Key benefits

Key Benefits of the Silentnight Yours & Mine King Size Mattress

  • More space each than a UK double: You each get 7.5cm more width than on a UK double, which means a little more distance between you when one of you shifts position in the night.
  • Extra length for taller sleepers: At 200cm it is 10cm longer than a UK double, so a partner nearing 6ft can stretch out without their feet ending up over the edge.
  • Fewer disturbances on split schedules: If one of you is up hours before the other, the extra width gives the person leaving room to slip out without rolling straight into the person still asleep.
  • Room for pillows and changing positions: During pregnancy and the months after, the UK king gives you space to prop pillows around you and turn over without taking over your partner's half.
  • Easier fit than a UK super king: We suggest allowing at least 2.7m x 2.9m for the UK king, which is easier to manage in a typical master bedroom than a UK super king.

Who should buy the Silentnight Yours & Mine King Size Mattress?

This size suits you if...

You share the bed every night and wake each other up more than you'd like, one of you is close to 6ft and finds the end of a UK double too near, or you need room to arrange support pillows without squeezing your partner.

Consider another size if...

Your bedroom is smaller than our suggested 2.7m x 2.9m once wardrobes and bedside tables are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's

Frequently Asked Questions About the UK King

Is the Silentnight Yours & Mine UK king long enough for someone over 6ft?

It is 200cm long, which is 10cm longer than the UK double version, so a partner close to 6ft has more room at the foot. Very tall sleepers should still measure from head to toe and compare that with the 200cm length before choosing.

How much space does each person get on a UK king Yours & Mine?

Two people sharing get 75cm of width each. That is 7.5cm more each than the UK double, enough to give you a little more distance from a partner who turns over a lot or gets up early.

What size bedroom do I need for a Silentnight Yours & Mine king size?

We suggest at least 2.7m x 2.9m, and 3.2m x 3.2m if you want room to move around comfortably. New build bedrooms can feel smaller once fitted wardrobes are in, so measure the floor space you'll actually have free.

Should I get the Yours & Mine in a UK king or a UK super king?

The UK king is 30cm narrower than the UK super king and the same length, giving you 15cm less width each. If a dog regularly sleeps on the bed and you have at least 3m x 2.9m of floor space, the UK super king may suit you better.

What bedding fits the Silentnight Yours & Mine in a UK king?

Standard king sheets fit, along with a 230 x 220cm king duvet. Silentnight doesn't publish a depth for this mattress, so check the pocket depth of any fitted sheet against the mattress once it arrives.
