Introducing iSeries

Crafted right here in New Zealand, the iSeries mattress combines innovative comfort with trusted support and durability. Made with high-quality Kiwi materials, it offers a perfectly balanced way to upgrade your sleep. And even better: it’s delivered rolled and boxed, right to your bedroom.

Personalised Support
The secret to the iSeries's perfect balance of comfort and support lies in its core, which combines NZ-made foam with individually wrapped pocket springs. The iSeries conforms to your unique body shape and weight distribution, ensuring personalised support for proper spinal alignment, minimising pressure points and providing a more restful sleep for all body types.
Minimised Sleep Disturbance
Sharing a bed shouldn't mean sacrificing a good night's sleep. iSeries' combination of independent pocket springs and foams effectively absorbs and minimises movement across the mattress. Whether you sleep with a partner, the kids, or the family dog, the iSeries is designed to give you a more peaceful night.
Serta-fied Comfort
Whether your preference is for a Plush or Medium feel, the iSeries has the comfort you need. The breathable quilted top layer features optimal airflow for comfort throughout the night, while the Serta-fied NZ-made foam layer is especially designed to cradle your body for a truly restful sleep experience.

Frequently Asked Questions

  • How do I unpack my Serta iSeries Mattress?

    Unpack your iSeries Mattress in four easy steps.

    1. With help, lay the box on its side.

    2. Remove your iSeries mattress from the box.

    3. Carefully snip and tear away the surround while making sure not to cut your mattress. *Take care when unwrapping your mattress as it may unroll itself quickly once released.

    4. Your mattress will be ready in minutes but may take up to 72 hours to fully recover from being compressed.

  • Do I need to flip my mattress?

    We recommend you rotate your mattress every 2 weeks for the first 3 months, then rotate every 3 months after that.

  • When should I replace my mattress?

    While a good quality mattress should last 8-10 years, you may need to replace your mattress more frequently as your sleep requirements change.

    Over time, you may find that you’re not getting the same quality of sleep you used to. Changes in sleep quality can be due to wear and tear on your mattress but can also be due to physiological changes or changes in your sleep environment.

    If your mattress is less than 8-10 years old and you’re not sleeping as well as you used to, it might be time to investigate a new mattress that better fits your needs.

  • Can I put the iSeries Mattress back in its box?

    Unfortunately, once released from the packaging, it cannot be re-compressed back into the box.

  • Is there a warranty on iSeries mattresses?

    Yes there is! Rest easy with a 5 year warranty on the iSeries range.
