Layer Details
- Damask cover. A finely woven damask fabric that's soft to the touch and doesn't retain heat, which means the sleep surface stays cooler than many synthetic covers. It's built for long-lasting performance too.
- Soft White Fibres. Soft synthetic fillings that create a cosy initial feel when you lie down. They're durable and resilient, so they should hold their shape rather than flattening quickly.
- Silk and polyester layer. A blended silk and polyester layer that's highly breathable. This increases airflow through the mattress, reducing heat and moisture buildup, which matters if you're a warm sleeper.
- Dual density polyester fibre pad. Soft and plush on the side facing you for comfort. The denser reverse side supports the spring system beneath, helping the layers work together.
- Pocket Springs. 1500 pocket springs, each encased in its own cloth pocket. Because they move individually, they adapt to your body and reduce the ripple effect when a partner moves.

- 90cm of width each: Two people sharing get 90cm apiece, which means you can both stretch out without negotiating over the middle of the bed.
- Distance plus independent springs: The 1500 pocket springs respond individually, and at this width a restless partner's movement has 180cm to fade across before it reaches you.
- Space when children wander in: A child or a large dog arriving at 3am is far easier to absorb across 6ft of width than on a smaller size.
- Airflow across a bigger surface: The breathable silk and polyester layer keeps heat and moisture moving, and two well-spaced sleepers share less body warmth to begin with.
- Medium firm comfort at full scale: The soft fibre layers give the same gentle surface feel edge to edge, so neither of you is stuck on a lesser side.
This size suits you if...
You share the bed every night and want the most space any standard UK size offers, your children or a large dog treat the bed as partly theirs, or a restless partner keeps waking you and you've realised distance solves what no comfort layer can. Your room should measure at least 3m x 2.9m, and closer to 3.5m x 3.2m will feel comfortable rather than crowded.
Consider another size if...
Your bedroom is under the 3m x 2.9m we suggest, or you mostly sleep alone. The Relyon Anna 1500 isn't made in a UK king, so we'd recommend the UK double instead: allow at least 2.6m x 2.8m for it.

What size room do I need for the Relyon Anna 1500 super king?
We suggest a minimum of 3m x 2.9m, which leaves walking space around a 180 x 200cm mattress. Around 3.5m x 3.2m feels genuinely comfortable, with room for bedside tables on both sides and a wardrobe you can actually open. In anything smaller, the bed starts to dominate the room.
Is the Relyon Anna 1500 super king good for a restless partner?
It's a strong pairing. The 1500 pocket springs each sit in their own cloth pocket and move independently, so one person turning over sends less ripple across the surface. Add 90cm of width each and most movement simply happens too far away to wake you. Width does as much work here as the springs.
How much more space does the super king give than the Relyon Anna 1500 in a double?
The UK super king is 45cm wider and 10cm longer than the UK double. For two people sharing, that means 90cm each rather than 67.5cm, a difference of 22.5cm per person. The feel of the mattress is identical in both sizes; you're paying for space, and the extra length suits taller sleepers too.
Is a super king big enough when children or pets join you at night?
It's the best-suited standard UK size for it. At 180cm wide, a child climbing in between you still leaves each adult a workable share, where a smaller size pushes someone to the edge. The same goes for a large dog with a settled routine of sharing. It won't feel roomy every night, but everyone sleeps.
