Key benefits

Key Benefits of the Hypnos Legacy 3 Medium Super King Mattress

  • 90cm each, every night: Two people sharing get 90cm each, which means you can both change position freely without ever meeting in the middle.
  • Distance plus motion isolation: Pocket springs absorb movement locally, and at this width your partner's tossing happens far enough away that little of it reaches you anyway.
  • Space for night-time visitors: When a child pads in at 3am, or the dog treats your bed as their own, a 6ft width means nobody ends up clinging to the edge.
  • 30cm wider than a UK king: The UK super king is 30cm wider than the UK king and the same length, and that extra width is where the sense of luxury comes from.
  • Fills a large master properly: In a period property or generous new build master, a smaller bed can look lost; at 6ft x 6ft 6in this one anchors the room.

Who should buy the Hypnos Legacy 3 Medium Super King Mattress?

This size suits you if...

You share the bed every night and want the most sleeping space a standard UK size offers, your partner is genuinely restless and you'd rather buy distance than hope a comfort layer fixes it, or children and pets regularly join you and everyone still needs their share. Your bedroom should measure at least 3m x 2.9m by our guidance, with around 3.5m x 3.2m feeling more comfortable.

Consider another size if...

Your bedroom is under our suggested 3m x 2.9m minimum, or the bed would dominate the space once wardrobes and doors are accounted for. We'd recommend the UK king instead, where we suggest at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Super King

Is the Hypnos Legacy 3 available in a UK super king?

Yes. The Hypnos Legacy 3 Medium comes in a UK super king measuring 180 x 200cm, or 6ft x 6ft 6in. It's the largest of the four sizes offered, alongside the UK single, UK double and UK king. Compare the retailers listed on this page for current pricing, as the figures shown are updated as retailers change them.

How much space do two people get on the super king Hypnos Legacy 3?

Two people sharing get 90cm each. That's a generous personal zone, and combined with the pocket spring construction, which limits how far movement travels across the surface, it makes this size a sensible pick if one of you is a light sleeper and the other shifts around a lot.

What room size do I need for the Hypnos Legacy 3 in a UK super king?

We suggest a minimum of 3m x 2.9m, with around 3.5m x 3.2m feeling right once you add bedside tables on both sides and space to walk around. Before ordering, check the practical snags at this size too: door swing, tight landing turns and whether the mattress can make it up your stairs.

Should I get the Hypnos Legacy 3 in a UK king or super king?

The UK super king is 30cm wider than the UK king and the same length, so the question is width and room size. If your bedroom meets our suggested 3m x 2.9m minimum and you share with a restless partner, children or pets, the extra width is what you'll notice. Tighter rooms suit the UK king, where we suggest at least 2.7m x 2.9m.

What bedding does the super king Hypnos Legacy 3 take?

Standard UK super king sheets fit the 180 x 200cm mattress, and a 260 x 220cm duvet is the usual pairing. Budget for the bigger bedding when comparing sizes: super king linen costs more than UK king equivalents, and it's an ongoing expense rather than a one-off, so it's sensible to factor in before you commit.
