Layer Details
Cover
A soft knitted fabric with a traditional tufted design. The tufting anchors the fillings in place, which means the surface stays even and the sturdy feel lasts.
Comfort Layer
Soft white synthetic fibres that create a cosy top feel. They are durable and resilient, so they hold their shape rather than flattening quickly.
Support System
1600 traditional pocket springs, each encased in its own cloth pocket. They adapt to your movement individually, which means support is distributed to each part of your body rather than the whole surface tilting when you shift.

Key benefits
- Room to lie apart: With 90cm each, you get 15cm more per person than the UK king, so you can sleep without an elbow or knee finding you in the night.
- A restless partner registers less: The 1600 springs sit in separate pockets and move individually, which means a partner turning over at the far edge should disturb you a little less across this width.
- Space for small visitors: When a child wanders in at 3am, a 6ft wide bed means there is somewhere to put them without one adult ending up clinging to the edge.
- Firm across the full width: The firm feel means less sinking where a child or dog lies between you, so you are less likely to find yourself rolling towards the middle.
- In proportion in a large room: In a generous master bedroom or a period property with high ceilings, 6ft x 6ft 6in fills the space where a UK king can look undersized.
- Plan the floor space first: We suggest a room of at least 3m x 2.9m, and nearer 3.5m x 3.2m if you want comfortable walking room around the bed.
This size suits you if...
You and your partner keep waking each other, a child or a large dog joins you most nights, or your bedroom is big enough that a UK king would look a little lost in it.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m, or your stairs and landing turns are tight. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Sleepeezee Luxury Ortho 1600 super king big enough for two adults and a child?
For occasional visits, yes. You each start with 90cm, and a small child in the middle takes a share from both of you, so it gets snug but stays workable. The firm feel helps, because the surface sinks less where the child lies. If a child joins you every night as they grow, expect the space to feel tighter over time.
Ortho 1600 super king vs king: is the extra width worth it?
The UK super king is 30cm wider than the UK king and the same length, giving each of you 15cm more. If your partner is restless, that extra distance often helps more than any change of mattress feel. The trade-off is floor space: we suggest at least 3m x 2.9m for the UK super king against 2.7m x 2.9m for the UK king.
Will I feel my partner moving on a super king Sleepeezee Ortho 1600?
You should feel less than on a narrower size. The pocket springs respond individually, and at 90cm each there is more mattress between you and your partner. Yes, a firm mattress can pass on some movement, but the added distance on a UK super king softens that. Very light sleepers may still notice a heavy partner getting into bed.
Will a super king mattress fit in a loft conversion bedroom?
Often, if the floor area meets our suggested 3m x 2.9m. The slope usually decides which wall the bed goes against, so check the head height along the side you'll get in from. Before ordering, measure the door swing and any tight turns on the loft stairs, because a UK super king at 25cm deep is a lot to manoeuvre.
Is the Sleepeezee Ortho 1600 in super king good if my dog sleeps on the bed?
If a large dog shares the bed as routine, the UK super king gives you the best chance of keeping your own 90cm. Dogs tend to claim the middle or the foot, and the extra width leaves room for everyone. The firm surface also means the mattress sinks less under a heavy dog curled up in one spot.
