Layer Details
Plush pillow top
A plush layer stitched onto the surface of the mattress for extra comfort and support. It softens the feel of the top without changing the firm rating.
Mirapocket spring core
1000 Mirapocket springs, each in its own fabric pocket and reacting independently. That means the mattress follows your movements and helps limit disturbance to a partner.
Protective base layer
A layer under the springs that spreads their pressure across the whole surface. It's there to help the mattress last longer.

Key benefits
- More room before you touch: At 150cm wide you each get 75cm, which means on a firm surface, where you lie on top rather than sinking in, there's slightly more space before you meet your partner.
- Calmer early starts: The pocketed springs react individually, so if one of you gets up hours before the other, the movement should travel less, and the extra width puts a little more distance between you.
- Length for taller sleepers: At 200cm, or 6ft 6in, the UK king is 10cm longer than the UK double, and for anyone over six foot that length matters more than the width.
- Fits where a super king won't: We suggest allowing at least 2.7m x 2.9m for a UK king, compared with 3m x 2.9m for the UK super king, so it suits more modest main bedrooms.
- Easy to dress: Standard king sheets fit, and a 230 x 220cm king duvet gives enough overhang that neither of you ends up pulling the covers across.
This size suits you if...
You share the bed every night and have started bumping elbows in a UK double, or one of you is over six foot and the 190cm length of the smaller sizes leaves your feet at the edge.
Consider another size if...
Your bedroom is smaller than 2.7m x 2.9m once furniture is in. In that case we'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Silentnight 1000 Pillow Top Pocket Ortho king size big enough for two adults?
For most couples, yes. The UK king gives 75cm each, 7.5cm more each than the UK double. If you both sprawl or a dog joins you most nights, the UK super king gives 90cm each, though we suggest at least 3m x 2.9m of floor space for it.
What size bedroom do I need for a UK king Silentnight 1000 Pillow Top Pocket Ortho?
Allow at least 2.7m x 2.9m, with 3.2m x 3.2m giving comfortable space to walk round both sides. New build main bedrooms often feel smaller once fitted wardrobes are in, so measure the clear floor first, then compare the retailers listed on this page.
Is a UK king mattress long enough if I'm over six foot?
At 200cm, or 6ft 6in, the UK king is 10cm longer than the UK double, which gives a tall sleeper real room at the foot. The UK super king is the same length, so if length is your only concern, there's no need to size up beyond the UK king.
Will my partner feel me move on the king size Silentnight 1000 Pillow Top?
Less than on a smaller size, most likely. The 1000 springs sit in separate pockets and respond individually, and in a UK king you each have 75cm, so there's more mattress between you. It is rated firm, so you'll lie on top of the pillow top rather than sinking into it.
What bedding fits a Silentnight 1000 Pillow Top Pocket Ortho in UK king?
Use UK king sheets for the 150 x 200cm surface, and choose fitted sheets with pockets deep enough for the 27cm depth so the corners stay put. A 230 x 220cm king duvet fits well and leaves enough width for two people to share without a nightly tug of war.
