Layer Details
- Knitted cover. A knitted cover tops the mattress, adding a final soft layer against you.
- Microquilted layer. A micro-quilted finish gives the surface a smooth, soft feel from the first night.
- Soft White Fibres. Soft synthetic fillings sit near the top to create a cosy feel. This is where much of the plushness comes from.
- Memory Foam. Memory foam cradles your shape for a cushioned feel, which means pressure is spread rather than concentrated. It's made with graphite to help disperse body heat.
- Mini Pocket Springs. Small, individually cased springs add a responsive comfort layer with soothing pressure relief.
- Pocket Springs. The main support layer: springs encased in individual cloth pockets that adapt to movement, distributing support to each part of your body.

- Distance from a restless partner: With 90cm each, a partner who turns all night is simply further away, which helps more than any comfort layer when the fidgeting is genuine.
- Room when children climb in: A 6ft by 6ft 6in surface means a small visitor in the middle still leaves both adults a usable share, rather than one of you clinging to the edge.
- Space for dogs as routine: If a large dog sleeps on the bed most nights, the extra width over the UK king gives it somewhere to settle that isn't across your legs.
- A soft surface spread wide: The medium soft, sink-in feel suits lighter side sleepers, and at this width each of you gets that plush surface without being drawn towards the other.
- Proportion in a large room: In a period property or a generous master bedroom, a UK king can look undersized, while the UK super king fills the space the way the room expects.
This size suits you if...
You share the bed with a genuinely restless partner and want real distance between you, or children and pets regularly end up in with you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m, or a sloping loft ceiling leaves no wall long enough. We'd recommend the UK king instead, and we suggest at least 2.7m x 2.9m for it.

How much more space does the Sleepeezee Memory Ultimate 9500 UK super king give than the UK king?
The UK super king is 30cm wider than the UK king, and both are the same length. For two people sharing, that works out at 15cm more each. It sounds modest, but if one of you moves a lot in the night, that extra gap is often what stops you waking each other.
Is the Memory Ultimate 9500 UK super king big enough for two adults and a child?
For occasional night-time visits, yes. You each start with 90cm, so a child in the middle still leaves both adults a fair share. Bear in mind the soft, sink-in surface means bodies settle into the mattress rather than sitting on top, so a small visitor tends to stay where they land.
What sheets fit a Sleepeezee Memory Ultimate 9500 super king?
You'll need a deep-fitted super king sheet, because this mattress is 36cm tall and standard fitted sheets may not grip the corners. For the top of the bed, a 260 x 220cm duvet is the usual choice. Deep-fitted bedding at this size costs more than standard sets, so include it in your budget.
Will the Memory Ultimate 9500 in a UK super king fit a 3m bedroom?
We suggest allowing at least 3m x 2.9m, with around 3.5m x 3.2m feeling right. At the minimum it fits, but check that the door can swing open fully and that you can walk around both sides. In a loft conversion, the ceiling slope usually decides which wall the bed can go against.
Should a couple choose the UK super king or UK double Memory Ultimate 9500?
The UK super king is 45cm wider and 10cm longer than the UK double. The UK double gives 67.5cm each for two sharing, so the UK super king gives 22.5cm more each. If you both sleep soundly and space is tight, the UK double works, though we suggest at least 2.6m x 2.8m for it.
