Layer Details
- Latex. A plush, adaptive material that responds to your body shape, which means pressure relief at your shoulders and hips without losing the firm feel underneath. It sits at the top, so it's the surface you'll actually feel.
- EcoMemory Fibre. Made sustainably from recycled plastic, this layer adds cushioning while letting air move through it. That breathability helps you stay cooler than a solid foam layer typically would.
- Eco Comfort Fibre. Silentnight's eco-friendly fibres, also made from recycled materials. They add a further layer of soft padding between you and the springs.
- Mirapocket Springs. 2000 pocket springs that respond individually to your shape, with zoning to support spinal alignment and posture. In practice that means less roll-together with a partner and targeted pressure relief where you need it.

- Proper space for two: The UK king is 15cm wider than the UK double, enough that you can both change position without negotiating.
- Less partner disturbance: The 2000 zoned Mirapocket springs respond individually, which means an early alarm on one side transfers less movement across the extra width.
- Length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, a real difference if one of you is approaching six foot.
- Firm support across the full width: The zoning keeps your hips supported wherever you settle, so neither sleeper drifts into a dip in the middle.
- Latex comfort without the sink: The latex top layer contours at your shoulders and hips, so the firm feel stays comfortable even with more surface to spread across.
This size suits you if...
You share the bed every night and a double has started to feel like a compromise, especially if one of you keeps different hours and gets up hours before the other. It also suits taller couples, since the 200cm length gives someone approaching six foot room to stretch out. If your bedroom offers at least 2.7m x 2.9m, the UK king fits without dominating the space.
Consider another size if...
Your room is under our suggested 2.7m x 2.9m minimum, or you sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m and still gives a solo sleeper generous space on this firm hybrid.

Is a UK king big enough for a couple on a firm mattress?
Yes, and arguably more important on a firm mattress than a soft one. The Silentnight Lift Replenish sits you on the surface rather than in it, so you notice your share of the bed. In the UK king that's 75cm each for two people sharing, comfortably more than a double offers.
Will I feel my partner getting up on the Silentnight Lift Replenish king?
Less than on many mattresses. The 2000 Mirapocket springs move individually rather than as a connected unit, and the UK king's 150cm width puts more distance between you. If one of you leaves for work hours before the other, that combination makes early exits easier to sleep through.
Is the UK king long enough if I'm over six foot?
At 200cm (6ft 6in), the UK king gives a taller sleeper meaningful headroom, and it's 10cm longer than the UK double. If you've been sleeping diagonally or with feet at the edge, the length is often the upgrade you'll notice first, more than the width.
What room size do I need for this mattress in a UK king?
We suggest at least 2.7m x 2.9m, with more feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they look on paper, so measure the floor with furniture in place before committing to the 150 x 200cm footprint.
Should I choose the UK king or UK super king for this mattress?
The UK king is 30cm narrower than the UK super king, and both are the same length. If you share with a restless partner, or a dog that claims its own patch each night, the UK super king adds real breathing room, but it needs a room of at least 3m x 2.9m.
