The Impact of Mammoth Mattress Technology on Objective and Subjective Sleep in Good Sleepers

Dr Jason Ellis (PhD, CPsychol) – February 2012

Sleep is a fundamental life process which confers benefits for optimal physical and psychological functioning. It has been long established that the bedroom environment has a powerful impact on an individual’s perceptions of their sleep and the quality, quantity, and timing of the sleep they obtain. To that end, clinicians, when addressing sleep in a therapeutic context will often ask specific questions about the bedroom environment and, if necessary, enable changes in order to maximise the potential for efficient, healthy, sleep. Such questions about the bedroom environment usually involve the influence of external factors on the bedroom (i.e. levels of ambient light and noise and the temperature in the bedroom) and more specifically the make-up of the bed itself (i.e. pillows, mattress, and bedding).

The aim of the scientific study was to determine whether using a Mammoth mattress resulted in increased sleep performance both subjectively and objectively compared to a typical night of sleep at home with their current mattress.

In sleep trials Mammoth’s Medical Grade™ foam has been proven to deliver a better night’s sleep.
