Layer Details
Knitted Cover
A soft knitted cover that's breathable, which means heat escapes rather than building up under you. It helps keep your temperature steadier through the night.
Comfort Fillings (Wool and Silk)
A wool and silk blend cushions your body, with high-density support layers beneath that mould to your shape. In practice, you sink in a little at the shoulders and hips while staying supported.
Comfort Fillings (Polyester and Cotton)
A polyester and cotton blend wicks away excess moisture, which means a fresher, drier feel against the fabric. Useful if you tend to overheat.
Support System
1,400 pocket springs, each in its own fabric pocket, work independently of one another. That gives more precise pressure relief and less disturbance when a partner moves.

Key benefits
- Distance from a restless partner: With 90cm each, you get 15cm more per person than on the UK king, so a partner who kicks or rolls is physically further from you.
- Room when children wander in: A small child climbing in at night can take the middle without pushing either adult towards the edge, which a UK double struggles to allow.
- Springs that move on their own: The 1,400 pocket springs respond independently, which means a dog settling at the foot or a child fidgeting beside you is felt less across the wider surface.
- Proportioned for a large room: In a spacious master bedroom or a high-ceilinged period room, the full 6ft width looks in scale where a UK king can seem slightly undersized.
- Length as well as width: At 200cm long it matches the UK king and is 10cm longer than the UK double, so taller sleepers gain legroom along with the extra width.
This size suits you if...
You share with a partner whose restlessness wakes you, or your children and pets regularly end up in your bed, and your bedroom comfortably clears 3m x 2.9m with space left to walk around.
Consider another size if...
Your bedroom falls short of 3m x 2.9m, or awkward doors and landings would make a 180cm mattress a struggle. We'd recommend the UK king instead; we suggest at least 2.7m x 2.9m for it.

FAQ's
How much wider is the Sleepeezee Hotel Luxury 1400 UK super king than the UK king?
The UK super king is 30cm wider than the UK king, while the two share the same 200cm length. For a couple, that works out at 90cm each on the UK super king against 75cm each on the UK king, so 15cm more per person.
Sleepeezee Hotel Luxury 1400 super king dimensions in feet?
The UK super king measures 180 x 200cm, which is 6ft x 6ft 6in. You'll need super king sheets to fit it and a 260 x 220cm duvet if you want the bedding to hang properly over both sides.
Is a UK super king enough for two adults and a child sleeping together?
For occasional night-time visits, yes. The 90cm each for two adults leaves a usable gap in the middle, and the independent pocket springs mean a wriggling child is felt less by whoever is furthest away. For every night co-sleeping, expect things to feel a little snug by morning.
Does the Sleepeezee Hotel Luxury 1400 super king suit sharing with a large dog?
It gives you the best chance among this mattress's sizes, since the UK super king is 30cm wider than the UK king. The medium tension and separately pocketed springs mean a dog shifting position at the foot is less likely to jolt you awake.
Is the UK super king worth choosing over the UK double for a light sleeper?
If your room allows it, yes. The UK super king is 45cm wider than the UK double and gives 22.5cm more space each for two sharing. For a light sleeper next to a restless partner, that distance tends to make a clearer difference than any comfort layer.
