Key benefits
- Sized for an ordinary bedroom: We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m comfortable, which means most UK main bedrooms keep space for a wardrobe and a walkway.
- Space for two bedside tables: At 15cm narrower than the UK king, a UK double often leaves room for a bedside table on each side, so neither of you clambers over the other at night.
- Cooler when sharing closely: The CoolEase woven cover draws heat away from your body, which helps on a UK double where two sleepers lie fairly close together at 67.5cm each.
- Bedding is simple to buy: Standard double sheets are sold almost everywhere and a 200 x 200cm double duvet covers it, so you won't be hunting for unusual sizes.
- A proper bed for guests: In a spare room where visiting couples stay, a UK double gives them a genuine shared bed without swallowing the floor space you need the rest of the year.
This size suits you if...
You share the bed every night in a standard-sized bedroom and still want space for bedside tables, or you're kitting out a spare room for couples who come to stay. It also fits if you both sleep warm and want a cooling cover without giving up floor space to a bigger bed.
Consider another size if...
One of you is tall, or you both like generous personal space, as 67.5cm each can feel snug. We'd recommend the UK king instead, which needs a room of at least 2.7m x 2.9m.

FAQ's
Is the Silentnight Reflex 1600 UK double big enough for two people?
For most couples, yes. A UK double gives each of you 67.5cm of width, which is comfortable if you sleep fairly still. If one of you sprawls, the UK king gives 75cm each, so the UK double offers 7.5cm less per person.
What size bedroom do I need for a UK double Silentnight SleepResponse Reflex 1600?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. At the smaller end you may need to choose between bedside tables on both sides and a full-size wardrobe, so measure walkways as well as the bed footprint.
Silentnight Reflex 1600 UK double or UK king for a couple?
The UK king is 15cm wider and 10cm longer than the UK double, and we suggest at least 2.7m x 2.9m for it. Choose the UK king if one of you is tall or restless; stay with the UK double if your room is tighter.
What bedding fits a UK double Silentnight Reflex 1600 mattress?
Double sheets fit the 135 x 190cm surface and a 200 x 200cm double duvet covers it. The mattress is 26cm deep, so check the pocket depth on any fitted sheet before buying, as shallow ones can pull off the corners.
Is a UK double or UK small double better for couples sharing?
The UK double is 15cm wider than the UK small double and the same length. That extra width makes a real difference for two adults every night. The UK small double, which needs at least 2.4m x 2.8m, suits a solo sleeper better.
