Key benefits

Key Benefits of the Silentnight Essentials 600 Mirapocket Double Mattress

  • Room for two at a low price: The UK double gives two people sharing 67.5cm each, on independent pocket springs that keep a partner's movement on their side of the bed.
  • Fits most UK bedrooms: Allow at least 2.6m x 2.8m and you'll still have space for a wardrobe and drawers, with around 3m x 3m the comfortable norm.
  • Bedside tables on both sides: Because the UK double is 15cm narrower than the UK king, many rooms that couldn't take a king with tables both sides can manage this.
  • Easy to dress cheaply: Double sheets and a 200 x 200cm duvet are stocked everywhere at every price point, which helps if you're furnishing a whole home at once.
  • The safest guest room size: A UK double sleeps visiting couples without dominating a spare room, and this budget pocket spring model suits occasional use well.

Who should buy the Silentnight Essentials 600 Mirapocket Double Mattress?

This size suits you if...

You share the bed with a partner and want the traditional couples' size in a room that couldn't comfortably take anything bigger, you're kitting out a first flat or a whole house and need the money to stretch, or you're setting up a guest room that visiting couples can share without the mattress swallowing the space.

Consider another size if...

You and your partner both like to spread out and your room measures at least 2.7m x 2.9m. In that case we'd recommend the UK king instead, which is 15cm wider and 10cm longer than the UK double.

FAQ's

Frequently Asked Questions About the UK Double

What size room do I need for the Silentnight Essentials 600 in a UK double?

We suggest a minimum of 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves enough room to walk around the bed and open wardrobe doors. The mattress itself measures 135 x 190cm, or 4ft 6in x 6ft 3in, so most UK bedrooms, including smaller second bedrooms, can take it.

How much space does each person get on the UK double Essentials 600?

Two people sharing get 67.5cm each. That's the traditional couples' allowance in the UK, and the pocket springs help make the most of it: each spring moves independently, so you feel your own side of the bed rather than rolling towards your partner. Restless sleepers who like to starfish may still want more width.

Should I buy the Silentnight Essentials 600 in a UK double or a UK king?

The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the UK double if your room is close to our suggested 2.6m x 2.8m minimum, or if you want bedside tables on both sides in a modest room. If you have at least 2.7m x 2.9m and share every night, the UK king is the more comfortable long-term choice.

Is the UK double Essentials 600 a good guest room mattress?

Yes, arguably its best use. A UK double sleeps visiting couples, fits most spare rooms alongside a wardrobe, and this model's budget price makes sense for a bed that's used a few weekends a year. Double bedding is cheap and easy to find, which keeps the whole setup affordable.

Will a double Essentials 600 fit up narrow stairs?

At 135 x 190cm it's the largest size of this mattress that most people can turn through the stairs of an older terrace or a tight new build landing without real difficulty. Silentnight doesn't publish a weight for this mattress, so if access is genuinely awkward, measure the tightest turn before ordering and check the retailer listing.
