Layer Details
Pillowtop
Additional layers of upholstered filling that create a softer, more comfortable surface. It takes the edge off the medium-to-firm feel without changing the rating.
Gel layer
A cooling gel-infused layer designed to dissipate excess body heat. That should help you stay more comfortable if you sleep warm.
Pocket springs
Rows of small-diameter pocket springs, each wrapped in its own cloth sleeve. Each spring works independently, so the support follows your body more closely.
Foam encapsulated border
A high-density foam border around the edge of the spring system. It gives edge-to-edge support, so the sides feel steadier when you sit or sleep near them.

Key benefits
- Room to get away from a restless partner: Each of you gets 90cm of width, 15cm more each than the UK king, so a partner who fidgets all night is simply further away from you.
- Springs that move on their own: The pocket springs are individually wrapped and work independently, which means a turn on one side should travel less across the wide surface to the other.
- Steadier edges when the bed is crowded: A high-density foam border runs round the spring unit, so a child or dog pushing you towards the side still leaves you a firm edge to lie on.
- Cooling for a busier bed: Two adults plus a child or pet make for a warm bed, and the gel-infused layer on top is designed to draw away excess body heat.
- Extra width without extra length: The UK super king is 30cm wider than the UK king but the same length, so it suits a room with spare width rather than spare depth.
- A cushioned top over firm support: The pillowtop softens the surface of a medium firm mattress, which gives a gentler first feel across the whole 180cm width.
This size suits you if...
You share with a partner whose tossing and turning keeps waking you, or your children and dog regularly end up in the bed by morning. It also fits if your main bedroom is a large one, perhaps in a period house, where a smaller bed would look lost against the wall.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m and still gives 75cm each.

FAQ's
How much space does each person get on the Sweet Dreams Lumina Pillowtop UK super king?
Two people sharing get 90cm each on the UK super king. That is 15cm more each than the UK king and 22.5cm more each than the UK double, which is the difference a light sleeper next to a restless partner will feel most.
What size bedroom do I need for a UK super king Lumina Gel Pocket 1000 Pillowtop?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once bedside tables and wardrobe doors are in. In a loft conversion, measure where the ceiling slopes, because the bed may only fit against one wall with enough headroom to get in and out.
Is the Lumina Pillowtop super king big enough for a family sharing with a child?
It gives the most width of any standard UK size, at 180cm across. If a young child joins you most nights, the extra room over a UK king means everyone keeps a share, and the foam border helps whoever ends up near the edge feel more secure.
UK king or UK super king in the Sweet Dreams Lumina Pillowtop?
The UK super king is 30cm wider than the UK king and the same length. Choose the UK super king if your room allows at least 3m x 2.9m and you want distance from a restless sleeper; the UK king needs at least 2.7m x 2.9m.
What should I check before ordering a super king mattress for an upstairs room?
Measure the bedroom door swing, the stair turns and the landing, as a mattress 6ft wide is the hardest size to manoeuvre in older houses. Budget for super king sheets and a 260 x 220cm duvet too, and choose fitted sheets that suit the 32cm depth.
