Layer Details
- Wool. Wool comfort fillings that stay cosy through the night, which means natural insulation in winter and temperature regulation in summer. It's the layer closest to you, so you feel its softness first.
- Cotton. Natural cotton fibres that wick away moisture, which means a fresher, drier sleeping surface. Helpful if you run warm at night.
- Hemp. An eco-friendly fibre that's naturally breathable and durable, adapting to different temperature conditions. It also acts as a natural insulator, adding to the mattress's temperature control.
- Soft White Fibres. Soft synthetic fillings that add a cosy feel while staying resilient. This layer holds its shape over time, so the comfort shouldn't flatten quickly.
- Eco-polyester. A supportive layer made from 100% recycled materials, and it can be recycled again at the end of its life. A quiet win if sustainability matters to you.
- Pocket Springs. 3750 Cortec Quad Core pocket springs, each encased in its own cloth pocket, which means each spring responds independently to your body. The design prioritises breathability and resilience.

- 90cm each, every night: Two people sharing get 90cm apiece, which means a partner who turns over constantly is simply too far away to wake you.
- 3750 springs across a wider bed: The Cortec Quad Core pocket springs respond independently, so movement on one side of this 6ft width barely travels to the other.
- Space for the whole household: When children or a large dog treat your bed as theirs, a UK super king means everyone still gets a fair share.
- Natural fillings suit a big master: Wool, cotton and hemp regulate temperature without foam, useful when two adults plus occasional visitors are generating heat under one duvet.
- Turning handles matter at this size: The natural fillings need regular turning, and on a 180cm-wide mattress the built-in handles stop that being a two-person wrestling match.
This size suits you if...
You share the bed every night and one of you is a genuinely restless sleeper, because distance does more than any comfort layer can. It also suits you if young children or pets regularly join you, or if you have a large master bedroom where a UK king would look undersized against the wall.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest, or you'd struggle to turn a mattress this wide regularly. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs a room of at least 2.7m x 2.9m.

How much space do two people get on a super king Levisham 3750?
With 180cm of width, two people sharing get 90cm each. That's the same width per person as a UK single, so you can both stretch out, change position and sleep at different times without disturbing each other. The 3750 pocket springs help too, since each one moves independently rather than the whole bed shifting.
Is the Levisham 3750 in a UK super king hard to turn?
It's the biggest regular turning job in the range. At 180 x 200cm you'll want two people for the task, but the built-in turning handles give you something to grip, which makes a real difference at this width. Regular turning helps the wool and hemp fillings settle evenly and last longer, so it's effort well spent.
How much bigger is a UK super king than a UK king?
The UK super king is 30cm wider than the UK king, and the two are the same length. That extra 30cm is roughly the difference between sensing a partner's every movement and barely noticing it. If your room can take it, we suggest at least 3m x 2.9m for the UK super king, the width is what you'll feel every night.
Is a super king Levisham 3750 big enough when children climb in at night?
This is where the size makes sense. At 6ft x 6ft 6in there's genuine room for a small visitor between you without anyone hanging off the edge, and the independent pocket springs mean a child wriggling in the middle doesn't bounce the whole bed. Parents in that stage of life are exactly who this size is built for.
What room do I need for the super king Levisham 3750?
Allow at least 3m x 2.9m, which is our own guidance rather than the manufacturer's, and around 3.5m x 3.2m feels comfortable with bedside tables on both sides. In a loft conversion, check the sloped ceiling too: a bed this size limits which wall it can go against, so measure the usable head height first.
