Layer Details
Bonded British fleece wool and cotton
A bonded layer of British fleece wool and cotton sits at the top. Bonding keeps the fillings in place, which means the surface stays smoother for longer.
British fleece wool
A layer of pure British fleece wool. Wool breathes and wicks moisture, so the sleeping surface feels drier through the night.
Bamboo
A bamboo layer chosen for its temperature-regulating and hypoallergenic properties. A sensible inclusion if you sleep hot or have sensitive skin.
Layered British fleece wool and cotton
Further layered wool and cotton cushioning between you and the springs. This softens the transition onto the firm spring unit slightly, without undermining the overall firm feel.
Hand-nested calico pocket springs
1,326 vanadium steel pocket springs, each in its own calico pocket and hand-nested in a single layer. Hand-nesting means the springs are stitched to one another, giving stable, independent support across the whole surface.

Key benefits
- Room for two without filling the room: At 135 x 190cm, the UK double leaves floor space for furniture, and we suggest a bedroom of at least 2.6m x 2.8m.
- Independent springs suit sharing: The 1,326 hand-nested pocket springs move independently, which means a restless partner on their 67.5cm side is less likely to jolt you on yours.
- An easy guest room choice: Visiting couples get a proper shared bed, and standard double sheets and a 200 x 200cm double duvet fit it without any hunting around.
- Sits neatly in a bedstead: The slim 21cm profile, plus around 6cm of doming, suits a double bedstead and keeps the bed from looking bulky in a smaller room.
This size suits you if...
You share the bed most nights and want space for a bedside table on each side, or you're furnishing a second bedroom or guest room where visiting couples should sleep well without the bed crowding the wardrobe.
Consider another size if...
You and your partner want more elbow room, or either of you finds 190cm too short. We'd recommend the UK king instead, which is 10cm longer; we suggest at least 2.7m x 2.9m for the UK king.

FAQ's
How much room does each person get on a UK double Vispring Bedstead Realm Firm?
Sharing the UK double gives you 67.5cm each. That is 7.5cm less each than the UK king, so it suits couples who sleep fairly close. The independently moving pocket springs help here, because a partner shifting position is less likely to travel across to your side.
Will a UK double Vispring mattress fit a small bedroom?
We suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m feeling comfortable. At the minimum you can usually fit a bedside table on each side, but measure for wardrobe doors and drawers opening before you order.
What is a UK double Vispring Bedstead Realm Firm in feet and inches?
The UK double measures 4ft 6in x 6ft 3in, or 135 x 190cm. This mattress is designed for bedstead bases, so check your frame is made for a standard UK double before buying. You can then compare the retailers listed on this page.
Is the UK double long enough if you're tall?
The UK double is 190cm long. If either of you finds your feet reaching the end, the UK king is 10cm longer as well as 15cm wider, and we suggest at least 2.7m x 2.9m for the UK king. The UK single is the same length as the UK double.
Is a UK double worth it for one person with a dog?
Often, yes. The UK double is 45cm wider than the UK single, which leaves room for a dog or cat to claim a corner while you keep your own space. Yes, it needs a bigger room, but we suggest at least 2.6m x 2.8m for the UK double against 2.1m x 2.8m for the UK single.
