- The classic couples' footprint: At 135 x 190cm, the UK double is the long-standing standard for two sharing, giving 67.5cm each for two people sharing.
- Fits typical UK bedrooms: We suggest a room of at least 2.6m x 2.8m, which most doubles-by-default British bedrooms already meet with space for bedside tables on both sides.
- Pocket springs on a budget: The 600 Mirapocket springs move independently, which means one of you turning over is less likely to wake the other.
- Sensible for a guest room: A medium-feel double suits the widest range of visiting sleepers, so overnight guests, couples included, get a proper bed rather than a compromise.
- Easy to dress and to move: Double sheets and duvets are stocked everywhere at every price, and the modest build makes this size easier to carry up a turning staircase.
This size suits you if...
You share the bed every night and want the traditional couples' size without spending king money, or you're kitting out a whole home at once and need a dependable double for the main or spare room. It also suits solo sleepers who like space to spread out, even with a cat or dog claiming a corner.
Consider another size if...
You and your partner both like room to sprawl, or your bedroom comfortably exceeds 2.7m x 2.9m. We'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double.

Is the Silentnight Essentials Pocket 600 UK double big enough for two adults?
It works for most couples. The UK double measures 135 x 190cm, which gives 67.5cm each for two people sharing. The zoned pocket springs help here, since each spring compresses independently and one sleeper's movement transfers less to the other. If either of you is tall or a restless sleeper, the UK king offers more room.
What room size do I need for the Pocket 600 in a UK double?
We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space on both sides and, in most rooms, bedside tables too. This is our own guidance rather than Silentnight's, so measure your room, including alcoves and door swings, before ordering.
Should I get the Pocket 600 in a UK double or a UK king?
It comes down to your room and how you sleep. The UK double is 15cm narrower and 10cm shorter than the UK king, so it suits rooms where a bigger bed would dominate. If your room meets our suggested 2.7m x 2.9m for the UK king and you both like space, sizing up is worth considering.
Is the UK double Pocket 600 a good choice for a guest room?
Yes, it's a sensible fit. The medium feel suits most sleeping positions, so it accommodates whoever visits, including couples, without you needing to guess their preferences. The affordable build makes more sense for occasional use than a premium mattress would, and double bedding is cheap and easy to find.
Will the Pocket 600 double fit up a narrow staircase?
At 135 x 190cm and 24cm deep, it's a more manageable carry than deeper premium doubles, which helps in older terraces with turning stairs or tight new build landings. Silentnight doesn't publish a boxed size or weight for this mattress, so if access is genuinely tight, check with the retailer you buy from before delivery.
