Layer Details
Pillow top
An extra comfort layer containing mini pocket springs. It gives the surface a softer, more cushioned feel than the medium rating alone suggests.
Comfort fillings
Silk, cashmere, cotton and soft white fibres sit over the spring core. They add softness at the surface and a plush feel as you settle in.
Pocket spring core
2850 pocket springs, with firmer springs on the outer rows (Calibar Edge). The core provides the main support, and the firmer edges help the sides hold up.

Key benefits
- More room each: Each of you gets 75cm of width, which means 7.5cm more space per person than a couple has on the UK double.
- Length for taller partners: At 200cm, or 6ft 6in, it's 10cm longer than a UK double, so a partner over six foot has a better chance of keeping their feet on the mattress.
- Steadier sides: Firmer springs on the outer rows give the edges more support, which helps on a king where each of you tends to sleep nearer your own side.
- Same feel on both sides: The mini pocket spring pillow top sits across the whole sleeping surface, so whichever side you take, you get the same medium, cushioned feel.
- Easier to rotate: Yes, the pillow top means it can't be flipped, but turning handles make rotating a mattress of this width more manageable for two people.
This size suits you if...
You share a bed and keep disturbing each other on a UK double, or one of you is over six foot and keeps running out of length. Your bedroom should also clear our suggested minimum of 2.7m x 2.9m.
Consider another size if...
Your bedroom falls short of our suggested 2.7m x 2.9m, or you mostly sleep alone. The UK double would suit you better, and we suggest at least 2.6m x 2.8m for it.

FAQ's
What are the dimensions of the Relyon Luxury Silk 2850 in a UK king?
The UK king measures 150 x 200cm, or 5ft x 6ft 6in. Compared with a UK double, it's 15cm wider and 10cm longer, so you gain room in both directions.
Is a UK king big enough for two people to sleep without disturbing each other?
It gives 75cm each, which is 7.5cm more per person than a UK double. That extra space helps when one of you gets up hours before the other. Relyon doesn't publish motion isolation figures, so if partner movement wakes you easily, the UK super king gives 90cm each.
What room size do I need for a UK king mattress?
We suggest at least 2.7m x 2.9m, and 3.2m x 3.2m is comfortable. Main bedrooms in new builds can feel smaller once fitted wardrobes go in, so measure from the wardrobe doors rather than the walls.
Should a tall couple choose a UK king or UK super king?
Both are 200cm long, so a partner over six foot gets the same length on either. The UK super king adds width, giving 90cm each against 75cm on the UK king. We suggest at least 3m x 2.9m for the UK super king.
What bedding fits the Relyon Luxury Silk 2850 UK king?
Standard UK king sheets fit, and a 230 x 220cm king duvet covers it. At 32cm deep, this is a tall mattress, so check that your fitted sheet's pocket is deep enough before you buy.
