Bambury Mattress Topper

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.
