Key benefits

Key Benefits of the Harrison Spinks Jade 10000 Pocket King Size Mattress (Firmer Feel)

  • 75cm each for two sharing: Each of you gets 75cm of width, which means room to change position without negotiating for territory in the night.
  • Pocket springs limit partner disturbance: Each spring compresses independently, so if one of you gets up hours before the other, less of that movement travels across the bed.
  • 200cm of length for taller sleepers: The UK king is 10cm longer than the UK double, which means anyone approaching six foot stops sleeping with their feet at the edge.
  • Firm support across the full width: A firm pocket spring surface holds you on top of the mattress, so the extra width is all usable rather than lost to sinkage in the middle.
  • Fits most main bedrooms: We suggest allowing at least 2.7m x 2.9m, which most UK master bedrooms can manage without giving up wardrobe space.

Who should buy the Harrison Spinks Jade 10000 Pocket King Size Mattress (Firmer Feel)?

This size suits you if...

You share the bed every night and a double leaves you brushing elbows, or one of you keeps different hours and the other feels every exit. It also suits you if either sleeper is approaching six foot, since the 200cm length is a genuine relief, or if a dog has quietly claimed a share of the mattress and 75cm each no longer stretches far enough on a double.

Consider another size if...

Your bedroom falls short of 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, allowing at least 2.6m x 2.8m for that size.

FAQ's

Frequently Asked Questions About the UK King

What room size do I need for the Jade 10000 in a UK king?

We suggest a room of at least 2.7m x 2.9m, with around 3.2m x 3.2m feeling genuinely comfortable. That allows walking space on both sides and the door to open cleanly. This is our guidance rather than the manufacturer's, so measure your room with wardrobes and drawers in mind, particularly in a new build master that shrinks once furniture goes in.

Is the UK king Jade 10000 Firmer Feel good for couples?

Yes, and arguably better than most sizes of this mattress. You get 75cm of width each, and because the firm surface keeps you on top rather than sinking in, that width stays usable. The pocket springs also isolate movement, so a partner leaving early for work sends less disturbance across to your side than an open coil design would.

Should I get the Jade 10000 in a UK king or a UK super king?

The UK super king is 30cm wider than the UK king, with the same 200cm length, so the choice comes down to width and room size. We suggest at least 3m x 2.9m for the UK super king, against 2.7m x 2.9m for the UK king. If your room takes it and you want maximum personal space, size up; otherwise the UK king suits most couples.

How big is the Harrison Spinks Jade 10000 in a UK king?

It measures 150 x 200cm, which is 5ft x 6ft 6in. That is 15cm wider and 10cm longer than the UK double, so the upgrade is felt in both directions: more elbow room for two sharers and extra length for a taller sleeper whose feet currently reach the end of the bed.
