Adjust to a high performance bed

Enjoy complete relaxation and rejuvenation with the Sealy Posturepedic Adjustable mattress range. 

Paired with a Sealy Posturematic® bed base, the Adjustable range allows you to enjoy the benefits of a bed that can be adjusted for all your therapeutic and lifestyle needs.  

Temperature Management:
  • SmarTex®, a dynamic textile treatment designed to wick away moisture and heat to give you a comfortable sleeping surface.
  • Spacer Breathable Gusset fabric helps to improve ventilation and airflow throughout the night
  • Natural wool helps to insulate the body all year round. 

Pressure Relieving Materials: 
High density comfort layers are combined with ComfortCore®, a gel infused layer that provides pressure relieving conformance to the lower back where it's needed most.

Featuring exclusive Sense & Respond Technology, designed to sense the body's weight and respond with the appropriate level of support. 

Support Technology:
  • Sealy's one-of-a-kind SRxII® titanium alloy support system is strong, resilient and durable and delivers both initial soft response and firmer deep down support.  
  • Alternating coil columns provide maximum stability to help minimise lateral movement. 
More Coils for Better Support – Additional coil density provides more hinging points for conformance and a greater supportive surface area. 

The spring unit is encased in FlexiCased® technology, a full perimeter edge support that has the ability to articulate to suit various adjustable positions. 

Specifically designed to be paired with the Adjustable mattress range is the Sealy Posturematic®  base (Sold seperately). Available in Classic and Deluxe, the Posturematic® base has a range of features including various head and foot adjustable positions.

Each Sealy Posturepedic mattress is handcrafted in Australia using locally sourced materials, and is rigorously tested to the highest industry standards.

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.
