Key benefits
- Room to spread out on your own: The UK small double is 30cm wider than the UK single at the same length, so a solo sleeper can turn over and stretch out without reaching the edge.
- Fits a compact double bedroom: We suggest at least 2.4m x 2.8m for the UK small double, which means a modest main bedroom or a loft conversion can take it and still leave a walkway.
- Comfortable for an occasional couple: Two people can share the UK small double for a weekend visit, although couples who sleep together every night will be more comfortable on the UK double.
- A cooler surface in a smaller room: The CoolEase woven cover draws heat away from your body, which helps in a small bedroom or a top-floor room where the air can feel a little close.
- Straightforward to dress: Four foot is a standard UK width, so you can buy small double fitted sheets for the 26cm depth and cover the bed with a standard double duvet.
This size suits you if...
You sleep alone and want more width than a single gives you, your bedroom or loft conversion would feel cramped with a 4ft 6in frame in it, or the bed mainly sits in a guest room where couples stay a night or two at a time.
Consider another size if...
You and a partner share the bed every night. We'd recommend the UK double instead, which gives 67.5cm each for two sharing, and we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
Can two adults share the Silentnight Reflex 1600 small double every night?
For the odd weekend, yes, two adults can share the UK small double. For nightly sharing, we'd recommend the UK double, which gives 67.5cm each for two sharing and is the same length. Allow at least 2.6m x 2.8m for the UK double.
What size bedroom do I need for a UK small double mattress?
We suggest at least 2.4m x 2.8m for the UK small double. That leaves space to get in and out of the bed and to open a door or wardrobe. If your room only just reaches that, measure the doorway and stairs too before you order.
Is the Silentnight Reflex 1600 small double long enough if I'm tall?
The UK small double is 190cm long, the same length as the UK single and UK double. If your feet already reach the end of a standard bed, the UK king is 10cm longer, although it needs a room of at least 2.7m x 2.9m.
Is a small double big enough for a teenager who has outgrown a single?
Usually, yes. The UK small double is 30cm wider than the UK single and the same length, so a growing teenager gets noticeably more room. We suggest at least 2.4m x 2.8m for the UK small double, which many children's bedrooms can manage where a UK double would crowd the floor.
What sheets and duvet fit a Silentnight Reflex 1600 small double?
Buy small double (4ft) fitted sheets, and check the pocket depth suits a 26cm mattress so the corners stay put. A standard double duvet covers the UK small double well, with a little overhang on each side.
