Layer Details
- Knitted cover. A soft knitted finish that adds a cosy, warm feel to the sleep surface. It's designed to help airflow and breathability rather than trap heat.
- Wool and Silk comfort layer. Natural wool and silk fibres with moisture wicking properties, which means they draw dampness away from your body to help regulate temperature. A nice touch at this price point.
- Polycotton comfort layer. A cotton and polyester blend that keeps the comfort layers breathable. It sits between the natural fibres and the fillings below.
- High density white fibres. Dense fibre fillings that give the mattress its body and cushioning. These sit directly above the springs to soften the surface feel.
- Pocket springs. 1400 pocket springs, each encased in its own fabric pocket so it moves independently. In practice, that means the mattress adapts to your shape and limits how much you feel a partner's movement.

- The most width you can get: At 30cm wider than the UK king, the UK super king is the largest mainstream UK size, which means two adults can sleep with clear space between them.
- Distance on top of independent springs: The 1400 pocket springs move individually, and 90cm each adds real physical distance, so a partner who tosses and turns is far easier to sleep through.
- Room when the family piles in: If a child or a large dog regularly ends up in bed with you, the extra body takes space from the middle rather than squeezing you towards the edge.
- Firm support across a wide surface: The firm pocket spring build keeps a large bed supportive where several people share it, although lightweight side sleepers may still find it a little unforgiving.
- In proportion with a large bedroom: In a period property or a generous master bedroom, a UK king can look slightly lost against the walls, and the UK super king fills the space properly.
This size suits you if...
You share the bed every night with a partner who moves a lot and want 90cm each, or children and dogs often join you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your room is tighter than 3m x 2.9m, or your stairs and landing turns are narrow. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

Is the Sleepeezee Luxury 1400 super king big enough for two adults and a child?
It gives 90cm each for two people sharing, the same width as a UK single for each adult. A small child can settle between you without either of you being pushed to the edge. The pocket springs limit how much movement travels across the bed, though a wriggling child will still be felt a little.
How much more room per person does a super king give than a king?
The UK super king gives 15cm more each than the UK king, which offers 75cm each for two sharing. Both are the same length, so the whole gain is in width. If a restless partner is the reason you're shopping, that extra 15cm each is where you'll notice the difference.
Is a firm super king mattress good if my partner is a restless sleeper?
For most couples, yes. The 1400 pocket springs respond independently, and at 90cm each there is enough distance that movement on the far side rarely reaches you. Lightweight side sleepers may find the firm feel a little unforgiving, and across owner reviews some describe it as closer to medium-firm.
Will a UK super king mattress fit in a loft conversion bedroom?
It can, but the sloping ceiling usually decides which wall the bed goes against, because you need headroom where you sit up. We suggest at least 3m x 2.9m of floor space. Measure the loft stairs and any tight turns before ordering, as 180cm of width is hard to angle round a narrow landing.
Can a large dog share a super king bed comfortably?
A UK super king is the most practical size for it. At 180 x 200cm, a dog can settle at the foot or between you and you still keep your own space. Bear in mind that super king sheets and a 260 x 220cm duvet are a larger bedding outlay than king sets.
