Layer Details
- Dunlopillo® Plus Sleep Surface. A cooling fabric that stays around 1°C below your body temperature, which means the surface should feel fresher when you get in. A small detail, but a welcome one if you tend to overheat.
- Natural Talalay Latex. 100% natural Talalay latex that contours to your body, so you get pressure relief without losing the firm support underneath. It is also hypoallergenic and highly breathable, a sensible pairing for allergy sufferers and warm sleepers alike.
- VENTRA™ Core Performance System. An aerated foam core engineered to boost airflow through the mattress. In practice, this means heat has somewhere to go rather than building up beneath you overnight.

- Less partner disturbance: Talalay latex recovers quickly when one of you moves, which means an early alarm on one side is less likely to travel across 150cm of mattress.
- Real space for two: At 75cm each for two people sharing, a firm surface has room to do its job without you both drifting into the middle.
- Extra length for taller sleepers: The UK king is 10cm longer than the UK double, which matters more than width if one of you is approaching six foot.
- Firm support across the full width: The natural Talalay latex keeps its firm, responsive feel edge to edge, so the extra space is genuinely usable rather than a soft border.
- Different schedules, easier exits: A firm, fast-responding surface makes getting out quietly simpler, useful when one of you leaves for work hours before the other stirs.
This size suits you if...
You share the bed every night and a double leaves you brushing elbows, or one of you gets up much earlier and you want movement to stay on its own side. The 10cm of extra length over a UK double also makes this the sensible pick if either of you is tall, and your bedroom clears our suggested minimum of 2.7m x 2.9m.
Consider another size if...
Your room falls short of 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. If a dog routinely claims a share, the UK super king is the better buy, allowing at least 3m x 2.9m.

Is the Dunlopillo Firmrest UK king big enough for a couple?
Yes, comfortably for most. You get 75cm each for two people sharing, and because the Firmrest is firm rather than sink-in soft, that width stays usable right to the edges. The quick-responding Talalay latex also helps keep one partner's movement from disturbing the other, a real advantage over sharing a smaller size.
How much bigger is the UK king Firmrest than the double?
The UK king is 15cm wider and 10cm longer than the UK double, at 150 x 200cm overall. The width is what most couples notice night to night, but the length is the deciding factor for taller sleepers, since 200cm gives someone approaching six foot proper clearance on this firm latex surface.
What room size do I need for the Firmrest in a UK king?
We suggest at least 2.7m x 2.9m. That allows walking space on both sides and room for bedside tables, which matters more with a firm mattress you'll want easy access to on both edges. If your room is smaller, the UK double version needs at least 2.6m x 2.8m and may fit better.
Should I get the Firmrest in a king or a super king?
The UK super king is 30cm wider than the UK king, and the two are the same length. If a dog or child regularly joins you, or you both spread out, the extra width is genuinely useful, but you'll need a room of at least 3m x 2.9m. For most couples the UK king is the more practical fit.
Is the king size Firmrest good for reducing partner disturbance?
It's a strong choice for this. Talalay latex springs back quickly rather than transmitting a slow ripple, and the 150cm width puts real distance between you. Across a firm surface like this, one person turning over or getting up early tends to register far less on the other side than it would on a double.
