Key benefits

Key Benefits of the Dreams Workshop Simmonds Traditional Spring King Size Mattress

  • More room each than a double: Each of you gets 75cm, which is 7.5cm more than the UK double gives, so elbows and knees meet less often during the night.
  • Length for taller partners: At 200cm long, the UK king is 10cm longer than the UK double, which means a tall sleeper is less likely to have feet hanging over the end.
  • Space for early starters: If one of you leaves hours before the other, the wider surface gives the person getting up room to slide out without rolling across their partner.
  • Room to prop and shift: During pregnancy or recovery, there's space for a wedge or extra pillows on one side while the other sleeper keeps a usable half.
  • Easy imperial check: In imperial, the UK king measures 5ft x 6ft 6in, handy if your bed frame or headboard was sold in feet and inches.
  • Standard king bedding fits: King sheets and a 230 x 220cm king duvet fit the UK king, so you won't need anything specialist to dress the bed.

Who should buy the Dreams Workshop Simmonds Traditional Spring King Size Mattress?

This size suits you if...

You share the bed every night and keep bumping into each other on a UK double, or one of you is approaching 6ft and wants the extra length. It also suits couples on different schedules, where one leaves hours before the other.

Consider another size if...

Your bedroom is smaller than our suggested 2.7m x 2.9m. 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 Dreams Workshop Simmonds UK king big enough for two people?

For most couples, yes. The UK king gives 75cm each, which is 7.5cm more per person than the UK double. That extra space helps if one of you sprawls, or if a dog regularly claims part of the bed.

Is the Simmonds UK king long enough if you're over 6ft?

The UK king is 200cm long, 10cm longer than the UK double. That's a real relief for anyone approaching 6ft, because it gives your feet somewhere to go instead of over the end. If height is your main reason for upgrading, length is the more useful gain than width.

What size bedroom do I need for a UK king Simmonds mattress?

We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m giving comfortable room to move. New build master bedrooms can feel tighter once wardrobes go in, so measure from the wardrobe doors, then compare the retailers listed on this page.

Does the Dreams Workshop Simmonds come in a size bigger than a UK king?

No. The Simmonds isn't made in a UK super king, so the UK king is the largest size available. If you want the 90cm each that a UK super king would give two sharers, you'd need to look at a different mattress.

What sheets and duvet fit a Simmonds king size mattress?

Standard king sheets fit the UK king, along with a 230 x 220cm king duvet. Bedding from a UK double won't stretch to it, so plan to replace your sheets when you upgrade.
