This can be boiled down to three wonderful qualities of cotton. Breathability - as a natural fabric, cotton is very breathable and can help regulate your body temperature at night, keeping you cool in summer and cosy in winter.
Soft and hypoallergenic - cotton's natural soft fibres also make it a great choice for sensitive skin and peaceful sleep. Low maintenance - machine washable, and okay to pop in the tumble dryer, we love anything that involves fuss-free care.
