Super King Mattresses: The Case for Going All the Way

A super king mattress at 180 x 200cm gives each person sleeping in it 90cm of width, which is exactly the same as a single bed provides one person. For couples who have spent years compromising on space, that number alone is often enough to settle the decision.

The super king is 30cm wider than a double and 30cm wider than a king, which is a substantial jump. In practical terms, it means both sleepers can move freely without disturbing each other, there is genuine room for a young child to join without anyone being pushed out, and the mattress itself has enough surface area to feel genuinely spacious rather than just adequate.

Pocket sprung super king mattresses work particularly well for couples because the larger the mattress, the more surface area over which movement can be distributed. A high spring count in a super king gives excellent point-by-point responsiveness, and the size means motion transfer is reduced further than in smaller sizes. Hybrid super king mattresses build on this with foam comfort layers that add pressure relief without sacrificing the breathability and responsiveness of springs.

Room requirements are the main practical constraint. A super king bed frame with mattress needs a room of at least 4 x 4 metres to sit without feeling oppressive, with 60cm of clearance on each accessible side as a minimum. In rooms that are just large enough, it is worth measuring and marking the full footprint on the floor before committing to the purchase.

Bedding is a practical consideration that catches people off guard. Super king bedding is not as widely stocked as king or double, so it is worth checking availability of duvet covers, fitted sheets, and mattress protectors in 180 x 200cm before buying the mattress, particularly if you have a specific brand or thread count preference.
