Layer Details
Cover
A wool-blend cover woven in-house, fire retardant without chemical treatments. That means natural flame resistance rather than sprayed-on chemistry.
Fillings
Responsibly sourced, fully traceable British wool, hemp and flax grown on the Harrison Spinks farm, alongside soft, breathable cotton. Natural fibres like these help regulate temperature, which matters if you tend to sleep warm.
Micro springs
A layer of 2,500 high-density micro springs, which means the surface can contour to your shoulders and hips even though the overall feel is firm. It's cushioning without softness, in effect.
Pocket springs
The award-winning Advanced Cortec pocket spring system uses a spring-within-a-spring design for dynamic support. In practice, the mattress responds differently to lighter and heavier pressure, adapting as you move.

Key benefits
- 11,000 springs in this size: The UK king holds 11,000 springs, which means the surface responds to each sleeper individually rather than tilting the whole bed when one of you turns.
- Room to sleep apart, together: At 75cm each for two people sharing, you can settle on different schedules without negotiating territory in the small hours.
- Length for taller sleepers: The 200cm length means anyone approaching six foot lies flat without their feet finding the end of the bed.
- Firm support that spans the width: The Advanced Cortec spring-within-a-spring system adapts to lighter and heavier pressure, so partners of different weights each get proper firm support on their own side.
- Natural fillings across a bigger surface: British wool, hemp and flax help regulate temperature, useful on a 150cm-wide mattress where two bodies generate more warmth than one.
This size suits you if...
You share the bed every night and want genuinely separate space, especially if your schedules rarely match and one of you slips out early. It also suits couples where one partner is tall, since the 200cm length adds headroom a standard-length bed lacks, or where a dog has quietly claimed a corner and 135cm was never going to be enough.
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 small double instead, which is 30cm narrower, and we suggest at least 2.4m x 2.8m for it.

FAQ's
Is the Pure Splendour Firm in a UK king big enough for two people?
Comfortably, for most couples. The 150cm width gives you 75cm each for two people sharing, and because the mattress is firm you tend to stay on your own side rather than rolling towards the middle. If either of you sprawls, or a pet joins you most nights, that extra width is where you'll feel the benefit.
Will I feel my partner moving on the UK king size?
Less than you might expect. The king size holds 11,000 springs, and pocket springs compress individually rather than as one unit, so movement stays fairly localised. Combined with 75cm each for two people sharing, one person getting up early is far less likely to wake the other than on a narrower mattress.
Is the UK king long enough for someone over six foot?
At 200cm, or 5ft x 6ft 6in overall, it suits most tall sleepers. The UK king is 10cm longer than the UK double, and that extra length is often the difference between feet hanging over the edge and lying flat. Very tall sleepers should still measure themselves against the 200cm figure before buying.
Should I choose the UK king or the UK super king in this mattress?
It usually comes down to your room. The UK king is 30cm narrower than the UK super king, and the two are the same length, so sizing up buys width only. We suggest at least 3m x 2.9m for the UK super king, against 2.7m x 2.9m for the UK king, so measure before you commit.
There's no double in this mattress, so is the UK king the right step up?
For most couples, yes. Harrison Spinks doesn't make the Pure Splendour Firm in a standard UK double, and the UK king is 15cm wider and 10cm longer than the UK double, so it's a modest jump in footprint for a real gain in space. If your room is tight, the UK small double is the alternative.
