Key benefits

Key Benefits of the Silentnight Athens 1400 Mirapocket Ortho Super King Mattress

  • 90cm of space each: With 90cm each for two people sharing, you can both stretch out fully without negotiating over the middle of the bed.
  • Distance from a restless partner: Pocket springs move independently, and at this width the extra distance does as much as the springs to keep a fidgeting partner from waking you.
  • Room for the whole household: If children or a large dog treat your bed as theirs, the 6ft width means everyone still gets a workable share.
  • A firm surface across the full width: The firm ortho feel stays consistent edge to edge, useful when a child perched near the side would sink into a softer mattress.
  • 30cm more than a UK king: The UK super king is 30cm wider than the UK king at the same length, a noticeable difference for two adults who both like space.

Who should buy the Silentnight Athens 1400 Mirapocket Ortho 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 restless and you have found that distance works better than any comfort layer, or children and pets regularly join you and a UK king has started to feel crowded. You should also prefer a firm, supportive feel, since the Athens 1400 only comes in this ortho firmness.

Consider another size if...

Your bedroom falls short of the 3m x 2.9m we suggest as a minimum for a UK super king. The UK double would suit you better; allow at least 2.6m x 2.8m for that size.

FAQ's

Frequently Asked Questions About the UK Super King

Is a super king too big for my bedroom?

For a UK super king we suggest a room of at least 3m x 2.9m, and around 3.5m x 3.2m feels more comfortable, leaving space to walk round both sides and open wardrobe doors. Measure with the door swing in mind. If your room is smaller, the UK double needs at least 2.6m x 2.8m.

How much space do two people get on the Athens 1400 super king?

90cm each for two people sharing, the same width per person as a UK single. That matters with a firm mattress like this one: you feel less partner movement through pocket springs anyway, and the extra distance reduces it further, so a restless sleeper next to you is much easier to ignore.

Is the super king worth it over the king for this mattress?

The UK super king is 30cm wider than the UK king, and the two are the same length. If children wander in at night or a dog shares as routine, that extra width is the difference between everyone fitting and someone decamping. If it's just the two of you and space is tight, the UK king still works well.

Will the Athens 1400 super king get up my stairs?

A 180 x 200cm pocket spring mattress is a genuinely awkward carry, and unlike foam mattresses it cannot be bent or rolled. Measure your stairwell, landing turns and bedroom door before ordering. Silentnight doesn't publish a weight for this size, so plan for two people to move it.

What bedding does the super king size take?

Super king fitted sheets for the 180 x 200cm footprint, and we'd pair it with a 260 x 220cm duvet so the covers reach both sides properly. Bedding at this size costs more than double or king equivalents, so it's slightly higher running cost to factor in alongside the mattress itself.
