Layer Details
- Memory Foam. A memory foam layer that moulds to your body, which means pressure is eased from muscles and joints as you settle in. Expect a gentle cradle rather than a deep sink, given the firm overall feel.
- Mirapocket Springs. 1400 Mirapocket springs sit beneath the foam, each responding independently to your movement. In practice that means targeted support along your spine and less motion transfer across the bed.
Layer details from silentnight.co.uk product page, September 2026.
- The classic couples' footprint: At 135 x 190cm it fits comfortably in most UK bedrooms, where a UK king would start to crowd the floor space.
- 67.5cm each for two sharing: Each of you gets 67.5cm of width, and the 1400 Mirapocket springs respond independently, so a restless partner is felt less across that shared surface.
- Bedside tables on both sides: In a room of around 3m x 3m, a UK double usually leaves space for a table each, which matters more than a few extra centimetres of bed.
- Firm support without the sunk-in feel: The memory foam layer eases pressure at the surface while the firm sprung base keeps two sleepers from rolling towards the middle.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet are stocked everywhere, at every price point, unlike some larger sizes.
This size suits you if...
You share the bed every night and your bedroom sits in the typical UK range, or you sleep alone and want room to stretch out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, where a firm, supportive mattress pleases most sleepers without dominating the space.
Consider another size if...
You're both broad-shouldered, tall, or simply find 67.5cm each a squeeze. The UK king is 15cm wider and 10cm longer, and we'd recommend it instead if your room allows at least 2.7m x 2.9m.

Will the Silentnight Memory 1400 in a UK double fit a small bedroom?
Usually, yes. We suggest allowing at least 2.6m x 2.8m of floor space, which covers most UK second bedrooms and first flats. That leaves room to walk round the bed and open drawers, though squeezing in a wardrobe and chest of drawers as well takes some planning in the tightest rooms.
Is the UK double Silentnight Memory 1400 big enough for a couple?
For most couples, yes. You get 67.5cm each for two people sharing, and the 1400 Mirapocket springs move independently, which softens the effect of a partner turning over in a bed this width. If one of you sprawls or you're both broad, the UK king's extra width is worth considering.
Should I choose the Silentnight Memory 1400 in a UK double or a UK king?
It comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, so if you can allow at least 2.7m x 2.9m and still fit your furniture, the UK king gives a couple noticeably more space. If not, the UK double is the safer buy.
Will a UK double mattress get up a narrow staircase?
Measure before you order. At 135 x 190cm this is a substantial mattress, and turning stairs in older terraces or tight new build landings can be awkward. Check the tightest corner on the route to your bedroom, and confirm handling details with the retailer you buy from before delivery day.
