Key benefits

Key Benefits of the Spring King Backcare Ultimate 3000 Small Double Mattress

  • Room to sprawl on your own: At 30cm wider than the UK single, the UK small double lets a solo sleeper lie starfish on a firm, supportive surface without an arm hanging off the edge.
  • Kinder to a tight floor plan: Being 15cm narrower than the UK double, the UK small double leaves a little more floor in a box room or studio, which can decide whether the door still opens fully.
  • Easier under a sloping ceiling: In a loft conversion, the 4ft x 6ft 3in footprint makes it simpler to keep some standing room along the side you climb in from.
  • Fine for the odd shared weekend: Two guests can manage a night or two, and the independent pocket springs mean one person turning over is less likely to jolt the other.
  • Straightforward to dress: The UK small double is a standard 4ft size, so frames and fitted sheets are ordinary UK stock rather than something you need to hunt for.

Who should buy the Spring King Backcare Ultimate 3000 Small Double Mattress?

This size suits you if...

You sleep alone and want more width than a single gives you, your bedroom is compact but still allows at least 2.4m x 2.8m, or couples use your spare room only occasionally and you want firm support under them.

Consider another size if...

You share the bed every night, because a UK small double is snug for two regular sleepers. We'd recommend the UK double instead, and we suggest at least 2.6m x 2.8m for the UK double.

FAQ's

Frequently Asked Questions About the UK Small Double

Will a Backcare Ultimate 3000 UK small double fit in a box room?

It measures 120 x 190cm, or 4ft x 6ft 3in, so it suits many smaller rooms. We suggest allowing at least 2.4m x 2.8m, which leaves space to walk round the bed and open the door. Measure the door swing and any radiator before ordering, as those usually decide whether a room works.

Should I get the Backcare Ultimate 3000 in a UK small double or a UK double?

The two share the same length, and the UK small double is 15cm narrower than the UK double. Sleeping alone, the UK small double gives plenty of width. Sharing nightly, the UK double gives 67.5cm each, and we suggest at least 2.6m x 2.8m for the UK double.

Is the UK small double long enough if I'm tall?

The UK small double is 190cm long, the same as the UK single and UK double. If your feet already reach the end of a standard bed, the UK king is 10cm longer than the UK small double. We suggest at least 2.7m x 2.9m for the UK king.

Can guests share a Backcare Ultimate 3000 small double for a weekend?

For a night or two, yes. Space is tight, but the pocket springs move independently, so one guest shifting position disturbs the other less. Across the extra firm surface you also sink in less, which means couples roll towards the middle less than on a softer bed.

Is a UK small double Backcare Ultimate 3000 a good step up from a single for a teenager?

The UK small double is 30cm wider than the UK single and the same length, so it gives a growing teenager room without eating much extra floor. We suggest at least 2.4m x 2.8m for the UK small double, against 2.1m x 2.8m for the UK single. A lightly built side sleeper may find the extra firm feel too hard.
