Layer Details
Gel-infused layer
A temperature regulating gel-infused layer tops the mattress and disperses excess body heat, which means you should stay more comfortable if you tend to sleep warm.
Dual-layer pocket spring core
The core has 1000 pocket springs topped with 2000 mini table pocket springs, each in its own cloth sleeve. Because they move independently, you get supportive comfort with less disturbance from a partner.

Key benefits
- Room to get away from a restless partner: You each get 90cm, which means 15cm more per person than the UK king, and that extra distance often does more for broken sleep than any comfort layer.
- Springs that keep movement local: The 1000 pocket springs and 2000 mini springs each sit in their own sleeve, so a child climbing in on one side should barely register on the other.
- Sides you can actually use: A foam encapsulated border supports the edges, which matters on a bed this wide because a small visitor or a dog often ends up sleeping right at the side.
- Help with a crowded, warm bed: More bodies under one duvet means more heat, and the gel-infused top layer is designed to disperse it, which suits families where someone always wakes up too warm.
- Same length as the UK king: Moving up from a UK king adds 30cm of width but no extra length, so the extra floor space you need runs across the room rather than towards the door.
This size suits you if...
You share the bed with a partner whose fidgeting wakes you, and a UK king still feels cramped. It also fits if children or a large dog join you most nights and you want everyone to keep a fair share, and your bedroom comfortably clears 3m x 2.9m.
Consider another size if...
Your bedroom measures less than 3m x 2.9m, or you mostly sleep alone. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m and still gives 75cm each for two sharing.

FAQ's
Is the Optima Gel Pocket 3000 super king big enough for two adults and a child?
For occasional night-time visits, yes. The UK super king gives 90cm each for two adults, so a small child squeezing into the middle still leaves both of you room to turn over. The independently sleeved springs help too, as a wriggling child should cause less disturbance than on an open coil mattress.
Super king vs king Optima Gel Pocket 3000: how much extra space do you get?
The UK super king is 30cm wider than the UK king, and the two are the same length. Shared between two people, that works out at 15cm more each: 90cm per sleeper on the UK super king against 75cm on the UK king. If a restless partner is your main problem, that extra gap is often noticeable.
What size bedroom do I need for a super king Optima Gel Pocket 3000 mattress?
We suggest at least 3m x 2.9m, and around 3.5m x 3.2m tends to feel right once bedside tables and wardrobe doors are open. Before ordering, measure the turn at the top of the stairs and check which way the bedroom door swings, as a 180cm wide mattress can be awkward to manoeuvre.
What bedding fits a UK super king Optima Gel Pocket 3000?
You'll need UK super king sheets and a 260 x 220cm duvet. The mattress is 28cm deep, so choose fitted sheets with deep enough pockets to tuck under properly. Budget for the bedding too, because super king sets usually cost more than the UK king equivalents you may already own.
Is a super king mattress worth it with a dog on the bed?
If a large dog sleeps with you as routine, the UK super king is the size most likely to stop you clinging to the edge. The foam encapsulated border also means the sides feel supportive rather than sagging, so the dog or the person nearest the edge is less likely to roll off.
