Key features

The Serta Perfect Sleeper range has been specially designed to combat the 5 most common sleep problems:

  1. Tossing and Turning
  2. Lack of Support
  3. Sleeping too hot or cold
  4. Partner disturbance
  5. Mattress roll-off or sag.

The range is endorsed by the Australian Physiotherapy Association, is made in Australia and comes with the Serta 90 Day Comfort Assurance.

Made in Australia

Serta Perfect Sleeper mattresses are made in Australia and are backed by a 10 year warranty, so you can be sure they will provide you with luxurious comfort for many years to come.

PRESSURE RELIEVING COMFORT A combination of our breathable Advanced Comfort Quilt and Australian Made Dunlop Foams comfort layers deliver optimal comfort to help reduce tossing & turning.

BALANCED SLEEPING TEMPERATURE Heat build-up during the night can cause uncomfortable and restless sleep. Sertas Cool Action Memory Foam combines an open cell structure with our exclusive MicroCool+ gel to significantly increase airflow and the ability to dissipate heat. It also keeps you cooler in the earlier hours of sleep to help you fall asleep.

PROPER BACK SUPPORT The SmartCoil pocket spring dual action design enhances conformability and provides independent back support. A tapered top delivers initial comfort and contouring while a barrel shaped lower section offers progressive layers of personalised support. This 5 zoned pocket coil support system assists with spinal alignment and provides support where you need it most.

UNDISTURBED SLEEP Undisturbed sleep, even when your partner moves, means you get a deeper, more restful sleep. Each SmartCoil spring is individually encased in separate fabric pockets, allowing each spring to move independently without affecting surrounding springs, while the Memory Foam comfort layers assists to absorb motion.

PREVENTS ROLL-OFF AND SAG Our Total Edge Foam Encasement helps prevent roll-off or sag, regardless of body type, size or sleeping position.

Please choose carefully. Most of our products (including manchester, beds and furniture) can’t be resold reasons once unwrapped, due to health or hygiene reasons.

If your mattress isn’t right, we’ll need to establish proof of purchase. If the product fault can be safely determined by the store who sold the product, we may offer you a refund, repair or exchange.

Where the product fault is difficult to determine by a store representative, we’ll need to speak to the manufacturer or repair agent to determine the fault and possible resolution.

Your Forty Winks store representative will be happy to liaise with the manufacturer or repair agent on your behalf to resolve the issue.

A timeline will also be provided based on the supplier location and availability of parts.

Please be aware that some of our goods are sourced offshore and may require in excess of 10 weeks to source a replacement part or product.

Unfortunately, we can’t offer a refund or exchange where the product has sustained damage due to inappropriate use, whether that’s been identified by a store representative, the product manufacturer or repair agent.

If the product doesn’t match its advertised description, your store of purchase/delivery may provide you with a refund or source a new product (if available) or similar product.
