Key benefits

Key Benefits of the Sealy Winslow Geltex Enhance 2400 Pocket Pillow Top Super King Mattress

  • Distance from a restless partner: Each sleeper gets 90cm, and Sealy says there's no roll-together, so a partner's turning stays further away from you.
  • Space when the family joins in: A small child or a dog can settle in the middle without pushing either adult towards the edge of the mattress.
  • 15cm more each than the UK king: The UK super king is 30cm wider than the UK king at the same length, so the extra room goes entirely into width.
  • Cooler with extra bodies: The open-cell Geltex layer lets air move through it, which helps when a child or pet adds warmth to an already shared bed.
  • In proportion in a large room: In a generous period master bedroom, a UK king can look slightly lost, while the UK super king fills the wall properly.

Who should buy the Sealy Winslow Geltex Enhance 2400 Pocket Pillow Top Super King Mattress?

This size suits you if...

You share with a restless partner or regularly find children or a dog in the bed by morning, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.

Consider another size if...

Your room is under our suggested 3m x 2.9m, or the bed only ever holds two adults who sleep fairly still. We'd recommend the UK king instead; allow at least 2.7m x 2.9m for it.

FAQ's

Frequently Asked Questions About the UK Super King

How much space does each person get on a UK super king Sealy Winslow Geltex Enhance 2400?

Two people sharing get 90cm each. That's 15cm more each than the UK king and 22.5cm more each than the UK double, which makes a real difference if one of you moves a lot in the night.

What size room do I need for a Sealy Winslow super king mattress?

We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once you add bedside tables. Before you order, check the door swing and any tight landing turns, because a 180cm-wide mattress is awkward to manoeuvre upstairs.

How heavy is the Sealy Winslow Geltex Enhance 2400 in a UK super king?

The UK super king weighs 63kg. Pillow tops can't be flipped, so you'll only ever rotate it, but at that weight rotating it is a two-person job. Plan for two people on delivery day too, especially in a loft conversion with a narrow staircase.

Is a UK super king big enough for two adults and a child or dog?

For occasional visits, yes. At 180cm wide, there's room for a small child or medium dog between two adults without anyone clinging to the edge. If a large dog shares every night, you'll still notice it, but far less than on a UK king.

What's the difference between the Sealy Winslow king and super king?

Both are 200cm long, but the UK super king is 30cm wider. It needs a bigger room, at least 3m x 2.9m against 2.7m x 2.9m for the UK king, and super king sheets with a 260 x 220cm duvet.
