Strong & Mighty: A mattress built to last

King Koil Mighty Original Double Mattress RRP €2049 NOW €1229

The development of the ‘Mighty’ collection, exclusive to Harvey Norman, began with the collaboration of our in-house mattress designers and the King Koil team at Kaymed, based in Bluebell, Dublin and Kilcullen in Co. Kildare, which collectively employs over 300 people.

Our teams worked together on the exclusive ‘Mighty’ collection with a focus on superior support – seen through the endorsement by the International Chiropractors Association.

This select range is another example of Harvey Norman’s continued collaboration with local Irish manufacturers and producers to bring you world class mattress collections. The ‘Mighty’ collection has been created specifically for those who recognise the importance of both comfort and support.

The heavy duty open coil spring system targets areas according to comfort and support needs, while a Flex-edge support perimeter frame prevents sagging for long-lasting comfort. This is all topped off with a micro quilted, silky soft covering made from hypo-allergenic materials that repel dust mites and maintain an optimum sleep temperature. A convenient no-turn feature means occasional rotation keeps it in tip-top shape, a task made easy thanks to handles sewn around the edge.

With its seemingly endless array of features, the Mighty Endurance becomes a mattress that’s built to last.
