Quality sleep is the key to a healthy lifestyle, so choosing the right mattress is important for a great nights slumber! The King Koil, King size Quartet is proudly Australian made and has been designed using the latest innovations and quality foams and fabrics to deliver a Firm Feel mattress that is a result of years of research and advanced sleep technology. Approved by the experts, King Koil is recognised as leading mattress brand that offers exceptional spinal support what-ever your shape or size. Relax and recharge thanks to the Reflex Max Support System with Variable Response Springs (VRS) which feature additional turns at the top of the spring that dynamically respond to your body and provide greater conformance and comfort, whilst minimising motion transfer. Each spring is individually enclosed in a perforated casing allowing for increased breathability and a healthier sleep environment. The AeroComfort layers are a combination of AeroQuilt/AeroLatex/AeroFoam/AeroWeb and Gel infused memory foam that helps absorbs heat and stabilise temperature control, aiding in a more hygienic sleep experience by controlling the spread of common allergens and dust mites. The King Koil Quartet mattress comes with a 10 year manufacturer's warranty and is available in a Firm, Medium or Plush feel to suit your preferred comfort level. This mattress is also Endorsed by The International Chiropractors Association and approved by the National Asthma Council to carry the Sensitive Choice butterfly symbol so you can breathe and sleep easy!
