Layer Details
- Cool-to-touch sleep surface. The UltraGel™ cool-to-touch layer uses hyper-conductive technology woven into the surface fabric, which means the mattress feels instantly cool when you lie down. It's the feature to care about if overheating regularly wakes you.
- Gel-infused layer. This gel-infused foam responds to your movements and is 5x more breathable than standard memory foam, according to Silentnight. In practice, that means the contouring of foam with less of the heat build-up.
- Pillowtop. A pillowtop surface adds a plush, cushioned top to the mattress. It gives that sink-in, hotel-bed feel rather than a firmer sleeping surface.
- Pocket spring support system. 2000 Mirapocket® springs work independently, which means one side of the bed can move without disturbing the other. The zoning is scientifically proven, Silentnight says, to improve spinal alignment and posture.

- Room to stop noticing each other: At 90cm per sleeper, the UK super king gives each of you 15cm more width than the UK king, so a restless partner has space to turn without reaching your side.
- Springs and space working together: The 2000 Mirapocket springs move independently, and the extra width puts more distance between you, so a partner's movement has further to travel before you feel it.
- Less shared warmth in a crowded bed: If a child or dog regularly joins you, the wider surface lets bodies spread out, which helps the cool-to-touch top stay cool rather than trapping everyone's heat together.
- Soft enough for a sprawl: The medium soft pillowtop cushions shoulders and hips, which suits a family bed where side sleeping and curled-up small sleepers are the norm.
- In proportion with a large room: In a generous master bedroom or a period property with high ceilings, a 33cm pillowtop at 180cm wide fills the space the way a smaller bed would not.
This size suits you if...
You share the bed with a partner whose tossing and turning wakes you, or your children and dogs treat your bed as the family meeting point most nights, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is under 3m x 2.9m, or tight landing turns rule out a bed this wide. The UK king would suit you better, and we suggest at least 2.7m x 2.9m for it.

Is the Silentnight UltraGel Pocket 2000 super king big enough for two adults and a child?
For occasional visits, yes. The UK super king gives two adults 90cm each, so a small child can tuck in between without anyone clinging to the edge. If it happens most nights, the medium soft pillowtop will feel pleasant for a lighter child, although three bodies on a softer surface can drift slightly towards the middle.
Silentnight UltraGel super king or king for a restless partner?
If movement is what wakes you, the UK super king is the better bet. It is 30cm wider than the UK king, giving each of you 15cm more. Pocket springs reduce motion transfer, but a partner who throws out an arm or rolls a long way needs distance, and extra width supplies it.
Will a super king pillowtop mattress fit in a loft conversion bedroom?
Check the floor area first: we suggest at least 3m x 2.9m for a UK super king. Then look at where the ceiling slopes. This pillowtop is 33cm deep, so on a standard base you sit higher than on a thinner mattress, and the headboard usually belongs on the tallest wall to keep headroom when you sit up.
Does the UltraGel super king stay cool with a large dog on the bed?
Across a 180cm wide surface, you and a dog can keep some space apart, which helps the cool-to-touch fabric do its job rather than being blanketed by shared body heat. A large dog pressed against you will still warm your patch, and claws can be harder on a soft pillowtop, so a protector is sensible.
How easy is it to rotate a super king pillowtop mattress?
A pillowtop can't be flipped, so rotation is your only maintenance, and at 180 x 200cm it is a two-person job. Silentnight doesn't list a weight for this size, so clear the room before you start. You will need a clear floor area and space to lift the corners without catching the bedside tables.
