Layer Details
- Microquilted cover. A micro-quilted cover gives the surface a smooth, soft finish. It's the first thing you'll feel when you lie down.
- Soft White Fibres. Soft synthetic fillings sit just beneath the cover, which means a cosy, cushioned initial feel.
- Bamboo Memory Foam. A plush layer of bamboo memory foam moulds around your body. This is where the pressure relief comes from, particularly at the hips and shoulders.
- High density foam. A layer of high density foam adds durable comfort and motion isolation. In practice, that means less disturbance when a partner moves.
- Pocket Springs. 2000 pocket springs, each enclosed in its own fabric pocket, respond individually to your weight. An additional layer of 1000 mini springs brings the total to 3000.
- Reinforced foam border. A thick foam border runs around the edge to stop it sagging. Helpful if you tend to sleep near the side of the bed.

- 90cm each, every night: Two people sharing get 90cm each, which means a partner who tosses and turns is far enough away that the movement rarely reaches you.
- Motion isolation plus distance: The high density foam layer already dampens movement, and at this width the sheer space between you does most of the remaining work.
- Room for the whole household: Children arriving at 3am or a large dog treating the bed as routine still leave adults with a usable share of the mattress.
- Medium firm across a wide surface: The 2000 pocket springs plus 1000 mini springs respond to each sleeper individually, so two different body weights get support without a shared dip.
- Edges you can use: The reinforced foam border matters more at 180cm wide, where sleeping near the side is normal, though some owners have raised concerns, so test it during your trial.
This size suits you if...
You share every night and want the maximum space a standard UK size offers, your partner is genuinely restless and distance matters more to you than any comfort layer, or children and pets regularly join you and 90cm each keeps that workable. Your bedroom should be at least 3m x 2.9m, with a larger master feeling more comfortable around it.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest, or you struggle to justify super king bedding costs. The UK king is 30cm narrower and the same length; we'd recommend it instead, allowing at least 2.7m x 2.9m.

What room size do I need for a super king Horizon Eclipse 3000?
We suggest a bedroom of at least 3m x 2.9m for a UK super king, and that's our guidance rather than Horizon's. That allows walking space on both sides and room for bedside tables. In a large master or period property, a UK king can look undersized, which is often what prompts the move up.
Is the Horizon Eclipse 3000 super king good for restless couples?
Yes, arguably the best size of this mattress for it. The high density foam layer limits how far movement travels, and the 90cm each of a UK super king adds physical distance on top. Across a hybrid this wide, one person turning over at the far side is genuinely hard to notice.
Will a super king mattress get up my stairs?
At 180 x 200cm and 27cm deep, this is the trickiest standard size to move. Measure your stairwell, landing turns and door swing before ordering, because a hybrid with 3000 springs doesn't fold the way an all-foam mattress might. If access is tight, the UK king is 30cm narrower and noticeably easier to manoeuvre.
Is a super king big enough for co-sleeping with children?
It's the size most parents land on. With 6ft of width, a child wandering in during the night can settle between you and both adults keep a reasonable share. The pocket springs support each person independently, so a lighter child and two adults each get appropriate support rather than rolling together.
How much support do two sleepers get at this width?
Each of the 2000 pocket springs and 1000 mini springs compresses independently, so a heavier and a lighter sleeper each sink to their own level. Spread across 180cm, that means no shared trough in the middle. The medium firm feel suits most sharers, although lightweight side sleepers may find it slightly too solid.
