Comfort fillings
Cashmere and wool fillings give a luxuriously soft, gentle natural feel with breathability and moisture-wicking, which means you're less likely to overheat. They regulate temperature naturally across the seasons.
Support system
2,000 pocket springs, each encased in its own cloth pocket, adapt to your movement individually. That translates to personalised support and better weight distribution than springs that move as a single unit.

Key benefits
- Room to sleep apart, together: At 75cm each for two people sharing, you can both change position without negotiating for territory.
- Less disturbance at the seams: The 2,000 individually pocketed springs respond to each sleeper separately, so an early alarm on one side is less likely to wake the other.
- Length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, which stops feet hanging off the end for anyone nearing six foot.
- Natural fillings across a wider surface: Cashmere and wool wick moisture and regulate temperature, useful when two bodies are warming one mattress every night.
- A manageable room fit: We suggest a room of at least 2.7m x 2.9m, comfortably smaller than the space a UK super king demands.
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 suits you if one partner is approaching six foot and needs the 200cm length, or if a dog has quietly become a permanent third occupant.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m, or you sleep alone and the width would go unused. We'd recommend the UK double instead, which needs a slightly smaller room at 2.6m x 2.8m.

FAQ's
Is a UK king big enough for a couple on the Aspire Natural Cashmere 2000?
For most couples, yes. Two people sharing get 75cm of width each, noticeably more than a double offers, and the 2,000 pocket springs in this build react to each sleeper individually, so one person shifting or getting up early is less likely to travel across the mattress and wake the other.
Will the UK king Aspire Natural Cashmere 2000 suit a tall sleeper?
The UK king is 200cm long, which is 10cm longer than the UK double. That extra length is often the real reason taller sleepers upgrade, more than the width. If either of you is around six foot or over, this size removes the feet-over-the-edge problem without needing a bigger room than a UK super king would.
What room size do I need for this mattress in a UK king?
We suggest at least 2.7m x 2.9m so you can walk round the bed and open drawers without shuffling sideways. New build master bedrooms can be tighter than they first appear once fitted wardrobes go in, so measure the usable floor space rather than the room's headline dimensions before committing.
Should I go up to the UK super king instead?
The UK super king is 30cm wider than the UK king, though both are the same 200cm length, so you're paying for width alone. If your room meets our suggested 3m x 2.9m minimum for the UK super king and you both spread out, it's a fair upgrade. Otherwise the UK king is the more practical fit.
Where can I buy the Aspire Natural Cashmere 2000 in a UK king?
Stockists change, so the most reliable answer is the live comparison table on this page, which updates as retailers change their prices. Check the price shown against other sizes too, since the gap between a UK double and a UK king is sometimes smaller than you'd expect.
