Pocket Springs
1,200 pocket springs form the core of the mattress, and the body-moulding nature of the spring system means the surface adapts to your shape as you move. Each spring works independently, so support goes where your body needs it.

Key benefits
- A shared size for shared sleep: With 67.5cm each for two people sharing, a couple gets a workable amount of space without the bed dominating a modest bedroom.
- Independent springs where it matters: In a shared UK double, 1,200 pocket springs mean the mattress responds under each of you separately, so one restless sleeper disturbs the other less.
- Room for bedside tables: We suggest a room of at least 2.6m x 2.8m for a UK double, which in most bedrooms still leaves space for a table on both sides.
- Easier to get upstairs: At 135cm wide, a UK double negotiates the turning stairs of older terraces and tight new build landings more forgivingly than a UK king would.
- Bedding you can buy anywhere: Double sheets and duvets are stocked at every price point, so dressing this size is cheap and simple compared with the larger UK sizes.
This size suits you if...
You share the bed most nights and your room is an average UK size, or you sleep alone and want space to stretch out on a traditional pocket sprung surface. It also suits a guest room that hosts visiting couples, where a UK double is the expected standard and the body-moulding springs will please a range of sleepers you can't predict.
Consider another size if...
You and a partner both like space and your room comfortably exceeds 2.7m x 2.9m. We'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double, a real difference over years of shared nights.

FAQ's
Is the Hypnos Cotton Origins 7 double big enough for two adults?
Yes, for most couples. A UK double gives 67.5cm each for two people sharing, which is the long standing British standard. The 1,200 pocket springs help here: because each spring moves on its own, you feel your side of the bed rather than every shift your partner makes. Taller or broader couples may prefer the UK king.
What room size do I need for the Hypnos Cotton Origins 7 in a UK 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, in most rooms, enough clearance for bedside tables as well. If your room is closer to 2.7m x 2.9m or larger, the UK king becomes a realistic option too.
Should I choose the Hypnos Cotton Origins 7 in a double or a king?
It usually comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, so it suits bedrooms where a king would crowd the walls. We suggest at least 2.7m x 2.9m for the UK king. Couples with the space often prefer it; solo sleepers rarely need it.
Will a double mattress fit up a narrow staircase?
Usually, yes. At 135 x 190cm the UK double is the size most staircases in older terraces and tighter new builds were effectively built around, and it turns landings more easily than the wider sizes. Pocket sprung mattresses don't roll or fold, though, so measure any awkward turns before delivery day rather than after.
What bedding fits the Hypnos Cotton Origins 7 double?
Standard UK double bedding: double fitted sheets for the 135 x 190cm footprint and a 200 x 200cm double duvet. This is the most widely stocked bedding size in Britain, available everywhere at every price, which keeps the running cost of the bed down compared with the UK king or UK super king.
