Key benefits
- Fits the average UK bedroom: We suggest at least 2.6m x 2.8m of floor space, which most British bedrooms can offer while still leaving room for a wardrobe and drawers.
- Independent support for two: Each of the 1,400 pocket springs moves on its own, so your side of the bed responds to your weight, and your partner's side to theirs.
- Firm feel across the full width: The firmer, orthopaedic-style build means the edges and middle hold their shape, useful when two people are sharing 135cm.
- Bedding is easy and cheap to find: Double sheets and a 200 x 200cm double duvet are stocked everywhere, handy if you're furnishing a whole home and the budget is stretched thin.
- Room for bedside tables both sides: In a typical room, the UK double leaves enough wall either side for a table and lamp each, where a UK king often wouldn't.
This size suits you if...
You share the bed every night and want the classic couples' size that fits a normal British bedroom, you're kitting out a first flat or a full house and need a firm pocket spring bed without going oversized, or you're a solo sleeper who likes space to spread out, perhaps with a dog or cat claiming one corner.
Consider another size if...
You and your partner both like room to sprawl, or one of you is broad shouldered and 67.5cm each feels tight. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, though allow at least 2.7m x 2.9m of floor space for it.

FAQ's
Is a UK double Silentnight Pocket 1400 big enough for a couple?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, and because the 1,400 pocket springs move independently, a partner shifting position disturbs you less than on an open coil bed. Restless sleepers or taller, broader couples may prefer the UK king, which is 15cm wider and 10cm longer.
What room size do I need for the Silentnight Pocket 1400 in a double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows the 135 x 190cm mattress plus walking space, and in most rooms leaves enough wall on either side for bedside tables. If your room is smaller, the UK small double is 15cm narrower and we suggest at least 2.4m x 2.8m for it.
Should I get the Silentnight Pocket 1400 in a double or a king?
Choose the UK double if your bedroom is a typical UK size or you want the widest choice of affordable bedding. Choose the UK king if you both want more space: it's 15cm wider and 10cm longer than the UK double, but we suggest at least 2.7m x 2.9m of room for it, which not every bedroom can spare.
Will a double Silentnight Pocket 1400 fit up a narrow staircase?
At 4ft 6in x 6ft 3in it's a manageable size for most homes, but pocket spring mattresses shouldn't be bent sharply, so measure any turning stairs in older terraces or tight new build landings before ordering. If access is genuinely awkward, the UK single is 45cm narrower and the same length, though clearly only suits one sleeper.
Is the double a good size for a guest room?
It's the standard choice, since it comfortably hosts visiting couples as well as solo guests, and the firmer feel of this mattress suits a wide range of sleepers passing through. Check the room meets our suggested 2.6m x 2.8m minimum; if it doesn't, the UK small double is 15cm narrower and we suggest at least 2.4m x 2.8m for it.
