Layer Details
Euro pillowtop
A deep, quilted Euro pillowtop that adds an extra layer of ultra-cushioned comfort. It gives the surface a soft, plush feel when you first lie down.
Geltex comfort layer
Geltex is a gel-infused foam that increases comfort and body support. It sits under the pillowtop to add support beneath the soft surface.
Pocket spring support
Pocket springs are mounted in their own separate fabric pockets, so they work completely independently of one another. That lets the base respond to your body rather than moving as one piece.

Key benefits
- 90cm each for two sharing: Each sleeper gets as much width as a UK single, which means a restless partner's elbows and knees stay on their own side of the bed.
- Width that soaks up movement: Distance does more than any comfort layer to stop disturbance, and the independent pocket springs help keep each half's movement on that half.
- Room for children or pets: When a child wanders in at 3am or the dog settles at your feet, the UK super king leaves each adult a usable share rather than a narrow edge.
- 15cm more each than a UK king: Sizing up from the UK king adds 30cm of width at the same length, and that extra width is split evenly between you.
- Fills a large room properly: In a big master bedroom or a high-ceilinged period room, a UK king can look a little lost, while the UK super king suits the scale.
This size suits you if...
You share with a partner who moves a lot in the night and you want real distance between you, or children and pets regularly end up in your bed. It also suits you if your bedroom measures at least 3m x 2.9m and you like a soft, plush surface.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, or your stairs and landing are tight. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Sealy Enhance Platinum UK super king big enough for two adults and a child?
It gives two adults 90cm each, the width of a UK single per person, so a small child climbing in for part of the night can usually fit between you. Bear in mind the soft pillowtop lets bodies sink in a little, so everyone will drift slightly towards wherever the most weight sits.
How much bigger is the UK super king than the UK king Sealy Enhance Platinum?
The UK super king is 30cm wider than the UK king and exactly the same length. For two people sharing, that works out at 15cm more each: 90cm per person instead of 75cm. If length is your concern rather than width, sizing up won't help.
What size bedroom do I need for a UK super king pillow top mattress?
We suggest at least 3m x 2.9m, 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 check you can still sit up and get in and out on both sides.
What bedding fits a UK super king Sealy Enhance Platinum?
You'll need super king sheets and a 260 x 220cm duvet. The mattress is 32cm deep, so pick fitted sheets with deep enough pockets to tuck under a pillowtop. Super king bedding costs more than king, so budget for it before you buy.
Will a UK super king Sealy mattress fit through my door and up the stairs?
At 180cm wide and 32cm deep, the UK super king catches on door frames and landing turns where smaller sizes slip past. Measure the door swing, the tightest turn on the stairs and any low ceiling above them, then compare the retailers listed on this page.
