Super King Size Mattresses

A super-king mattress, 180cm wide by 200cm long, is the generous option for couples who want genuine space to sleep. The collection covers pocket-sprung, open-coil, memory foam and hybrid constructions from Hypnos, Vispring, Tempur and Heal's own mattress specialists, with firmness options calibrated for different sleeping positions.

A super-king mattress measures 180cm wide by 200cm long, 30cm wider than a standard king. The extra width gives each sleeper roughly the space of a single bed, which is particularly useful for couples who move during sleep or co-sleep with young children.

Pocket-sprung constructions isolate movement between sides better than open-coil, which matters when one partner moves and the other is a light sleeper. Hybrid pocket-and-foam designs take this further, combining spring responsiveness with foam pressure relief.

Firmness depends on weight and sleeping position rather than bed size, side sleepers generally prefer medium-soft, back sleepers medium-firm, stomach sleepers firm. Split-firmness options (different firmness each side) are available on some models for couples with different preferences.

A quality mattress is engineered for 8-12 years of daily use, with the natural-filling models at the top of the range lasting longer. Rotate the mattress every three months for the first year, then every six months, this evens out wear considerably.
