Layer Details
Cover
A knitted, microquilted soft-touch cover, which means a slightly cushioned, cosy surface the moment you lie down. It's designed for enhanced airflow and breathability, so warmth doesn't build up against your skin.
Comfort Layer
Eco Comfort Fibre fillings that are 100% sustainable and made from recycled materials. They offer cooling and breathability, so you get cushioning without the heat retention some foams can bring.
Support System
1000 individual Mirapocket springs, each encased in its own fabric pocket and strengthened by polyester walls. Because each spring responds independently to your body shape, you get pressure relief where you sink and support where you don't.

Key benefits
- A shared size that fits real rooms: At 135 x 190cm, the UK double fits comfortably in most UK bedrooms, usually with space left for bedside tables on both sides.
- 67.5cm each for two sharing: Two people get 67.5cm each, which the independent Mirapocket springs make more workable, since each spring responds to one body without disturbing the other.
- Budget-friendly for a whole-house furnish: If you're kitting out several rooms at once, an entry-level double from a recognised brand keeps the main bedroom sorted without draining the budget.
- Breathable for two warm bodies: Two sleepers generate more heat than one, so the Eco Comfort Fibre fillings and airflow-focused cover matter more in a double than they would in a UK single.
- A sensible guest room choice: For a spare room that hosts visiting couples a few weekends a year, a medium-feel double at this price is easy to justify.
This size suits you if...
You share the bed every night and want the classic couples' size in a room where a UK king would feel cramped, you're furnishing a first flat or a whole house and need a dependable double without a big outlay, or you're setting up a guest room that occasionally sleeps two.
Consider another size if...
You and your partner both like space, or one of you is a restless sleeper, and your room measures at least 2.7m x 2.9m. In that case we'd recommend the UK king instead, which is 15cm wider and 10cm longer.

FAQ's
Is the Mirapocket 1000 UK double big enough for a couple?
Yes, for most couples. You get 67.5cm each for two people sharing, and because each of the 1000 Mirapocket springs moves independently, one person turning over is less likely to wake the other. Broad-shouldered pairs, or anyone who sleeps starfish-style, may find the UK king a better long-term fit.
What room size do I need for the Mirapocket 1000 double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That gives you walking space on both sides and room to open wardrobe doors. In a typical UK double bedroom this size sits well, whereas a UK king can dominate a smaller room.
Should a couple choose the UK double or the UK king in this mattress?
It comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, so it suits rooms below the 2.7m x 2.9m we suggest for a king. If you have the space and either of you is tall or spreads out, the UK king is the more comfortable choice.
Is the double Mirapocket 1000 a good guest room mattress?
It's well suited to that. A medium feel is the safest bet for guests you can't ask about firmness preferences, and the double size accommodates visiting couples as well as solo stays. The breathable fibre fillings also cope well in spare rooms that run warm in summer.
Will the Mirapocket 1000 double get up a narrow staircase?
At 135 x 190cm with a 24cm depth, it's a manageable size for most stairs, though pocket spring mattresses don't arrive rolled the way foam ones often do, so allow for the full footprint on turning stairs in older terraces or a tight new build landing. Measure your narrowest point before ordering.
