Key benefits

Key Benefits of the Spring King Harmony 2000 Ortho Pillow Top Small Double Mattress

  • Room to sprawl on your own: At 30cm wider than the UK single, it gives a solo sleeper space to turn, spread out and shift position without an arm or knee hanging off the edge.
  • Fits where a double won't: Being 15cm narrower than the UK double can be the difference between a door that swings open freely and one that catches the bed frame.
  • Cushioning without a bigger footprint: The pillow top gives a softer surface to settle into, so a smaller room still gets a comfortable bed rather than a compromise mattress.
  • Ready for visiting couples: In a spare room, it takes two adults for a weekend stay, which is more flexible than a single for a room nobody sleeps in nightly.
  • Easy to dress: Small double (4ft) fitted sheets are a standard UK size, and a regular double duvet covers it with some overhang at the sides.

Who should buy the Spring King Harmony 2000 Ortho Pillow Top Small Double Mattress?

This size suits you if...

You sleep alone and have started to feel cramped on a single, or your bedroom is tight enough that a full double would crowd the floor. It also suits a spare room where a couple stays now and then but nobody shares the bed every night.

Consider another size if...

You and a partner will share the bed every night. We'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's

Frequently Asked Questions About the UK Small Double

Is the Spring King Harmony 2000 Ortho Pillow Top UK small double big enough for two?

For occasional stays, yes, and it's a sensible choice for a guest room. For nightly sharing it will feel tight, particularly if either of you moves about. The UK double gives 67.5cm each for two sharing and needs a room of at least 2.6m x 2.8m by our guidance.

What size bedroom do I need for a UK small double mattress?

We suggest at least 2.4m x 2.8m for a UK small double. That allows space to walk round the bed and open drawers. In a loft conversion with a sloping ceiling, measure the floor where you can actually stand, because the usable width beside the bed is often less than the room's full size.

Is a UK small double a good step up from a single for a teenager?

Often, yes. It's 30cm wider than the UK single and the same length, so it adds width without pushing further into the room. For a teenager who has outgrown a single but whose bedroom can't spare much floor, it gives far more room to turn over.

Should I choose the small double or double Harmony 2000 Ortho Pillow Top?

Choose the small double if you mostly sleep alone or your room is compact. The UK small double is 15cm narrower than the UK double and the same length. If a partner sleeps beside you every night, the extra width of the double is the better buy.

Will a small double Spring King mattress fit my old bed frame after downsizing?

Only if that frame is a 4ft small double. The mattress is 120 x 190cm, so a 4ft 6in double frame would leave a gap at the sides. If you're moving to a smaller room, measure the new bedroom against our suggested 2.4m x 2.8m before you buy.
