Key benefits

Key Benefits of the Relyon Sophia Pillowtop 3000 King Size Mattress

  • More room each: You each get 75cm, which is 7.5cm more per person than the UK double, so an elbow or a turn is less likely to land on your partner.
  • Length for taller sleepers: At 200cm long it is 10cm longer than the UK double, which means feet stay on the mattress rather than hanging over the end.
  • Space for early risers: If one of you gets up hours before the other, the extra width gives a little more space to slip out without rolling across your partner's side.
  • Room to prop and shift: During pregnancy or recovery, the UK king leaves space for supporting pillows on one side without pushing the other sleeper towards the edge.
  • Fits more bedrooms than a super king: We suggest at least 2.7m x 2.9m for the UK king, compared with 3m x 2.9m for the UK super king.
  • Easy bedding to find: King sheets fit, and a 230 x 220cm king duvet covers two people without a tug of war.

Who should buy the Relyon Sophia Pillowtop 3000 King Size Mattress?

This size suits you if...

You share the bed every night and wake each other more often than you'd like, or one of you is tall enough that the UK double feels short. It also suits you if a partner on a different shift needs to get up quietly, or the dog has started claiming the middle.

Consider another size if...

Your bedroom is smaller than our suggested 2.7m x 2.9m, or you mostly sleep alone. 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 Relyon Sophia Pillowtop 3000 UK king big enough for two people?

For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more per person than the UK double. That sounds modest, but you feel it at night when one of you turns over. If you both sprawl, or regularly share with a child or a dog, the UK super king gives 90cm each.

Is a UK king long enough if I'm over six foot?

The UK king is 200cm long, 10cm longer than the UK double, so length is often the real reason taller sleepers upgrade. A pillowtop adds height rather than length, so the sleeping surface stays at 200cm. If your feet currently touch the end of a UK double, the UK king is the sensible next step.

What size bedroom do I need for a UK king Relyon Sophia Pillowtop 3000?

We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m giving you comfortable room to walk round. New build master bedrooms can feel smaller once wardrobes go in, so measure from the fitted furniture rather than the bare walls. Remember to allow for the bed frame too, which adds to the 150 x 200cm footprint.

Should I get the Relyon Sophia Pillowtop 3000 in a UK king or a UK super king?

The UK king suits most couples and fits more rooms. The UK super king is 30cm wider at the same length, giving 15cm more each, but we suggest at least 3m x 2.9m for it. If partner disturbance is the main problem and your room allows it, size up. Otherwise the UK king is the balanced choice.

What bedding fits a UK king Relyon Sophia Pillowtop 3000?

Standard king sheets and a 230 x 220cm king duvet fit the UK king. Relyon doesn't publish a depth for this pillowtop, and pillowtops tend to sit taller than flat-topped mattresses, so check the depth with the seller before buying fitted sheets. Deep-pocket king sheets are the safer choice until you know.
