Sonar Outlast Thermal Balancing Mattress Topper by Bambury

The Sonar® Thermal Balancing product range is designed to absorb, store and release heat while you sleep, helping you maintain optimal thermal comfort. The products feature OUTLAST® technology, which pro-actively manages heat and moisture to help provide a better, more comfortable night’s sleep. The technology, which was originally developed for NASA, is tested and proven to alleviate spikes in skin temperature that cause sleep disturbances, and can help maintain thermal compatibility between couples. OUTLAST® technology is superior in bedding products because rather than wicking away the sweat after the fact, it pro-actively manages heat and balances temperature which controls the production of moisture before it begins.

We aim to process and dispatch all orders within 1–3 business days of receiving payment. Once your order has been shipped, you will receive a confirmation email with dispatch details.

We deliver Australia-wide via Australia Post and Fastway, with signature on delivery required unless you request Authority to Leave during the checkout process. If no one is available at the time of delivery, your parcel will be taken to your local post office or collection point for pickup.

How much is delivery? 

Bed Linen

We offer free shipping Australia-wide on all orders over $150 (excluding Western Australia and the Northern Territory). Orders under $150 incur a flat rate shipping fee of $9.00.

A flat $20 shipping fee applies to all orders delivered to Western Australia (WA) and the Northern Territory (NT).

Due to high freight costs, we are unfortunately unable to ship some bulky items to regional and remote areas of WA and NT. As our products are already heavily discounted, we’re unable to absorb the additional freight charges for these locations.

If you’re unsure whether your location is affected, please contact us prior to placing your order. We are also happy to provide a freight quote upon request.

Floor Rugs

We offer Free Shipping on orders over $199.00 for all floor rugs sent to metro areas of NSW, ACT, VIC & QLD, otherwise, a $39.00 flat rate shipping fee applies.

Unfortunately we no longer ship floor rugs to South Australia, Western Australia, Tasmania and the Northern Territory.
