra width puts more of those springs between you and a restless partner.
- Length for taller sleepers: The UK king is 10cm longer than the UK Double, a real difference if one of you is approaching six foot and tired of feet at the edge.
- A budget-friendly way to size up: Because the fillings are simple polyester fibre, the step up to a UK king stays affordable compared with upgrading in a plusher hybrid range.
- Breathable at a bigger size: Polyester fibre fillings run cooler than deep foam layers, so a larger shared bed doesn't turn into a warmer one.
This size suits you if...
You share the bed every night and a double no longer gives you both enough room, or one of you gets up hours before the other and the ripple of movement keeps waking the sleeper left behind. It also suits you if one partner is tall enough to want the 200cm length, or the dog has quietly claimed a strip of the mattress and you'd like your share back.
Consider another size if...
Your bedroom is smaller than the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. In either case we'd recommend the UK double instead, which needs at least 2.6m x 2.8m of room.

FAQ's
Is the Silentnight Pocket Essentials 1000 in a UK king good for couples?
Yes, provided you both suit its medium firm feel. The pocket springs respond to each of you separately, so early alarms and late nights disturb the other person less, and 75cm each for two people sharing means you're not sleeping in each other's space. Lightweight side sleepers may still find it a little firm at the shoulder.
What room size do I need for the Pocket Essentials 1000 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 go in. New build master bedrooms can be tighter than they look on the plan, so measure with the furniture in place before committing to a UK king.
Is the UK king Pocket Essentials 1000 long enough for tall sleepers?
At 200cm, the UK king is 10cm longer than the UK Double, which is often the difference between feet hanging over the edge and lying flat comfortably. If one of you is over six foot, that extra length is arguably a bigger upgrade than the width.
How big is the Pocket Essentials 1000 UK king in feet?
It measures 5ft x 6ft 6in, or 150 x 200cm. That's 15cm wider and 10cm longer than the UK Double, so check your bed frame is a genuine UK king before ordering, as the mattress won't sit properly on a double base.
Should I get the Pocket Essentials 1000 in a UK king or a UK super king?
The UK king is 30cm narrower than the UK Super King, and the two are the same length. If your room meets the 3m x 2.9m we suggest for the UK Super King and you want maximum personal space, size up. Otherwise the UK king gives most couples enough room without dominating the bedroom. Compare the retailers listed on this page for both.
