Layer Details
- Top upholstery layer. Bonded British fleece wool and cotton sit directly beneath you, which means a breathable, naturally temperature-regulating sleep surface. Wool wicks moisture away, so you should feel less clammy than on foam.
- Middle upholstery layer. A layer of British fleece wool adds cushioning depth. It softens the surface slightly without undermining the firm, stable support beneath.
- Bamboo layer. Bamboo brings extra breathability and resilience to the comfort layers. It is a naturally airy fibre, helpful if you tend to overheat at night.
- Bottom upholstery layer. Layered British fleece wool and cotton cushion the transition between you and the springs. This stops you feeling the spring unit directly while keeping the response even.
- Spring system. 1,326 hand-nested vanadium steel pocket springs, arranged in a single layer within calico pockets. Because each spring moves independently, you get support that follows your shape and less disturbance from a partner turning over.

Layer details from vispring.com product page, September 2026.
- Room for two, space left for furniture: At 135 x 190cm, a UK double leaves floor space that a UK king would take up, which helps when a wardrobe and chest of drawers share the room.
- Bedside tables on both sides: We suggest at least 2.6m x 2.8m, while around 3m x 3m gives you a bedside table each and room to walk round the bed comfortably.
- Less disturbance at close quarters: With 67.5cm each you sleep nearer your partner than on a UK king, so springs that move independently help stop one person's tossing reaching the other.
- A modest profile on a bedstead: The UK double measures 4ft 6in x 6ft 3in, and its 21cm depth, plus around 6cm of doming, keeps it sitting low and tidy on a traditional frame.
- Simple to dress: Double sheets and a 200 x 200cm double duvet are sold almost everywhere, so finding bedding for this mattress takes no searching at all.
This size suits you if...
You share the bed with a partner and your bedroom sits around our suggested 2.6m x 2.8m minimum, or you sleep alone and like room to stretch out, even with a cat curled up at the foot of the bed.
Consider another size if...
You and your partner want more elbow room than 67.5cm each and your bedroom can take a bigger bed. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

Is the Vispring Bedstead Realm UK double wide enough for two people?
It gives 67.5cm each, which suits most couples who don't mind sleeping fairly close. Because each pocket spring moves on its own, a partner rolling over should disturb you less than on an older open-coil mattress. If you both sprawl, the UK double gives 7.5cm less each than the UK king.
Will a UK double Vispring fit in my bedroom with bedside tables?
We suggest at least 2.6m x 2.8m for a UK double. At that size the bed fits, but space around it will feel a little tight. Around 3m x 3m is the comfortable norm, leaving room for a bedside table either side and a clear path to the wardrobe.
What size bedstead do I need for a Vispring UK double?
Look for a frame made for a 4ft 6in x 6ft 3in mattress, which is 135 x 190cm. The 21cm depth plus around 6cm of doming is shallower than many modern mattresses, so it sits comfortably inside most bedstead frames without towering over the side rails.
Is the Vispring UK double long enough if I'm tall?
The UK double is 190cm long, the same length as the UK single. If your feet already reach the end of your current bed, the UK king is 10cm longer as well as 15cm wider, though it needs a larger room of at least 2.7m x 2.9m.
Is a Vispring Bedstead Realm UK double a good choice for a guest room?
For a spare room that hosts visiting couples, yes. It sleeps two, fits most second bedrooms and takes standard double bedding. Bear in mind the supportive feel: guests who prefer a soft, sink-in bed may find it firmer than they're used to.
