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.

- The classic couples' footprint: At 135 x 190cm, the UK double is Britain's standard shared size, which means it works in rooms where a UK king would leave little walking space.
- Independent support for two: Each of the 1000 pocket springs moves on its own, so when your partner turns over you feel less of it on your side.
- 67.5cm each when sharing: Two people sharing get 67.5cm each, enough for most couples who sleep reasonably close, though restless sleepers will notice the limit.
- Room left for the furniture: Allow at least 2.6m x 2.8m and you should still fit bedside tables on both sides, which is where a UK king often forces a compromise.
- A medium firm feel that suits sharing: The medium firm balance of memory foam over springs works for two people with slightly different preferences, though very firm-mattress fans should look elsewhere.
This size suits you if...
You share the bed every night and your bedroom is a typical UK size, where you want space for two without the bed dominating the room. It also suits you if you sleep alone but like to spread out, or share with a dog or cat that claims a corner. And if you're kitting out a guest room for visiting couples, the UK double is the safe, expected choice.
Consider another size if...
You and your partner both move around at night and 67.5cm each sounds tight. Provided your room allows at least 2.7m x 2.9m, we'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double.

Is the Aspire Invigorate 1000 in a UK double big enough for two adults?
For most couples, yes. The UK double gives two people sharing 67.5cm each, and the 1000 pocket springs respond to each sleeper individually, so one person shifting disturbs the other less. If either of you is broad-shouldered or a restless sleeper, that width can feel snug, and the UK king is the step up to consider.
What room size do I need for the Aspire Invigorate 1000 UK double?
We suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That allows you to walk around the bed and, in most layouts, keep bedside tables on both sides. In a smaller second bedroom it will still fit, but expect tighter access on one side.
How much bigger is a UK king than this UK double?
The UK king is 15cm wider and 10cm longer than the UK double. That extra width is shared between you, so it's a noticeable rather than dramatic upgrade. You'll need more floor space too: we suggest at least 2.7m x 2.9m for a UK king, against 2.6m x 2.8m for the UK double.
Will the UK double fit through narrow stairs and landings?
It should manage better than most. The mattress arrives rolled, and Aspire builds the pocket springs with extra resilience so they return to shape after being unrolled. Rolled delivery makes turning the stairs in an older terrace or a tight new build landing far easier than manoeuvring a rigid 135 x 190cm mattress would be.
Is the UK double a good choice for a guest room?
It's the safest option. Visiting couples expect a double, the 135 x 190cm footprint leaves room for a wardrobe and drawers in a typical spare room, and double bedding is cheap and easy to find. The medium firm feel is a sensible middle ground for guests whose preferences you can't predict.
