Key benefits

Key Benefits of the Silentnight Mirapocket 1000 Geltex Pillow Top Double Mattress

  • Springs that suit sharing: Pocket springs respond to each sleeper separately, which means a restless partner across a shared 135cm width disturbs you less than a traditional sprung surface would.
  • Fits the average UK bedroom: At 135 x 190cm, this size leaves space for bedside tables on both sides in most rooms, where a UK king can crowd them out.
  • Softer surface for two: The pillow top with its Geltex comfort layer sits above the springs, giving both sleepers a cushioned feel across the full width of the bed.
  • Easy to dress and replace: Standard double sheets and a 200 x 200cm duvet fit this size, and both are stocked everywhere at every price.
  • A sensible guest room size: A UK double handles visiting couples comfortably, and the independent springs mean two guests unused to sharing won't feel every movement.

Who should buy the Silentnight Mirapocket 1000 Geltex Pillow Top Double Mattress?

This size suits you if...

You share the bed every night and your room sits comfortably above our suggested 2.6m x 2.8m minimum, or you sleep alone and want proper space to spread out, perhaps with a dog or cat claiming a corner. It also suits a guest room that regularly hosts couples, where the pocket springs help two people sleep undisturbed.

Consider another size if...

You and a partner both like room to sprawl, since 67.5cm each for two people sharing is a little snug for restless sleepers. We'd recommend the UK king instead, allowing at least 2.7m x 2.9m of room for it.

FAQ's

Frequently Asked Questions About the UK Double

Is the UK double Silentnight Mirapocket 1000 big enough for a couple?

For most couples, yes. It gives 67.5cm each for two people sharing, and the 1000 zoned pocket springs move independently, so you feel less of your partner's movement. It's snug if either of you sleeps spread out; in that case the UK king, 15cm wider and 10cm longer, is the safer choice.

Will the UK double fit a bedroom with bedside tables on both sides?

In most cases, yes. At 135cm wide, a UK double usually leaves room for a table each side in an average UK bedroom. We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm if you want walking space around the bed as well.

How much smaller is the UK double than the UK king in this mattress?

The UK double is 15cm narrower and 10cm shorter than the UK king. That extra width buys each sleeper more personal space, but the UK king needs a bigger room: we suggest at least 2.7m x 2.9m for it, against 2.6m x 2.8m for the UK double.

Does the pillow top make the UK double feel different for two sleepers?

The pillow top and Geltex comfort layer run across the full 135cm width, so both sleepers get the same cushioned surface. Silentnight doesn't publish the exact pillow top depth or firmness for this model, so if a specific feel matters to you, check with the retailer listed on this page before buying.

Where can I buy the Silentnight Mirapocket 1000 in a UK double?

Stockists change, so the most reliable answer is the live price table on this page, which is updated as retailers change their listings. Availability can differ between sizes of this mattress, so if the UK double shows limited options here, it's worth checking back rather than assuming it has been discontinued.
