Layer Details
Soft knitted cover
A soft knitted cover forms the sleep surface. It gives a gentle, slightly cushioned first touch.
Soft polyester comfort layer
A soft polyester comfort layer sits just beneath the cover, which means immediate surface softness before you reach the firmer materials below.
High density polyester support layer
A high density polyester layer adds a firmer transition. It stops you sinking straight through to the foam and springs.
Double depth Graphite memory foam
A double depth layer of graphite memory foam that draws heat away from your body. You get pressure relief around hips and shoulders with less of the warmth ordinary memory foam can trap.
2500 mini comfort springs
A layer of 2,500 mini comfort springs adds responsive, fine-tuned cushioning. These smaller springs react to smaller movements, so the surface feels adaptive rather than flat.
2000 traditional pocketed springs
The base is 2,000 traditional pocketed springs with full foam encapsulation. Each spring moves independently to reduce partner disturbance, and the encapsulated edge means you can use the full width of the bed.

Key benefits
- More room each: You get 75cm each for two people sharing, which means 7.5cm more per person than the UK double offers, enough to stop elbows meeting at night.
- Extra length for taller partners: At 200cm long, the UK king is 10cm longer than the UK double, so a partner over six foot is less likely to have their feet hanging off the end.
- Quieter nights on split schedules: The 2,000 pocketed springs each move on their own, so when one of you gets up hours before the other, the movement stays mostly on that side.
- Usable edges across the full width: Full foam encapsulation around the springs keeps the edges supportive, which matters on a UK king because you can spread out right to the side without feeling you might roll off.
- Space for pillows and repositioning: The extra width gives a pregnant partner room to prop up pillows and shift position without pushing the other person towards the edge.
This size suits you if...
You share the bed every night and keep bumping into each other on a UK double, or one of you is tall enough that length matters as much as width. It also suits you if you and your partner keep different hours and want the early riser's movements to disturb the other a little less.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m, or you sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Sleepeezee Memory Ultimate 4500 UK king big enough for two tall people?
For length, yes for most couples. At 200cm, the UK king is 10cm longer than the UK double and matches the UK super king for length, so sizing up further won't add any. If you both sleep spread out, the UK super king gives 90cm each against the UK king's 75cm.
Will I feel my partner moving on a Sleepeezee Memory Ultimate 4500 king size?
Less than on a narrower bed. The pocketed springs move independently, and the UK king's 75cm per person puts a little more distance between you than the UK double's 67.5cm. Across couples with different working hours, that combination is usually what reduces the early-morning jolt, although you may still notice a partner getting in heavily.
Sleepeezee Memory Ultimate 4500 king or super king for a couple?
The UK king suits most couples, giving 75cm each while needing a room of at least 2.7m x 2.9m. The UK super king gives 90cm each, 15cm more per person, but we suggest at least 3m x 2.9m. If you share with a dog or sleep starfish, the extra width may be worth the space.
Will a UK king Sleepeezee Memory Ultimate 4500 fit in a new build master bedroom?
Measure after the wardrobes and furniture are in, as new build rooms often feel smaller once filled. We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m comfortable. If your room falls short, the UK double needs at least 2.6m x 2.8m.
Is the Sleepeezee Memory Ultimate 4500 king size good during pregnancy?
The UK king's width helps, as there's room for a pregnancy pillow and frequent position changes without crowding your partner. The graphite memory foam contours around the hips, and the encapsulated edges make getting in and out steadier. Lightweight side sleepers may find the medium-firm feel slightly firm at the shoulder, though.
