Key benefits

Key Benefits of the Highgrove Dawson King Size Mattress in a Box

  • Real space for two: At 75cm each for two people sharing, a couple who have outgrown a UK double get noticeably more elbow room each night.
  • Less partner disturbance: The extra width means someone getting up hours before their partner can slide out with less chance of a wake-up.
  • Length for taller sleepers: At 200cm long, it adds 10cm over a UK double, which anyone approaching six foot will feel at their ankles.
  • Rolled delivery suits king buyers: A boxed king is far easier to carry through a hallway and up a staircase than a rigid mattress of the same 5ft x 6ft 6in footprint.
  • Check specs before you order: Highgrove doesn't publish construction or firmness details for the Dawson, so ask the retailer listed on this page before committing to this size.

Who should buy the Highgrove Dawson King Size Mattress in a Box?

This size suits you if...

You share the bed every night and the UK double has started to feel cramped, one of you gets up much earlier than the other and you want to stop passing that disturbance across the mattress, or someone in the bed is approaching six foot and needs the extra length more than the extra width. Your bedroom offers at least 2.7m x 2.9m, ideally 3.2m x 3.2m.

Consider another size if...

Your room is under our suggested 2.7m x 2.9m minimum, or you sleep alone. We'd recommend the UK double instead; it keeps things affordable and leaves space to walk around the bed.

FAQ's

Frequently Asked Questions About the UK King

Is a UK king Highgrove Dawson big enough for a couple and a dog?

Usually, yes. With 75cm each for two people sharing, there's slack for a dog that settles across the foot of the bed, less if it insists on sleeping between you. If the dog is a nightly fixture and a large breed, the UK super king, 30cm wider, is the calmer option.

Will the Highgrove Dawson UK king fit in a new build master bedroom?

Often, but measure first. New build masters can feel smaller once fitted wardrobes go in. We suggest at least 2.7m x 2.9m for a king, with 3.2m x 3.2m comfortable. If your room falls short, the UK double gives back 15cm of width and 10cm of length in floor space.

Is the king size Dawson long enough for someone over six foot?

At 200cm, the UK king is 10cm longer than a UK double, and for many taller sleepers that length is the real reason to upgrade. It won't suit the very tallest, but anyone around the six foot mark should find their feet stay on the mattress rather than hanging off it.

How much wider is the king Dawson than the double?

The UK king is 15cm wider than the UK double, and you feel it every night rather than seeing it on paper. Spread across two sleepers, it's the difference between brushing elbows and turning over freely, which matters most for partners on different schedules.

What bedding do I need for the Dawson in a UK king?

Standard UK king sheets fit the 150 x 200cm footprint, paired with a 230 x 220cm king duvet. Because Highgrove doesn't publish the Dawson's depth, check with the retailer before buying fitted sheets, as shallower and deeper mattresses need different pocket depths.
