Layer Details
Cover
A soft woven viscose cover creates a silky smooth finish. It's the first thing you'll feel, and it sets a gentle tone for the layers beneath.
Pillow top
An additional comfort layer filled with natural alpaca wool, which means a more luxurious feel underneath you. The alpaca also helps with temperature regulation, useful if you tend to overheat at night.
Latex
Latex is incredibly durable and returns to its shape quickly, offering superior pressure relief. In practice, that means less of a sinking feeling and easier movement when you change position.
Wool
A natural insulator with strong temperature regulating properties. It works alongside the alpaca layer to keep the sleep surface closer to a comfortable temperature year round.
Pocket Springs and Mini Pocket Springs
4500 traditional pocket springs are combined with 2500 mini pocket springs, each individually cased. This provides personalised support along your body and reduces motion transfer, so a restless partner is less noticeable.

Key benefits
- Room to spread out: At 75cm each for two sharing, you gain 7.5cm of personal space over a UK double, enough to stop elbows meeting in the night.
- Less disturbance from early risers: Individually cased springs paired with the wider UK king surface mean a partner's movements travel less, which helps when one of you leaves for work long before the other.
- Length for taller sleepers: The UK king runs to 200cm, or 6ft 6in, so a tall partner is less likely to find their feet hanging over the end.
- Space without a super king's footprint: You get noticeably more room than a UK double, while the UK king needs a smaller bedroom than the 3m x 2.9m we suggest for a UK super king.
- Easier for changing positions: Latex returns to shape quickly, and the extra width on a UK king leaves room for a pregnancy pillow without pushing your partner towards the edge.
This size suits you if...
You share the bed every night and want more room each than a UK double gives, or one of you is tall enough to find a 190cm bed a little short. It also suits couples on different schedules who want to be disturbed less.
Consider another size if...
Your bedroom is smaller than our suggested minimum of 2.7m x 2.9m. We'd recommend the UK double instead, for which we suggest at least 2.6m x 2.8m.

FAQ's
Is the Sleepeezee Centurial 03 UK king big enough for two people?
Yes, for most couples. The UK king gives 75cm each for two sharing, which is 7.5cm more each than a UK double. That is enough for a noticeable gain in personal space, although couples who both sleep spread out, or who share with a dog, may still want the UK super king.
Will I feel my partner move on a Centurial 03 in UK king?
Less than you would on a narrower bed. The Centurial 03 pairs 4500 pocket springs with 2500 mini springs, each individually cased, so movement stays more local. On a UK king you also have 75cm each, which puts a little more distance between you and a partner who gets up hours earlier.
Is the UK king Centurial 03 long enough for a tall partner?
It is 200cm long, or 6ft 6in, which is 10cm longer than a UK double. For a tall sleeper, that extra length is often the real reason to upgrade. The UK super king is the same length, so sizing up adds width but no extra room for your feet.
Should I choose the Centurial 03 in UK king or UK super king?
Choose the UK king if space in your bedroom is limited. It is 30cm narrower than the UK super king and gives 15cm less each, but we suggest at least 2.7m x 2.9m for a UK king against 3m x 2.9m for a UK super king. If your room can take it and you both want more room, the UK super king makes sense.
Will a UK king Centurial 03 fit in a new build master bedroom?
Measure after the wardrobes are in, because new build rooms often feel smaller once furnished. We suggest allowing at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m comfortable. At 35.5cm deep, the Centurial 03 also sits high on its base, so check your bedside tables still line up.
