What tog duvet does my child need?

Young children are less able to regulate their own body temperature meaning they are at a higher risk of overheating; therefore we recommend 4.0 tog duvets for cot beds/children under 5 years old and either 4.0 tog or medium/warm 8.0 tog duvets for singlebeds/children aged 5 years and over.

Adults would be cold under such light tog ratings but because children take up less room in their beds, the duvet is able to trap more air around their little bodies keeping them warmer.

Why do cot bed duvets only come in 4.0 tog?

The size of a cot bed is smaller and so it automatically retains more heat when the child is sleeping, an 8.0 tog duvet would be much too warm for a cot however, the larger surface area of a single bed means the child only heats the area he/she is sleeping in, so a higher 8.0 tog rating is also available on the single bed size.

Important Safety Information

Do not use in conjunction with a Baby Sleep Bag.
NEVER use a duvet or a pillow for a child under one year.
Do not exceed the maximum recommended tog duvet, 4 tog for children in cot beds and 10tog for children in single beds.
