King Mattresses Auckland — Simply Beds NZ

A king mattress is the ultimate upgrade for couples who value space, or for anyone who simply refuses to compromise on room to sleep. Measuring 1650mm wide x 2030mm long, a king gives you and your partner genuine space to sleep without disturbing each other — and transforms any master bedroom into the retreat it deserves to be.

What size is a king mattress in NZ?

A standard NZ king mattress measures 1650mm wide x 2030mm long — 150mm wider than a queen and a full 300mm wider than a double. If you've ever woken up clinging to the edge of the bed, a king is the solution. It's also worth noting that a king mattress requires a king base and king-sized linen, so it's worth factoring those into your planning.

Which king mattress is right for me?

Our king range includes a mix of pocket spring and memory foam options across a variety of feels, so there's a genuine match for every sleep style and budget. The Raglan is available in firm, medium, and plush — a versatile, well-supported option suited to most sleepers. The Venice comes in medium and plush for those who prefer a softer, more cushioned feel. For something truly special, the Naturally Merino range offers firm, medium, plush, and ultra plush — crafted with natural merino wool for outstanding temperature regulation and year-round comfort. The Sierra rounds out the range as a reliable all-round choice.

As a general guide: back sleepers tend to suit firm or medium for spinal support; side sleepers often do better on medium or plush for pressure relief at the hips and shoulders; and those who love a truly luxurious feel will find it in the Naturally Merino ultra plush.
