Generously deep & extra wide, the Highgrove Coolmax Memory has been specifically designed to suit IKEA king size beds that measure 160cm wide & 200cm long. Coolmax is an innovative fabric that dissipates perspiration away from the body & through the fabric where it can evaporate quickly, resulting in cooler & fresher night's sleep. The memory foam layer is temperature sensitive, designed to soften when it comes into contact with warm surfaces & moulds itself to the sleeper’s body shape. This reduces the pressure points on your body, creating better blood circulation & resulting in less tossing & turning by evenly distributing your body weight. The mattress has a sturdy open coil interior, a system made up of hourglass shaped springs connected into one single unit by a spiral wire, also known as a helical wire. To further strengthen the unit, a thick rod edge wire is attached to the perimeter of the spring interior. This wire prevents border breakdown & allows you the full use of the mattress width. One sided, the mattress does not need to be flipped over, but it is recommended that you rotate it regularly from head to toe. This will enhance its lifespan & help to even out its wear & tear. Manufactured to European bed sizes, the Coolmax Memory mattress is upholstered in a soft to touch knitted stretch fabric cover & offers a medium & comfortable support.
