- Proper space for two: With 75cm each for two people sharing, you can spread out a little rather than negotiating an invisible centre line every night.
- Springs that keep disturbance to your side: Individually pocketed springs compress under you alone, which means an early riser slipping out at 6am is far less likely to wake the other.
- Length for taller sleepers: At 200cm long, the UK king is 10cm longer than the UK double, a genuine relief if one of you is approaching six foot.
- A clear step up from a double: The UK king is 15cm wider than the UK double, a difference you feel every night rather than a figure on a spec sheet.
- A medium feel that suits shared beds: The medium tension works for most couples, particularly if one of you sleeps on your side and the other on your back.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially if one of you gets up hours before the other and you want their movement to stay on their side. It's also a sensible choice if one partner is tall, since the extra 10cm of length over a UK double stops feet hanging off the end. If the dog has a standing invitation too, the extra width helps.
Consider another size if...
Your room falls short of the 2.7m x 2.9m we suggest, or you sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m and still gives a solo sleeper plenty of space.

Is the Harrison Spinks Ultra Plush 4500 in a UK king good for couples?
Yes, and it's arguably the size this mattress makes most sense in. Two people sharing get 75cm each, and the pocket springs respond to each of you separately, so one partner shifting or getting up early transfers less movement across the bed. The medium feel suits most couples, although anyone wanting a firm surface should look elsewhere in the range.
How much bigger is the UK king Ultra Plush 4500 than the double?
The UK king is 15cm wider than the UK double and 10cm longer, at 150 x 200cm against 135 x 190cm. The width is what couples notice first, but the length is the quieter win: if either of you is tall, that extra 10cm keeps feet on the mattress rather than over the edge.
What room size do I need for the Ultra Plush 4500 in a UK king?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. That's our own guidance rather than a Harrison Spinks figure. New build master bedrooms can be tighter than they first appear once fitted wardrobes go in, so measure the clear floor space, and check you can still open drawers and walk down both sides.
Should I pick the UK king or super king in this mattress?
The UK king is the middle ground: real space for two without the room a UK super king demands. The UK super king is 30cm wider at the same length, and we suggest at least 3m x 2.9m for it. If your room clears that comfortably and you want maximum separation, size up; otherwise the UK king is the safer buy.
Is a UK king long enough if my partner is over six foot?
At 200cm, or 6ft 6in, the UK king gives a six-footer roughly half a foot of clearance, which is comfortable for most tall sleepers. That's 10cm more length than the UK double, and it's often the length rather than the width that makes the upgrade feel right. Sizing up to the UK super king adds width only, since both sizes are the same length.
