Key benefits

Key Benefits of the Silentnight Aloe Vera Polperro Miracoil Memory Double Mattress

  • Shared space that fits real rooms: At 135 x 190cm, the UK double gives each of you 67.5cm, and we suggest a room of at least 2.6m x 2.8m.
  • Space left for bedside tables: In a room around 3m x 3m, a UK double usually leaves enough floor for a bedside table on each side, so neither of you has to climb over the other.
  • Less disturbance when space is tight: Silentnight describes the edge-to-edge design as minimising partner disturbance, which matters more on a UK double where you sleep closer together than on bigger sizes.
  • A medium feel for two different sleepers: Silentnight rates it medium and says it suits all sleep positions, a reasonable middle ground when one of you sleeps on your side and the other on your back.
  • Bedding that is easy to find: Double sheets are sold almost everywhere, and a 200 x 200cm double duvet fits, so kitting out the bed won't send you hunting for unusual sizes.

Who should buy the Silentnight Aloe Vera Polperro Miracoil Memory Double Mattress?

This size suits you if...

You share a bed every night in a typical UK bedroom of at least 2.6m x 2.8m, and you'd rather keep floor space for furniture than have the widest possible mattress. It also fits a guest room where visiting couples stay a few nights.

Consider another size if...

One of you is tall, or you both sprawl, and your room meets our suggested 2.7m x 2.9m. We'd recommend the UK king instead, which is 10cm longer.

FAQ's

Frequently Asked Questions About the UK Double

What size bedroom do I need for a Silentnight Polperro Miracoil Memory UK double?

We suggest at least 2.6m x 2.8m for a UK double. Around 3m x 3m is more comfortable, as it usually leaves room to walk round the bed and fit bedside tables. Before you order, measure the stairs and landing too, then compare the retailers listed on this page.

Is a UK double big enough for two people to share?

For most couples, yes. A UK double gives each of you 67.5cm of width, which is enough if you sleep fairly still. Yes, it's a closer fit than larger sizes, but Silentnight's edge-to-edge design is described as minimising partner disturbance, which may help if one of you is restless.

Should I choose the UK double or UK king Silentnight Polperro Miracoil Memory?

The UK double is 15cm narrower and 10cm shorter than the UK king, so you each get 7.5cm less width. If your room meets our suggested 2.7m x 2.9m for the UK king and either of you is tall, size up. Otherwise the UK double keeps your room usable.

What bedding fits a UK double Silentnight mattress?

Standard double fitted sheets suit the 135 x 190cm footprint, and a 200 x 200cm double duvet fits. The mattress is 28cm deep, so check that the fitted sheet you choose is made for deeper mattresses before buying.

How big is a UK double mattress in feet and inches?

A UK double is 4ft 6in x 6ft 3in, or 135 x 190cm. It's 15cm wider than the UK small double and the same length, so if you're replacing a UK small double, you gain width without needing a longer room.
