Layer Details
Knitted cover
A soft knitted top layer that adds cosiness while allowing airflow through the surface. That breathability helps you sleep a little cooler.
Eco Poly Comfort fibres
Plush recycled polyester fibres that give the surface its soft, cushioned feel. They also help extend the lifespan of the mattress.
Mem-Tech foam
Memory foam that adapts around your body, which means pressure is lifted from areas like hips and shoulders as you settle in. You'll feel a gentle, enveloping sort of comfort.
Eco Support Foam
A layer of recycled foam that adds a secure, durable feel beneath the softer comfort layers. It reinforces the support of the mattress while keeping a cushioned quality.
Eco titan insulator layers
These sit between the foams and the springs, dispersing pressure from the spring unit. The result is more even weight distribution across the mattress.
1000 Pocket+ springs
One thousand springs, each encased in its own cloth pocket, respond individually to your movements for personalised full body support. They're built with extra resilience to bounce back to shape even after being rolled.

Key benefits
- 75cm each for two people sharing: You each get 75cm of width, which means turning over or stretching out without negotiating for space.
- Less disturbance from a restless partner: Each spring sits in its own cloth pocket and responds independently, so an early alarm on one side is less likely to wake the other.
- Extra length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK Double, a real difference for anyone approaching six foot.
- Memory foam comfort across a wider surface: The Mem-Tech layer adapts around hips and shoulders wherever you settle, useful when two people spread out across a king.
- A sensible room footprint: We suggest a room of at least 2.7m x 2.9m, which most UK master bedrooms can manage more easily than a super king would.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially if one of you is up hours before the other and you'd rather not feel every movement. It also suits taller sleepers who want the extra length, or anyone whose dog has quietly made the bed part of its routine and takes more than its share.
Consider another size if...
Your bedroom is below our suggested 2.7m x 2.9m minimum, perhaps a new build master that feels smaller once the wardrobes go in. We'd recommend the UK double instead: the UK king is 15cm wider and 10cm longer, and we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
Is the Aspire Invigorate 1000 in a UK king good for couples?
Yes, and arguably it's the size where this mattress makes most sense for two. You get 75cm each for two people sharing, and the 1000 individual pocket springs mean one person's movement stays largely on their side. If you keep different hours, that isolation is the benefit you'll notice most.
Will a UK king Aspire Invigorate 1000 fit in my bedroom?
The mattress measures 150 x 200cm, or 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 comfortably. If your room falls short of that, the UK double is a slightly better fit, and we suggest at least 2.6m x 2.8m for it.
Is the UK king Aspire Invigorate 1000 long enough for tall sleepers?
At 200cm long, the UK king is 10cm longer than the UK Double, so anyone approaching six foot gains genuine foot room rather than sleeping diagonally. For tall people, that extra length is often the real reason to size up, more than the width.
How much more space does this give a couple than a double?
The UK king is 15cm wider than the UK Double and 10cm longer too. Spread between two people, that extra width is the difference between sleeping shoulder to shoulder and each having room to shift position, prop pillows or settle a restless night's sleep without disturbing the other.
