Key Benefits of the Silentnight Aloe Vera Portloe Miracoil Ortho Double Mattress

  • Shared space that still fits the room: Two sleepers get 67.5cm each, which means room to share comfortably while leaving floor space for drawers and a wardrobe in a typical UK bedroom.
  • Less wobble from a restless partner: Silentnight's edge-to-edge design aims to limit partner disturbance, which matters more on a UK double, where you lie closer together than on a UK king.
  • Firm support for both sides: The zoned Miracoil springs shape support to different parts of the body, so each of you gets the same extra firm feel across the width.
  • Cooler when two are sharing: Breathe fibres are designed to regulate temperature, a sensible detail when two bodies share 135cm of width and the bed can warm up quickly.
  • Easy bedding to find: Double sheets and a 200 x 200cm double duvet fit, so kitting out the bed is simple, even if you're furnishing a whole home at once.

Who should buy the Silentnight Aloe Vera Portloe Miracoil Ortho Double Mattress?

This size suits you if...

You share the bed with a partner who also likes a very firm surface, your room can't take a UK king alongside bedside tables, or you're setting up a guest room where visiting couples need proper back support.

Consider another size if...

You're both broad-shouldered or restless and want more personal space each night. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m for it.

FAQ's

Frequently Asked Questions About the UK Double

Is the Silentnight Portloe Miracoil Ortho UK double big enough for two adults?

It gives 67.5cm each for two people sharing, which suits most couples who sleep fairly still. The edge-to-edge design helps here, because the firm surface stays usable right to the sides. If either of you sprawls, the UK king adds 7.5cm each and 10cm of length.

What room size do I need for a UK double Silentnight Portloe?

We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m feeling comfortable. That should leave space for bedside tables on both sides and a path to the wardrobe, though a chunky headboard or frame will eat into it.

Should I get the UK double or UK king Portloe Miracoil Ortho?

The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the UK double if your room is tight or you want space for furniture; the UK king needs at least 2.7m x 2.9m and suits taller sleepers or couples wanting more elbow room.

Will a UK double Portloe mattress get up narrow stairs?

A sprung mattress at 135cm wide can be awkward on turning stairs in older terraces or the tight landings of some new builds. Silentnight doesn't publish a depth for this mattress, so measure your stairwell and doorways first, then compare the retailers listed on this page.

Is the Portloe Miracoil Ortho double too firm for a couple who side sleep?

Possibly. It's rated extra firm, with little give at the shoulders and hips, so side sleepers may find it hard. On a UK double you also have less room to shift position than on a UK king, which can make pressure points more noticeable.
