Key Benefits of the Sleepeezee Regency Knole 5600 Pocket Sprung Super King Mattress

  • 90cm each for two sharing: Each of you gets 90cm of width, which means a partner who fidgets or turns all night is far easier to sleep through.
  • 15cm more each than the UK king: The UK super king is 30cm wider than the UK king at the same length, so the extra space goes entirely into elbow room.
  • Enhanced edge support: Sleepeezee builds in enhanced edge support, which means the outer parts of that 180cm width should stay supportive when you sit or sleep near the sides.
  • Room for a child or dog: When a small child or a large dog joins you, the UK super king leaves two adults with a usable share instead of a thin strip each.
  • The width of two UK singles: At 180cm, the UK super king matches two 90cm UK singles side by side, so each of you gets the width of a single bed on one mattress.
  • Fills a grand room properly: In a period property or a generous master bedroom, a UK super king looks in proportion where a UK king can seem a little lost.

Who should buy the Sleepeezee Regency Knole 5600 Pocket Sprung Super King Mattress?

This size suits you if...

You share the bed every night with a restless partner and want distance rather than a softer surface to solve it, or children and pets often join you, and your bedroom comfortably clears our suggested 3m x 2.9m minimum.

Consider another size if...

Your bedroom is under 3m x 2.9m, or a sloping loft ceiling leaves no wall long enough. We'd recommend the UK king instead, for which we suggest at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Super King

Is the Sleepeezee Regency Knole 5600 super king big enough for two adults and a child?

The UK super king gives two adults 90cm each, so a small child climbing in at night still leaves everyone a workable share. Bear in mind the mattress is rated extra firm, and the pillow top only takes the edge off the surface, so a child used to a softer bed may find it a little unyielding.

How much bigger is the Regency Knole 5600 super king than the king?

The UK super king is 30cm wider than the UK king, and the two are the same length. For a couple, that works out at 90cm each on the UK super king against 75cm each on the UK king, so you gain 15cm of width per person.

What size bedroom do I need for a super king Regency Knole 5600?

We suggest allowing at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling more comfortable once bedside tables and wardrobe doors are in play. In a loft conversion, check the sloping ceiling first, because it often decides which wall the bed can go against.

What bedding fits a Sleepeezee Regency Knole 5600 super king?

You'll need super king sheets and a 260 x 220cm duvet. The mattress is 34cm deep, so check the fitted sheet's pocket depth on the packaging before you buy. Factor the bedding into your budget too, since replacing everything at super king size adds up.

Will a super king Regency Knole 5600 fit up my stairs?

At 180cm wide and 34cm deep, this pocket sprung mattress is a bulky item to carry through a house. Measure your front door, any landing turns and the bedroom door swing before ordering, then compare the retailers listed on this page.
