Layer Details
- Cover. An in-house woven cover that meets fire safety standards without FR chemicals, which means fewer additives next to your skin. A small but genuine plus for anyone conscious of what goes into their bedding.
- Wool comfort layer. A layer of British wool sits near the surface, giving that plush, sumptuous first impression when you lie down. Wool also handles temperature well, so it stays comfortable through the night.
- Blend comfort layer. A blend of cotton, hemp and flax wicks moisture away from you as you sleep. In practice that means a fresher, drier feel, particularly useful if you run warm.
- Hemp and Ecotex layer. Layers of hardwearing hemp and strong Ecotex fibres add structure to the mattress. This helps reduce dips forming in the surface over time.
- Micro springs. A layer of 2500 micro springs provides additional bounce that adapts to your body. These respond quickly as you move, so changing position feels easy rather than effortful.
- Pocket springs support system. The base is 1000 Cortec Quad Revolution pocket springs, each with a smaller support spring nested inside a larger comfort spring, wrapped in a cloth pocket and secured in groups of four. The result is a softer initial feel backed by deeper support when you need it.

- Room to sleep apart, together: The UK king is 15cm wider than the UK double, which means you can both change position without ending up shoulder to shoulder.
- Less disturbance from a restless partner: The 1000 pocket springs move independently, and across a 150cm width one of you getting up early is far less likely to wake the other.
- Extra length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, a genuine relief if either of you is approaching six foot.
- A softer feel that still shares well: The Cortec Quad Revolution springs firm up as you press deeper, so two sleepers of different weights each get support across their own side.
- Natural fillings across a bigger surface: British wool, cotton, hemp and flax wick moisture over the full 150cm width, useful when two bodies are adding warmth to one bed.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially if one of you gets up hours before the other and you'd rather not feel every movement. It also makes sense if either partner is tall, since the extra 10cm of length over a UK double matters more than you'd think, or if a dog has quietly claimed a corner of the bed.
Consider another size if...
Your bedroom can't comfortably take it: we suggest at least 2.7m x 2.9m for a UK king. If space is tight, we'd recommend the UK double instead, which needs around 2.6m x 2.8m and still shares reasonably well.

Is the Bronze 3500 in a UK king big enough for two adults?
Yes, comfortably for most couples. A UK king gives 75cm each for two people sharing, 15cm more overall width than a UK double. Because the Bronze 3500 has a soft to medium feel, heavier couples who want firm pushback may prefer a different mattress, but for space alone the UK king suits most pairs.
Will a UK king Bronze 3500 fit in my bedroom?
The mattress measures 150 x 200cm, which is 5ft x 6ft 6in. We suggest a room of at least 2.7m x 2.9m so you can walk around the bed and open drawers, with more space feeling noticeably better. Measure with wardrobes and bedside tables in place, as a new build master can be smaller than it first looks.
Does the UK king reduce partner disturbance on this mattress?
It helps on two fronts. The extra width over a UK double means less accidental contact when one of you shifts, and the pocket springs compress individually rather than as one unit. So if one partner leaves for work hours before the other, the movement transfers far less than it would on a smaller open coil bed.
Is the UK king long enough if my partner is over six foot?
It's the length that makes the difference here. The UK king is 10cm longer than the UK double at 200cm, which usually stops feet hanging over the edge for anyone around the six foot mark. If length is your only issue, this size solves it; the UK super king adds width, not length, as both are 200cm long.
