Key benefits

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

  • Sized for typical UK bedrooms: We suggest allowing at least 2.6m x 2.8m, so the UK double sits comfortably in most master bedrooms and many second bedrooms without taking over the floor.
  • Room for two bedside tables: The UK double is 15cm narrower than the UK king, and in a modest bedroom that can decide whether you fit one bedside table or two.
  • Cushioning for closer quarters: With 67.5cm each, a medium pillow top helps you settle without nudging your partner, and Sealy says the springs won't roll you towards the middle.
  • Bedding is easy to find: Double sheets and a 200 x 200cm double duvet fit, although at 31cm deep you'll want fitted sheets with generous pockets.
  • A sensible guest room choice: If couples stay over now and then, the UK double gives them a proper shared bed while leaving space for drawers or a desk in the room.

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

This size suits you if...

You share a bed with your partner in a typical UK bedroom and want the furniture to fit around it, or you sleep alone and like space to stretch out, perhaps with a dog or cat claiming the foot of the bed.

Consider another size if...

You and your partner already feel squeezed at 67.5cm each, or either of you is tall. We'd recommend the UK king instead, provided your room allows at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Double

Is the Sealy Winslow Geltex Enhance 2400 double big enough for two people?

For most couples, yes. The UK double gives you 67.5cm each, which is the traditional amount of space for sharing in Britain. If one of you sprawls or you often wake each other, that gap is small, and the pillow top's cushioning can only do so much to make up for it.

What size bedroom do I need for a UK double Sealy Winslow mattress?

We suggest at least 2.6m x 2.8m for a UK double. Around 3m x 3m feels comfortable, giving you space to walk round the bed and open wardrobe doors. Measure with your bed frame in mind too, since a headboard or footboard adds to the footprint.

How much smaller is the Sealy Winslow UK double than the UK king?

The UK double is 15cm narrower and 10cm shorter than the UK king, which works out at 7.5cm less each for two people sharing. The UK king needs more floor space as well: we suggest at least 2.7m x 2.9m for it.

What sheets and duvet fit a Sealy Winslow UK double?

Standard double sheets fit the 135 x 190cm surface, and a 200 x 200cm double duvet covers it well. The mattress is 31cm deep, so check the pocket depth on fitted sheets before you buy, as shallower ones may struggle to stay tucked in.

Does the Sealy Winslow Geltex Enhance 2400 come in a UK small double?

Sealy lists this mattress in UK single, UK double, UK king and UK super king, so there's no UK small double option. The UK double is 15cm wider than a UK small double, which gives a couple a little more breathing room for the same length.
