Comfort fillings
A blend of silk and polyester fibres sits at the surface. It gives the top a soft, comforting feel over the firmer layers below.
Additional fillings
Soft white fibres and a polyester and cotton blend add breathability and cosy comfort. That helps the surface feel cushioned without losing air flow.
Polyester fibre pad
A densely packed polyester fibre pad finishes the build. It adds to the firm feel, so the mattress stays supportive.
Pocket spring core
A core of 1000 individual pocket springs, each in its own fabric pocket. The springs move independently, so the mattress supports you closely across its surface.

Key benefits
- Room for a restless partner: With 90cm each for two people sharing, a partner who tosses and turns stays further away, which means fewer of their movements reach your side.
- Space when children arrive: The UK super king is the largest size UK retailers stock as standard, so a child arriving at 3am can slot in without someone ending up on the edge.
- Steadier edges across a wide bed: The Calibar Edge uses firmer outer springs, which helps when a family spreads out and somebody ends up sleeping close to the side.
- Firm support across the whole width: The 1000 individual pocket springs move independently, which means each person, child or dog is supported where they lie rather than rolling towards the middle.
- Scaled for a large master bedroom: In a period property or a big master bedroom, a 6ft x 6ft 6in bed looks in proportion where a UK king can seem a little lost.
This size suits you if...
You share with a partner who moves a lot and want real distance between you, children or a large dog regularly join you overnight, or your bedroom comfortably clears 3m x 2.9m and you prefer a firm, supportive bed.
Consider another size if...
Your bedroom falls short of our suggested 3m x 2.9m, or a wide bed would block a door. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is a Relyon Cerrado Pillowtop UK super king big enough for two adults and a child?
It's the widest standard UK size, giving two adults 90cm each before anyone else climbs in. A small child can usually find room between you. The firmer outer springs of the Calibar Edge help too, because whoever gets pushed towards the side still has a steadier surface under them.
What size bedroom do I need for a Relyon Cerrado Pillowtop super king?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling right once you add bedside tables and space to walk round. In a loft conversion, measure where the ceiling slope sits first, because the slope often decides which wall the headboard can go against.
Will a UK super king Relyon Cerrado Pillowtop fit up my stairs?
At 180 x 200cm and 36cm deep, it's a large item to carry, so check the retailer's handling guidance before buying. Measure tight landing turns and see which way the bedroom door swings, then compare the retailers listed on this page.
UK king or UK super king Relyon Cerrado Pillowtop for a restless partner?
The UK super king is 30cm wider than the UK king and the same length, which gives each of you 15cm more width. If movement wakes you, that extra space usually helps. The UK king needs at least 2.7m x 2.9m, against 3m x 2.9m for the UK super king.
What bedding fits a Relyon Cerrado Pillowtop UK super king?
You'll need super king sheets and a 260 x 220cm duvet. The mattress is 36cm deep, so look for fitted sheets that say they suit that depth. Bedding at this size can cost noticeably more than for a UK king, so it helps to budget for it alongside the mattress.
