Layer Details
Soft Touch Quilted Cover
A quilted fabric finish that gives a smooth, breathable sleep surface. It adds a slightly softer first impression to what is otherwise a firm mattress.
Memory Foam
Memory foam, a material originally designed by NASA, moulds to the shape of your body, which means orthopaedic-style support where you need it. It's the layer that softens the firm feel just enough at your pressure points.
Supportive Miratex® Foam
Silentnight's Miratex foam conforms to your body as you sleep and provides edge to edge support across the entire mattress. In practice, that means a consistent feel whether you sleep in the middle or near the side.

Key benefits
- Room to sleep apart, together: With 75cm each for two people sharing, you can shift position or stretch out without ending up in your partner's space.
- Extra length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, which matters if either of you is approaching six foot.
- Edge to edge support across the full width: The Miratex foam base supports right to the sides, so the sleeper nudged towards the edge still gets a consistent feel.
- Firm support at a bigger size: The memory foam layer moulds to hips and shoulders while the firm base keeps your spine aligned, useful when two people share every night.
- A slim profile that's easier to handle: The 15cm depth makes this UK king less awkward to manoeuvre up stairs and around landings than a deeper mattress in the same size.
This size suits you if...
You share the bed every night and the double has started to feel cramped, or your partner gets up hours before you and you want enough width that their movement doesn't wake you. It also fits if one of you is tall, since the 200cm length gives welcome extra room, and your bedroom offers at least 2.7m x 2.9m.
Consider another size if...
Your bedroom is under our suggested minimum of 2.7m x 2.9m, or you mostly sleep alone. We'd recommend the UK double instead, which needs a smaller room, at least 2.6m x 2.8m by our guidance.

FAQ's
Is the Silentnight Hush Comfort UK king big enough for two adults?
Yes, comfortably for most couples. The UK king measures 150 x 200cm, which gives 75cm each for two people sharing. That's 15cm more width than the UK double, enough that you each have a clear side of the bed rather than negotiating the middle, and the Miratex base supports edge to edge so neither side feels less stable.
Will a Silentnight Hush Comfort king fit in my bedroom?
We suggest a room of at least 2.7m x 2.9m for a UK king, and that's our guidance rather than Silentnight's. A new build master can be tighter than it looks once fitted wardrobes go in, so measure the free floor after furniture, allowing space to walk around the bed and open drawers.
Is the UK king Hush Comfort long enough for someone over six foot?
At 200cm, or 6ft 6in, it's 10cm longer than the UK double, which is often the difference between feet hanging over the end and a proper night's sleep. If length rather than width is your reason for upgrading, the UK king delivers it without the extra room demands of a UK super king.
Is the Hush Comfort in a king hard to get upstairs?
Less so than most mattresses this size. The 15cm depth keeps it slimmer and easier to handle than deeper king mattresses, which helps on narrow staircases and tight landings. It's still 150cm wide, so a second pair of hands is sensible, but the shallow profile makes the turns far more manageable.
Where can I buy the Silentnight Hush Comfort in a UK king?
Compare the retailers listed on this page, where prices are updated as retailers change them. Availability in the UK king can differ from the UK single and UK double, so if you're set on this size it's worth checking the live table rather than assuming every stockist carries it.
