Key benefits

Key Benefits of the Silentnight Essentials Miracoil Ortho Single Mattress

  • Leaves room for everything else: At 90cm wide, a UK single leaves floor space for a wardrobe, a desk and toy storage, and we suggest at least 2.1m x 2.8m of room.
  • Fits standard raised frames: The UK single is the standard size for bunks, cabin beds and mid sleepers, although you should check the 22cm depth against your frame's guidance on rail height.
  • Steady support for one back sleeper: It's rated firm, which means a flat, even surface that keeps a growing child or a teen who sleeps on their back from sinking in.
  • Easy bedding to find: Standard single sheets fit, along with a single duvet at 135 x 200cm, so replacing bedding for a child's room or guest bed is simple.
  • Suits a spare room that doubles as an office: A UK single can sit along one wall under a sloping loft ceiling or beside a desk, and the room still works during the day.

Who should buy the Silentnight Essentials Miracoil Ortho Single Mattress?

This size suits you if...

You're buying for a child, teen or single adult who sleeps mostly on their back and likes a firm surface. It also suits you if the bed is going on a bunk, cabin bed or mid sleeper, or into a compact spare room that has to fit a desk too.

Consider another size if...

Two people will share it, or a lone sleeper likes to spread out. The UK small double would suit you better; we suggest at least 2.4m x 2.8m for the UK small double.

FAQ's

Frequently Asked Questions About the UK Single

Will the Silentnight Miracoil Ortho UK single fit a bunk bed or mid sleeper?

At 90 x 190cm, the UK single matches the standard size for most bunks, cabin beds and mid sleepers. The mattress is 22cm deep, so check the frame maker's maximum mattress depth before buying. That limit keeps enough guard rail above the sleeping surface for a child, so it matters more than the width.

Is a UK single Miracoil Ortho long enough for a tall teenager?

The UK single is 190cm long, or 6ft 3in. The UK small double and the UK double are the same length, so sizing up to either only adds width. If your teen is already very tall, the UK king is 10cm longer than the UK single and is the length to look at.

What room size do I need for a Silentnight Miracoil Ortho single?

We suggest at least 2.1m x 2.8m for a UK single. That leaves space to walk around the bed and open a wardrobe in a child's room or a small spare room. A bedroom under a sloping loft ceiling can also work, as long as the bed sits along the full-height wall.

Should I choose a UK single or UK small double Miracoil Ortho for a guest room?

The UK single is 30cm narrower than the UK small double, and both are the same length. A UK single suits a room that also has to work as a study or office. If adult guests stay often, the UK small double gives them more room, and we suggest at least 2.4m x 2.8m for the UK small double.

What bedding fits a Silentnight Essentials Miracoil Ortho UK single?

Standard single fitted sheets fit the 90 x 190cm UK single, and a single duvet at 135 x 200cm covers it comfortably. Single bedding is the easiest size to find in the UK, so spare sets for a child's room or guest bed are simple to pick up.
