Cambridge Sleep Sciences
Cambridge Sleep Sciences Ltd, is a legacy Life Sciences investment of which Roadside Real Estate plc holds a 42.8% interest. CSS develops technology which improves natural sleep. Using the principles of neuroscience and cutting-edge technology to enhance brain activity during sleep, its innovative solutions aim to improve health, wellbeing and enhance quality of life.
Its SleepEngine® technology has been developed and refined over a decade by a team of researchers, scientists, sound engineers and medical experts. This unique technology produces sounds which emulate the waves created by the brain during sleep cycles. The sleep sounds guide the user’s brain through the sequence of healthy sleep cycles, helping them fall asleep and achieve the quality of sleep they need in a consistent and optimal way.
In June 2025, the Company signed a put option agreement with CGV Ventures 1 Ltd that will enable the Company to realise a minimum of £48 million from the future sale of its 48.2% interest in Cambridge Sleep Sciences Ltd.
