Layer Details
Pressure-relieving memory foam
A memory foam layer designed to relieve pressure. It contours to your body, which should cushion your shoulders and hips.
Platinum 3D
A recyclable layer Dreams says has the feel of a million tiny springs. It gives the mattress a springy, responsive feel.
Open coil springs
Open coil springs that add bounce and airflow for lasting freshness. You get a lively feel and better air movement than all-foam builds.

Key benefits
- 90cm each for two sharers: Each sleeper gets 90cm of width, which means a partner who turns over at 3am is much further away and much easier to sleep through.
- Room for children and pets: When a child wanders in or the dog settles at your feet, the 6ft width means the adults still keep a usable share of the medium surface.
- Same length as the UK king: The UK super king is 30cm wider than the UK king but the same length, so all the extra space goes into width rather than legroom.
- 15cm more per person than a UK king: Couples moving up from a UK king gain 15cm each, which means more room to spread out if either of you sleeps with arms and legs flung wide.
- In proportion in a large room: In a period property's main bedroom or a generous loft conversion, a UK king can look small, while the UK super king fills the space more naturally.
This size suits you if...
You share with a partner who moves a lot in the night, your children or a large dog regularly end up in bed with you, and your bedroom gives you at least 3m x 2.9m, ideally nearer 3.5m x 3.2m.
Consider another size if...
Your bedroom falls short of 3m x 2.9m, or you mostly sleep alone. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
What size room do I need for a Dreams Workshop Richards Combination super king?
We suggest at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling more comfortable. In a loft conversion, the sloping ceiling usually decides which wall the bed goes against, so measure the full-height area rather than the floor.
How much bigger is a UK super king than a UK king?
The UK super king is 30cm wider than the UK king, and both are the same length. When two of you share, that means 90cm each instead of 75cm, so you gain 15cm per person.
Is a UK super king big enough for two adults and a child?
For occasional visits, yes. Two adults get 90cm each on the Richards Combination in a UK super king, so a small child arriving at night is less likely to leave anyone clinging to the edge. If it happens most nights, the extra width over a UK king matters even more.
What size duvet fits a UK super king mattress?
A 260 x 220cm duvet fits a UK super king, along with super king sheets. Bedding at this size can cost more than for smaller beds, so include it in your budget alongside the Richards Combination itself.
Will a 6ft super king mattress fit up my stairs?
At 180 x 200cm and 22cm deep, the Richards Combination is a large single piece to carry. Check how your bedroom door opens, the landing turns and the stair width before ordering, then compare the retailers listed on this page.
