Key Benefits of the Sealy Perfection Plush Double Mattress

  • Fits the typical UK bedroom: At 135 x 190cm (4ft 6in x 6ft 3in) it leaves space for wardrobes and drawers in rooms where a UK king would dominate.
  • Edge support matters more at this width: With 67.5cm each for two people sharing, Sealy's Unicased edges firm up the sides so you can use every centimetre without feeling perched.
  • Room for bedside tables both sides: In a room around our suggested 2.6m x 2.8m minimum, a UK double usually still allows a bedside table each, which a larger size often rules out.
  • Bedding is easy and cheap to find: Double sheets and a 200 x 200cm duvet are stocked everywhere, so dressing this size costs less than kitting out a UK king or super king.
  • A sensible guest room choice: The medium feel suits most sleeping positions, which means visiting couples of different builds and habits are all reasonably well served.

Who should buy the Sealy Perfection Plush Double Mattress?

This size suits you if...

You share the bed every night and your room sits around the typical UK size, where a UK king would leave you squeezing past the footboard. It also suits a guest room that hosts visiting couples, since the medium feel accommodates most sleepers. Solo sleepers who like to spread out, or who share with a dog claiming a corner, will find the 135cm width generous without swallowing the room.

Consider another size if...

You're a couple with the room to go bigger, since 67.5cm each is workable but snug on an open coil system that transfers some movement. The UK king is 15cm wider and 10cm longer; we suggest at least 2.7m x 2.9m for it.

FAQ's

Frequently Asked Questions About the UK Double

Is a UK double Sealy Perfection Plush big enough for two people?

Yes, though it's the compact end of comfortable. Two people sharing get 67.5cm each, roughly the width of a cot each, so you will notice a partner more than on a UK king. The Unicased edge support helps here, keeping the sides firm so neither of you loses usable width at the edge of the bed.

What room size do I need for the Sealy Perfection Plush double?

We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That's our guidance rather than Sealy's, and it allows for walking space and, in most layouts, a bedside table on both sides. If your room is tighter than that, measure carefully before committing to this size.

Should a couple choose the double or the king in this mattress?

It comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, and because this mattress uses open coils that move more as a unit, couples who are easily disturbed may prefer the extra width. If your room meets our suggested 2.7m x 2.9m for the UK king, sizing up is worth considering.

Will the double size fit up narrow stairs in an older terrace?

At 135cm wide it's the largest size that turns most tight staircases without drama, one reason the UK double remains the default in older terraced homes. Sealy doesn't publish a weight for this mattress, so if your landing is especially awkward, check access with the retailer before you order.

Is the Sealy Perfection Plush double a good choice for a guest room?

It's well suited to one. The medium feel avoids extremes, so visiting couples with different preferences should both find it agreeable, and the 135 x 190cm footprint leaves space for a wardrobe and drawers in a typical second bedroom. Standard double bedding keeps the spare linen cupboard simple too.
