Key Benefits of the Silentnight Essentials Miracoil Ortho Small Double Mattress

  • Room to sprawl on your own: It is 30cm wider than the UK single, which means one sleeper can turn and stretch out on a firm, flat surface without ending up near the edge.
  • Fits a compact double bedroom: We suggest a room of at least 2.4m x 2.8m, so it can go into a box room or loft conversion where a UK double would crowd the wardrobe door.
  • Full double length: It shares its 190cm length with the UK double, so you give up a little width rather than legroom by choosing the smaller frame.
  • Steadier for occasional guests: The continuous springs run in head-to-toe rows, which Silentnight says prevents roll-together, a real help when a visiting couple shares the narrower width.
  • Simple to make up: At 4ft this is a standard UK size, so small double fitted sheets are easy to buy and a standard double duvet covers the 22cm depth comfortably.

Who should buy the Silentnight Essentials Miracoil Ortho Small Double Mattress?

This size suits you if...

You sleep alone and feel cramped on a single but can't spare the floor space for a full double, or you're furnishing a guest room where a couple stays now and then rather than every night.

Consider another size if...

You share a bed with a partner every night, as two adults will feel the narrower width quickly. We'd recommend the UK double instead; we suggest at least 2.6m x 2.8m for it.

FAQ's

Frequently Asked Questions About the UK Small Double

Is a UK small double Silentnight Miracoil Ortho big enough for two people?

For a couple staying a night or two, yes, and the head-to-toe spring rows help stop you drifting into the middle. For nightly sharing it is a squeeze. The UK double gives 67.5cm each for two sharing, which most couples find a more comfortable starting point.

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

We suggest at least 2.4m x 2.8m. That leaves enough space to walk round the bed and open doors in a box room or small second bedroom. If your room is tighter than this, measure where the door swings before you buy.

Is a UK small double a good upgrade for a teenager who has outgrown a single?

It can be. The UK small double is 30cm wider than the UK single but the same length, so it adds width without reaching further into the room. The Firm rating gives a flat, steady surface, although a teenager who sleeps on their side may find it a little unforgiving.

Small double or double Silentnight Miracoil Ortho for a loft conversion?

If sloping ceilings limit the space beside the bed, the UK small double is 15cm narrower than the UK double and the same length. We suggest at least 2.4m x 2.8m for the UK small double, compared with 2.6m x 2.8m for the UK double.

What bedding fits a Silentnight Miracoil Ortho UK small double?

Use small double (4ft) fitted sheets, with a standard double duvet on top for a generous overhang. The mattress is 22cm deep, so check the pocket depth on fitted sheets before buying, then compare the retailers listed on this page for the mattress itself.
