Layer Details
- Knitted cover. A soft knitted finish that adds a touch of cosiness, which means the firm surface underneath doesn't feel harsh against you. It's designed for airflow and breathability, helpful if you tend to sleep warm.
- Memory foam layer. A 5cm layer of memory foam that adapts to your body and moulds around your shape. This is what softens the firm feel at pressure points like hips and shoulders.
- Soft white fibre layer. A small fibre layer that works with the tufted finish to smooth out the sleeping surface. You'll feel it as a slightly softer top rather than foam sitting straight on firm padding.
- Dense soft white fibre layer. Densely packed fibres that reinforce the firmness of the mattress. This is where the firm character really comes from, sitting between the comfort layers and the springs.
- Pocket springs. 1,500 individual springs encased in cloth pockets, so each one responds to your body independently and movement transfers less across the bed. Firmer springs on the outer rows, which Relyon calls Calibar Edge, limit dipping when you sit or sleep near the side.

- More room each: At 75cm per sleeper you get 7.5cm more each than on a UK double, which means fewer elbows and knees crossing the middle when one of you sprawls.
- Calmer mornings on split schedules: Independent springs across a 150cm width mean the partner who gets up hours earlier can climb out with less movement reaching the one still asleep.
- Length for a tall partner: At 200cm long, the UK king adds 10cm over a UK double, so a partner over six foot is less likely to wake with feet over the end.
- Edges you can sleep on: Firmer Calibar Edge springs on the outer rows limit dipping, which matters on a UK king because each of you will use the width right up to your own side.
- Firm support for two: Yes, lightweight side sleepers may find it a little unforgiving, but two back or front sleepers get the same steady support across the whole 150 x 200cm surface.
This size suits you if...
You share the bed every night and have outgrown a UK double, one of you is over six foot and keeps running out of length, and you both prefer a firm surface for sleeping on your back or front.
Consider another size if...
Your bedroom is smaller than our suggested minimum of 2.7m x 2.9m. We'd recommend the UK double instead, which we suggest for rooms of at least 2.6m x 2.8m.

Is the Relyon Rufford UK king big enough for two people?
For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more per person than the UK double's 67.5cm. If you both sleep spread out, the UK super king gives 90cm each, although it needs a noticeably bigger room.
Is the Relyon Rufford UK king good for couples on different sleep schedules?
It suits them well. The pocket springs respond individually, and the extra width over a UK double puts a little more distance between you, so the early riser's movement travels less. The firmer outer rows also mean sitting on the edge to switch off an alarm causes less dipping.
Is the Relyon Rufford UK king long enough for someone over six foot?
At 200cm, the UK king is 10cm longer than the UK double, the UK small double and the UK single. That extra length is often the real reason tall sleepers upgrade. The UK super king is the same 200cm length, so sizing up beyond the UK king adds width only.
What size bedroom do I need for a Relyon Rufford king size mattress?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m giving comfortable room to walk around both sides. New build master bedrooms can feel smaller once wardrobes are fitted, so measure with furniture in place before you order.
Should I get the Relyon Rufford in a UK king or UK super king?
The UK king is 30cm narrower than the UK super king and gives 15cm less each, but the two are the same length. Choose the UK super king only if width is the problem and your room allows it: we suggest at least 3m x 2.9m for that size.
