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.

- Fits a typical shared bedroom: At 135 x 190cm (4ft 6in x 6ft 3in), the UK double leaves floor space in rooms where a UK king would crowd the wardrobe or drawers.
- Space for a bedside table each: We suggest at least 2.6m x 2.8m, and around 3m x 3m if you want a bedside table on both sides and a clear path round the bed.
- Support shaped to each of you: The full pocket springs work individually, which means each sleeper's 67.5cm is supported around their own shape rather than their partner's.
- Warmth from two, managed: Two people on a double generate heat, and the graphite in the memory foam helps disperse it, so the surface should feel less stuffy than plain memory foam.
- Easy duvet, one bedding catch: A 200 x 200cm double duvet suits this size, although the 36cm depth means you'll need deep-fitted sheets rather than standard ones.
This size suits you if...
You share the bed every night and your room is around 2.6m x 2.8m or larger, or you sleep alone with a dog or cat who claims a corner, and you would rather sink into a cushioned surface than lie on a firm one.
Consider another size if...
You and your partner both sleep broad or tall and already feel cramped at 67.5cm each. We'd recommend the UK king instead, which gives 75cm each and is 10cm longer; allow at least 2.7m x 2.9m.

Is the Sleepeezee Memory Ultimate 9500 UK double wide enough for two?
For most couples, yes. You each get 67.5cm, and the memory foam cradles each body in its own spot, which helps you settle side by side. If either of you sprawls or sleeps diagonally, the UK king gives 75cm each, so 7.5cm more per person.
Will a Memory Ultimate 9500 double fit in my bedroom with bedside tables?
Allow at least 2.6m x 2.8m for the UK double. If you want a bedside table on both sides plus room to open a wardrobe, around 3m x 3m is the comfortable norm. Measure your room with furniture in place before you buy.
What fitted sheet do I need for a Sleepeezee Memory Ultimate 9500 double?
Look for a deep-fitted double sheet made for a 135 x 190cm mattress. This mattress is 36cm deep, so a standard double sheet may ping off the corners. A 200 x 200cm double duvet sits on top without issue.
Should I size up to a UK king in the Memory Ultimate 9500?
Size up if your room allows it and you want more personal space. The UK king is 15cm wider and 10cm longer than the UK double, and we suggest at least 2.7m x 2.9m for it. In a smaller room, the UK double keeps the space usable.
Is a Memory Ultimate 9500 UK double a good choice for a guest room?
It suits a guest room where couples stay, since the UK double sleeps two in a modest footprint. The medium soft feel tends to please side sleepers and lighter builds, but guests who sleep on their front or prefer a firm bed may find their hips sink a little too far.
