Layer Details
Wool comfort layers
Two layers of natural wool, described as 100% British wool. They give a soft, cosy top that feels cushioned when you lie down.
Cashmere and silk layer
A blend of cashmere and silk that gives a plush, indulgent feel, which adds to the softness of the surface.
Seasonal comfort layer
A blend of wool, tencel, bamboo and alpaca fibres described as refreshing, which adds natural fibre comfort to the upper layers.
Mini pocket springs
An extra 1550 mini pocket springs sit above the main springs. They add a cosy, sprung cushioning on top of the support layer.
Pocket springs
1500 pocket springs, each in its own fabric pocket, form the core. Each spring works individually, so the support follows your body's shape.
Dense polyester layer
A dense orthobond polyester layer that improves durability, helping the mattress hold up over time.

Key benefits
- More room each than a UK double: At 75cm per sleeper, each of you gets 7.5cm more than on a UK double, which means a little more distance when one partner turns over at 3am.
- Length for taller sleepers: The 200cm length is 10cm longer than a UK double, so a partner over six foot is far less likely to have their feet hanging off the end.
- Softer feel spread across a bigger surface: The pillow top and natural fibre layers give the whole UK king a cushioned top, which suits couples who both prefer to sink in slightly.
- Steadier sides for using the full width: Relyon's reinforced Calibar Edge should make the outer strip feel more stable, so the 150cm width stays usable right to the edge rather than tapering off.
- Pocket springs that work individually: Each of the 1500 springs moves on its own, so the support follows each body separately instead of the two of you sharing one dip.
This size suits you if...
You share the bed every night and the UK double has started to feel cramped, one of you is over six foot and tired of feet off the end, or your schedules differ and you'd like a bit more space between you when an early riser gets up.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once wardrobes and bedside tables are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Will a UK king Relyon Lydia 3050 fit in my bedroom?
We suggest allowing at least 2.7m x 2.9m for a UK king, and around 3.2m x 3.2m if you want comfortable room to walk round both sides. New build master bedrooms can feel smaller once fitted wardrobes go in, so measure the floor space you'll actually have left, not the room on the plan.
Is the Relyon Lydia 3050 UK king long enough for someone over six foot?
The UK king is 200cm long (6ft 6in), which is 10cm longer than the UK double. For a tall partner, that extra length often matters more than the width, because it stops heels and toes pressing against the footboard or hanging over the end.
How much more space do you get in a UK king than a UK double?
The UK king is 15cm wider and 10cm longer than the UK double. Shared between two, the UK double gives 67.5cm each while the UK king gives 75cm each, so you each gain 7.5cm. That sounds modest on paper, but it's enough to stop elbows meeting most nights.
Is a UK king big enough for two during pregnancy?
A UK king gives each of you 75cm, which leaves more room for a pregnancy pillow and frequent position changes than a UK double would. The medium soft pillow top suits side sleeping, and the steadier Calibar Edge should help when getting up during the night.
What size duvet and sheets fit a UK king Relyon Lydia 3050?
Use king size bedding with a 230 x 220cm king duvet. The mattress is 38cm deep, so choose fitted sheets labelled as extra deep and check the pocket depth on the packaging, as standard king fitted sheets may not reach under the corners.
