Layer Details
Probiotic top layer
The top layer has a probiotic fabric treatment (Bio-Protect), described as a 100% natural treatment to protect against allergens. If allergens are a worry for you, that gives the surface a bit of extra protection.
Comfort layer
A comfort layer of fillings sits under the soft knitted, micro-quilted cover and adds softness to the surface. It takes the edge off the springs below, though the feel stays medium firm overall.
Pocket spring core
The core has 1,000 individually pocketed Posturepocket springs, which provide the main structure and support. Because each spring moves on its own, the mattress follows your shape and passes less movement across to a partner. The 1,000 figure is given for King size, so it may differ in other sizes.
Edge springs
Two firmer rows of pocket springs run around the outer edges. They give support right to the sides, so sitting on the edge or sleeping near it should feel steadier.

Key benefits
- Room for two, sized for real bedrooms: At 135 x 190cm, the UK double fits comfortably where a UK king would dominate, leaving space to actually walk around the bed.
- 67.5cm each when sharing: Two people sharing get 67.5cm of width each, and the 1,000 pocket springs move independently, so one partner turning over disturbs the other less.
- Bedside tables on both sides: Allow at least 2.6m x 2.8m and most rooms will still take a table each side, which matters more in a shared bed than extra mattress width.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet are sold everywhere at every price, so replacing bedding never becomes a hunt.
- A guest room that welcomes couples: In a spare room, a UK double with a medium firm tension handles visiting couples and solo guests alike without committing the space a UK king demands.
This size suits you if...
You share the bed every night in a typical UK bedroom and want the traditional couples' size, you're furnishing a spare room that needs to sleep visiting couples as well as single guests, or you sleep alone and want space to spread out, perhaps with a dog or cat claiming a corner. It also suits anyone who wants bedside tables on both sides without squeezing the room.
Consider another size if...
You and your partner both toss and turn, or one of you sleeps diagonally, because 67.5cm each can feel snug. The UK king gives 75cm each for two sharing; allow at least 2.7m x 2.9m for it.

FAQ's
Is the Relyon Comfort Pure 1000 in a UK double big enough for a couple?
For most couples, yes. Two people sharing get 67.5cm of width each, and because the 1,000 pocket springs respond to each sleeper separately, you'll feel less movement when your partner shifts than an open coil bed would transmit. If either of you is broad-shouldered or a restless sleeper, the UK king gives 75cm each instead.
What room size do I need for the Relyon Comfort Pure 1000 in a UK double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves space to open drawers and, in most rooms, fit bedside tables on both sides. The mattress itself measures 135 x 190cm, or 4ft 6in x 6ft 3in.
Should I buy the Relyon Comfort Pure 1000 in a double or a king?
The UK double is 15cm narrower and 10cm shorter than the UK king, and it gives 7.5cm less width each for two sharing. If your room comfortably exceeds our suggested 2.7m x 2.9m for the UK king and you share every night, size up. If space is tighter, the UK double keeps the room usable.
Is the UK double Relyon Comfort Pure 1000 the same length as the single?
Yes. The UK double and the UK single are both 190cm long; the UK double is 45cm wider. So if you're upgrading from a single for extra sleeping space, you gain width rather than length, and anyone over about six foot should note the UK king adds 10cm of length.
Does a UK double Relyon Comfort Pure 1000 work in a guest room?
It's a good fit. A UK double sleeps visiting couples as well as solo guests, and the medium firm tension is a safe middle ground for people whose preferences you don't know. Lightweight side sleepers may find it slightly firm at the shoulder, but for occasional stays that's rarely a dealbreaker.
