Layer Details
- Cover. A breathable Belgian damask fabric cover. It lets air move through the surface, which helps keep the sleeping surface fresher.
- Comfort Fillings. Resilient polyester comfort fillings with layers of soft white fibres. These sit between you and the springs, which means a softer initial feel that helps alleviate pressure points.
- Eco Comfort Fibres™. Breathable, sustainable fibres that are 100% recyclable. They've been scientifically proven to keep you cooler while you sleep, a helpful layer if you run warm at night.
- Support System. 1400 pocket springs, each mounted in its own separate fabric pocket. They work completely independently, which means support that follows your shape and less disturbance when a partner moves.

- 90cm each when you share: With 90cm of width per person, you can turn over or stretch out without meeting your partner's elbow halfway across the mattress.
- Distance plus independent springs: The 1400 pocket springs move separately, which means a partner's fidgeting stays mostly on their side, and the extra width between you does the rest.
- Space for a small visitor: When a child climbs in after a bad dream, the UK super king leaves enough room that nobody spends the rest of the night clinging to the edge.
- A firm base for a large dog: The firm feel suits a big dog that sleeps on the bed as routine, although a heavy dog will still claim a fair slice of the width.
- Every extra centimetre goes into width: Sizing up from the UK king adds 15cm per sleeper at the same 200cm length, so the gain goes where couples usually feel cramped.
This size suits you if...
You share the bed every night with a partner who tosses, kicks or gets up at odd hours, your children or a large dog regularly end up in with you, and your bedroom comfortably clears our suggested 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m, or you usually sleep alone. We'd recommend the UK king instead, for which we suggest at least 2.7m x 2.9m.

How much more space does the Venice Ortho 1400 UK super king give than the UK king?
The UK super king is 30cm wider than the UK king, and the two are the same length. When two of you share, that works out at 15cm more each: 90cm per person on the UK super king against 75cm on the UK king. If width is your complaint and length is fine, this is the size that addresses it.
Is a UK super king Venice Ortho 1400 good if my partner is a restless sleeper?
It is one of the better set-ups for it. The pocket springs work independently, so movement on one side travels less to the other, and 90cm each puts real distance between you. Yes, the firm feel won't absorb movement like deep foam would, but at this width the space matters more than any comfort layer.
Can two adults and a child sleep on the Venice Ortho 1400 super king?
For the odd night when a child wanders in, the 180cm width gives everyone a usable share rather than a sliver at the edge. As a nightly arrangement it gets tighter, especially with a restless child. Lightweight children may find the firm surface a little solid, so it suits occasional visits better than a permanent family bed.
What should I check before ordering a UK super king mattress for a loft conversion?
Start with the sloping ceiling: it usually decides which wall the headboard can go against, and you need standing room along both sides. Then check that the room clears our suggested 3m x 2.9m, that doors can swing open past the bed, and that the mattress can make the turns on your landing and stairs.
Is the Venice Ortho 1400 in a UK super king a good choice if my dog sleeps on the bed?
If a large dog joins you most nights, the UK super king is the size that leaves both people a proper share, with 90cm each before the dog arrives. The firm surface suits a dog settling at the foot. Bear in mind that super king bedding costs more to replace, which matters if you wash covers often.
