Layer Details
- UltraGel™ comfort layer. A gel infused layer that sits at the top and responds to your movements, which means cushioning that adapts as you shift position. Silentnight describes it as offering supreme comfort with strong pressure relief, so it should ease strain around hips and shoulders.
- Miracoil® springs. This spring system runs from head to toe rather than side to side, which is designed to keep your spine aligned through the night. It also helps prevent partner disturbance, so movement on one side of the bed transfers less to the other.
Layer details from silentnight.co.uk product page, September 2026.
- Fits a typical main bedroom: At 135 x 190cm (4ft 6in x 6ft 3in), the UK double leaves space for a wardrobe and drawers in rooms where a UK king would crowd the floor.
- Less disturbance at close quarters: With 67.5cm each, you sleep nearer your partner, so springs designed to reduce movement transfer matter more here than on the wider sizes.
- Space for bedside tables: We suggest at least 2.6m x 2.8m for the UK double, which in many rooms still leaves enough space for a bedside table on each side.
- A proper bed for guests: In a spare room, the UK double gives visiting couples a genuine shared bed, and the medium/firm feel suits back and combination sleepers.
- Simple to dress: Double sheets and a 200 x 200cm double duvet are sold almost everywhere, so you won't be hunting for specialist bedding to fit this mattress.
This size suits you if...
You share a bed with your partner in a typical UK bedroom and want to keep space for furniture, or you're setting up a spare room for visiting couples. It also helps if you both sleep mostly on your back or shift between positions, since the medium/firm feel is built for that.
Consider another size if...
You and your partner both want plenty of personal space, or one of you sprawls. We'd recommend the UK king instead, which gives 75cm each; we suggest at least 2.7m x 2.9m for the UK king.

How much space does each person get on the Silentnight UltraGel Miracoil Pillowtop UK double?
Two people sharing get 67.5cm each. That is fine for most couples who sleep fairly still, and the Miracoil springs are designed to limit how much of your partner's movement you feel. If you want more elbow room, the UK king gives 75cm each, so the UK double gives 7.5cm less per person.
Will a Silentnight UltraGel Miracoil Pillowtop double fit in my bedroom?
We suggest a room of at least 2.6m x 2.8m for the UK double, with around 3m x 3m feeling comfortable once a wardrobe and drawers are in. Measure your walk-around space before ordering, especially if you want bedside tables on both sides.
Silentnight UltraGel Miracoil UK double or UK small double for a small room?
The UK small double is 15cm narrower than the UK double and the same length, and we suggest at least 2.4m x 2.8m for it. It suits a solo sleeper in a second bedroom. For two people sharing every night, the extra width of the UK double is the better call.
Is the UK double UltraGel Miracoil Pillowtop long enough if you're tall?
The UK double is 190cm long, the same length as the UK single and UK small double. If either of you is tall and your feet already reach the end of your current bed, the UK king is 10cm longer, and we suggest at least 2.7m x 2.9m for the UK king.
Does the Silentnight UltraGel Miracoil Pillowtop double suit a solo sleeper with a pet?
Yes, 135cm of width leaves a sleeper room to spread out while a dog or cat takes a corner. Just bear in mind the medium/firm feel: lightweight side sleepers may find it a little too solid at the shoulder, whatever size they choose.
