Layer Details
- Knitted Cover. A soft knitted cover that breathes well, which means heat is less likely to build up around you overnight. It should help keep your temperature fairly even until morning.
- Reflex Foam. A generous layer of reflex foam that contours to your shape, cushioning your frame at every curve. You feel this as gentle give at pressure points rather than a deep sink.
- Open Coil Springs. An open coil system made from high-tensile steel joined in a lattice shape, giving medium tension support across your whole body. Open coils move together as one unit, so expect a slightly bouncier, more connected feel than pocket springs.

- Room for two: At 135 x 190cm, or 4ft 6in x 6ft 3in, the UK double gives each sleeper 67.5cm, which is enough for most couples who sleep fairly close together.
- Fits a typical bedroom: We suggest at least 2.6m x 2.8m for a UK double, so it usually leaves space for a wardrobe and drawers where a UK king would crowd the floor.
- Bedside tables on both sides: In a room nearer 3m x 3m, the UK double generally leaves a clear strip on each side for a bedside table and a comfortable way in and out.
- Sensible when budgets are spread thin: If you are kitting out a whole home at once, a low cost UK double lets you furnish the main bedroom properly without starving the rest of the list.
- Easy bedding: Double sheets are sold almost everywhere, and a 200 x 200cm double duvet fits the UK double without hunting for specialist sizes.
This size suits you if...
You want a shared bed for a spare room where visiting couples stay a night or two, or you are furnishing a first flat on a tight budget and need two people to fit comfortably in a modest bedroom.
Consider another size if...
You share every night, one of you is a restless sleeper, and you want more personal space. We'd recommend the UK king instead, and we suggest at least 2.7m x 2.9m for it.

Is the Spring King Premier UK double good for couples?
For many couples, yes, with one caveat. The UK double gives you 67.5cm each, which suits partners who sleep close. The open coil springs move as one connected unit, though, so a restless partner is more likely to disturb you than on pocket springs. For guest use that rarely matters; for nightly sharing with a fidget, it might.
How much extra space does the Spring King Premier UK king give over the UK double?
The UK king is 15cm wider and 10cm longer than the UK double. Shared between two, that works out at 7.5cm more each, 75cm rather than 67.5cm. The trade-off is room size: we suggest at least 2.7m x 2.9m for the UK king, against 2.6m x 2.8m for the UK double.
Will a UK double Spring King Premier fit in my bedroom with bedside tables?
Allow at least 2.6m x 2.8m for a UK double. That is our minimum, and in a room at that size bedside tables on both sides can feel tight. Around 3m x 3m is the more comfortable norm, leaving space to walk round the bed and open drawers without shuffling sideways.
Is the Spring King Premier UK double long enough for tall sleepers?
The UK double is 190cm long, or 6ft 3in, the same length as the UK single and UK small double. If either of you is tall and your feet already reach the end of the bed, the UK king adds 10cm of length as well as width.
Is the Spring King Premier in a UK double a good choice for a guest room?
It suits a guest room well if the people staying tend to be couples. The UK double gives two visitors a proper shared bed without taking over a second bedroom, and the medium feel should suit most guests for a few nights. If your guests usually come alone, the UK small double saves 15cm of width and needs at least 2.4m x 2.8m.
