Key benefits

Key Benefits of the Spring King Backcare Ultimate 3000 Double Mattress

  • Shared support in a modest footprint: You get an extra firm, pocket sprung surface for two at 135 x 190cm, which means proper pushback for back sleepers without a bed that swallows the room.
  • Room left for furniture: We suggest at least 2.6m x 2.8m for a UK double, so a typical second bedroom can still fit a wardrobe and a chest of drawers alongside it.
  • Firmness each of you feels individually: The independent springs respond to each sleeper's shape separately, which helps when one partner is heavier and needs firm support the other might not notice.
  • A sensible guest room choice: Visiting couples get a genuine shared bed, and the extra firm feel suits guests who find soft mattresses leave them aching the next morning.
  • Easy to dress: Double sheets and a 200 x 200cm double duvet fit the UK double, and both are widely stocked, so you won't need to hunt for bedding.

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

This size suits you if...

You share the bed with a partner who likes a very firm surface, your bedroom needs space around the bed for bedside tables and a wardrobe, or you're furnishing a guest room where visiting couples want real support.

Consider another size if...

You and your partner sprawl, or one of you is broad across the shoulders. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Double

How much space does each person get on the Backcare Ultimate 3000 UK double?

Two people sharing the UK double get 67.5cm of width each. That is 7.5cm less each than the UK king, which gives 75cm per person. On an extra firm surface you won't sink towards each other, which helps, but restless sleepers may still find it tight.

Will a Backcare Ultimate 3000 UK double fit with bedside tables on both sides?

We suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m being the comfortable norm. Measure your room before buying: towards the smaller end, slim bedside tables on both sides can work, but you'll have less space to walk around the bed.

Backcare Ultimate 3000 UK double vs UK small double: which should I pick?

The UK double is 15cm wider than the UK small double, and both are the same length. The UK small double suits a solo sleeper or a very compact room, where we suggest at least 2.4m x 2.8m. For two adults sharing nightly, the UK double's extra width is the more comfortable option.

What are the Spring King Backcare Ultimate 3000 double dimensions in feet?

The UK double measures 135 x 190cm, which is 4ft 6in x 6ft 3in. That is the standard UK double footprint, so it should suit a bed frame sold as a UK double. Check your frame's internal measurements if it is an older or continental design.

Is the UK double long enough for a tall couple on the Backcare Ultimate 3000?

The UK double is 190cm long, which is 10cm shorter than the UK king. If either of you finds your feet reaching the end of a standard bed, the UK king adds that length as well as extra width, though we suggest at least 2.7m x 2.9m for it.
