Layer Details
- Stitchbond Cover. A hard-wearing polyester fabric with a quilted finish, which keeps costs down without feeling flimsy. The stitching attaches the outer fabric to the surface fillings, which means a flat, even sleeping surface rather than one that shifts about.
- White Fibre Fillings. A lightweight, high-loft filling that's hypoallergenic and holds its shape well. You get a soft initial feel, and the fibres are designed to keep their comfort over time.
- Open Coil Springs. Rows of hourglass-shaped springs joined at the top and bottom by a spiral helical wire, an interconnected system that's durable and gives a traditional bouncy feel. Because the springs are linked, movement does transfer across the bed more than it would with pocket springs.
- Wire Edge Border. A thick wire runs around the perimeter of the spring unit, which means firmer edges and a longer-lasting mattress. It also helps you use the full width of the bed without the sides sagging.

- More distance from a restless partner: Open coils do transfer movement, but 75cm each for two people sharing means you're further from the disturbance than you would be on a UK double.
- Length for taller sleepers: At 200cm long, the UK king suits anyone approaching six foot who finds their feet reaching the end of a standard 190cm mattress.
- A big bed at a small price: King sizes usually carry a premium, so pairing this width with an entry-level open coil mattress keeps the upgrade affordable.
- Usable width right to the edge: The wire edge border firms up the perimeter, which means you can sleep near the sides without them sagging, useful when two of you are sharing 150cm.
- Light enough to manage: At 20cm deep with fibre fillings, this is a shallower, lighter king than most, so turning or rotating it isn't a two-person wrestling match.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, especially if one of you shifts about or gets up hours before the other, since the extra width softens the movement those linked coils pass along. It also fits if one of you is approaching six foot and wants the 200cm length, or the dog has quietly claimed a strip of the bed and you'd like your side back.
Consider another size if...
Your bedroom can't comfortably take a 150cm-wide bed, or you mostly sleep alone. We'd recommend the UK double instead: it's 15cm narrower, easier to fit around wardrobes, and this mattress costs less in that size.

Is the Highgrove Solar Comfort UK king good for couples?
Yes, with a caveat. The interconnected open coil springs pass movement across the bed more than pocket springs would, so a light sleeper will still notice a partner turning over. The UK king's 75cm each for two people sharing puts more distance between you, which reduces how much of that movement you actually feel.
How much bigger is the UK king than the double in this mattress?
The UK king is 15cm wider than the UK double and 10cm longer, at 150 x 200cm against 135 x 190cm. The width is what most couples notice night to night, while the extra length is the real gain if either of you is tall.
What room size do I need for the Highgrove Solar Comfort in a UK king?
We suggest allowing at least 2.7m x 2.9m, with around 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they look on a floor plan, so measure the usable floor space before committing to a 150cm-wide bed.
Does the Solar Comfort come in a size larger than UK king?
No. The UK king, at 150 x 200cm, is the largest size Highgrove makes this mattress in. If you want the 180cm width of a UK super king, you'd need to look at a different mattress, as there's no super king option in this range.
Is the UK king long enough for someone over six foot?
At 200cm (6ft 6in), it gives a sleeper over six foot roughly 15cm of clearance, which is comfortable for most. It's also 10cm longer than the 190cm UK double and UK single, so if length is the reason you're upgrading, the UK king delivers it in this range.
