Layer Details
- MemorySense foam. Sealy's MemorySense foam sits on top and contours to your shape, easing weight off pressure points like hips and shoulders. You feel it as a gentle, relieving cradle rather than a firm surface.
- Reflex Foam. A firm Reflex foam layer follows, contouring to your body while stopping you sinking too deeply. In practice this keeps the memory foam feel shallow and supportive, which makes changing position easier.
- PostureTech Core Support Springs. Sealy's PostureTech springs form the core and become firmer when met with pressure, so support increases exactly where your body pushes hardest. The tops of the springs are made to a softer tension, which means they follow your shape rather than feeling rigid.

- 75cm each for two people sharing: Each of you gets your own stretch of MemorySense foam to settle into, so you contour into your own spot rather than rolling towards each other.
- Less disturbance on different schedules: If one of you leaves for work hours before the other, the slow-moving memory foam surface plus the extra width keeps the early exit from waking the late sleeper.
- 200cm of length for taller sleepers: At 6ft 6in long, the UK king suits anyone approaching six foot who currently sleeps with their feet at the edge of a standard-length bed.
- Medium firm support across the full width: PostureTech springs firm up under pressure wherever you lie, so the middle and edges of this wide surface support you rather than sagging where you drift.
- A substantial build at a substantial size: The 31cm hotel-style depth reads as a proper centrepiece in a master bedroom, though you'll need deep-fitted king sheets to match.
This size suits you if...
You share the bed every night and a UK double no longer feels like enough, especially if one of you gets up much earlier and the other feels every movement. It also fits if either partner is tall, since the 200cm length gives feet room that standard 190cm sizes don't. If a dog has become a permanent fixture on the duvet, the extra width absorbs that too.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king. In that case we'd recommend the UK double instead, which needs at least 2.6m x 2.8m and is only 15cm narrower.

Is the Sealy Imperial Contract in a UK king big enough for a couple?
Comfortably, for most. The UK king gives 75cm each for two people sharing, and the medium firm memory foam surface means each of you settles into your own contour rather than sliding towards the centre. If you both like to starfish, or a dog claims a third share nightly, the UK super king adds another 30cm of width.
Will the UK king suit a tall sleeper?
Yes, and length is often the real reason to choose it. The UK king is 200cm long, which is 10cm more than the UK double, so anyone approaching six foot stops sleeping with their feet at the mattress edge. The UK super king is the same length, so sizing up beyond king buys width, never extra legroom.
Does the Sealy Imperial Contract UK king reduce partner disturbance?
Across a 150cm width, movement transfers less than on a smaller bed simply because you're further apart. The memory foam top layer also absorbs motion rather than bouncing it along the surface, which helps when one of you gets up hours before the other. It's a good pairing of size and construction for couples on different schedules.
What room size do I need for this mattress in a UK king?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they first appear, so measure with the furniture in place. If the numbers don't work, the UK double needs at least 2.6m x 2.8m.
