Layer Details
Intense™ sleep surface
The sleep surface uses Intense™ fabric technology, which Silentnight says is scientifically proven to help your body relax for deeper, undisturbed sleep. It's Oeko-tex® approved and free from FR chemical treatments, a reassuring point if you're sensitive to what's in your bedding.
Luxurious Latex
A latex layer sits beneath the surface, providing cushioning comfort and pressure relief. Because latex moves when you do, your weight is evenly distributed and you keep a sense of freedom of movement rather than feeling stuck.
Spring system
The base combines 1,000 mini springs with 600 Mirapocket® springs that adjust to your movements. The result is zoned support, with tailored give at the hips and shoulders where side sleepers need it most.

Key benefits
- Proper space for two: At 150 x 200cm the UK king is 15cm wider than the UK double, which means you each get room to spread out rather than negotiating the middle.
- Less partner disturbance: The 1,000 mini springs and 600 Mirapocket® springs adjust to movement locally, so an early alarm on one side is easier to sleep through on the other.
- Length for taller sleepers: The UK king is 10cm longer than the UK double, a difference anyone approaching six foot feels every night, particularly on a softer surface where feet can otherwise hang.
- Softness that suits sharing: The latex layer moves with you as you change position, which means shifting closer or further from a partner doesn't leave you feeling stuck.
- Fits most main bedrooms: We suggest a room of at least 2.7m x 2.9m, which most UK master bedrooms manage without giving up wardrobe space.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially with a medium soft mattress that rewards having your own space to sink into. It also suits you if one of you is tall, since the 200cm length is a genuine relief around the six foot mark, or if you keep different hours and want movement on one side to fade before it reaches the other.
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 keeps the same medium soft latex feel.

FAQ's
Is the Silentnight Lift Rejuvenate Hybrid 1600 in a UK king good for couples?
Yes, and arguably better than firmer hybrids at this width. With 75cm each for two people sharing, you both have room to settle, and the latex layer eases pressure at hips and shoulders without you rolling towards each other. Heavier couples may find the medium soft feel too plush, though; that's a feel issue rather than a size one.
How much bigger is the UK king than the double for this mattress?
The UK king is 15cm wider and 10cm longer than the UK double. The width is the difference you feel nightly as a couple, while the extra length helps if either of you is tall. On a medium soft mattress like this one, that extra space also means less chance of drifting into your partner's dip.
Will I feel my partner moving on the UK king size?
Less than you might expect. The combination of 1,000 mini springs and 600 Mirapocket® springs responds where the pressure is rather than across the whole surface, and the 150cm width puts more distance between you than a double does. If one of you gets up hours before the other, both factors help.
What room do I need for this mattress in a UK king?
We suggest at least 2.7m x 2.9m, and that's our guidance rather than Silentnight's. New build master bedrooms can be tighter than they look once fitted wardrobes go in, so measure the usable floor, not the room. If you're comfortably over that minimum, a UK king should leave walking space on both sides.
Should I pick the UK king or the UK super king?
The UK super king is 30cm wider than the UK king, and both are the same 200cm length. If a dog routinely claims part of the bed, or you both want serious space, the UK super king is tempting, but we suggest at least 3m x 2.9m of room for it. For most couples the UK king is the practical middle ground.
