Key benefits

Key Benefits of the Spring King Backcare Ultimate 3000 King Size Mattress

  • More room each than a double: You get 75cm each, 7.5cm more per person than the UK double, which means a little more breathing space between you on a firm, flat surface.
  • Extra length for taller sleepers: The UK king is 10cm longer than the UK double, so a partner over six foot is less likely to have their feet at the very edge.
  • Less disturbance from a restless partner: Pocket springs move independently, which means an early riser getting up is less likely to jolt the person still asleep beside them.
  • Firm edge for getting in and out: The extra firm feel gives you something solid to push against when you sit up or swing your legs out, useful if you're recovering from an injury.
  • A step up that still fits most main bedrooms: We suggest at least 2.7m x 2.9m, which suits many master bedrooms that could not comfortably take a UK super king.

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

This size suits you if...

You share the bed with a partner who wants firm support, one of you is tall enough that a standard length feels short, and you keep different hours, so a mattress that limits movement across the bed matters to your sleep.

Consider another size if...

Your bedroom is smaller than 2.7m x 2.9m once wardrobes are in. We'd recommend the UK double instead, which we suggest for rooms of at least 2.6m x 2.8m.

FAQ's

Frequently Asked Questions About the UK King

Is the Backcare Ultimate 3000 UK king long enough for someone over 6ft?

At 200cm long, the UK king adds 10cm over the UK double, which is often the real upgrade for a tall partner. The extra firm surface keeps you lying on top rather than sinking, so you use the full length.

How much space does each person get on the Spring King Backcare Ultimate 3000 UK king?

Two people sharing get 75cm each. That is 7.5cm more per person than the UK double, and 15cm less each than the UK super king.

Will I feel my partner getting up early on a king size pocket spring mattress?

Less than on an open coil bed. Pocket springs react individually, and the extra space of a UK king puts a little more distance between you. A very firm surface can still carry some movement, so light sleepers may notice a partner getting up.

Should we get the Backcare Ultimate 3000 in UK king or UK super king?

The UK super king gives you 90cm each against 75cm each on the UK king, but we suggest at least 3m x 2.9m for it. The two sizes are the same length, so choose the UK super king only for extra width and a room that allows it.

Is an extra firm UK king comfortable during pregnancy?

The UK king gives you room to prop pillows and shift position without crowding your partner. The extra firm feel can press at the hip if you lie on your side, so a softer topper may help while side sleeping is unavoidable.
