Duvet tog ratings
Young children can overheat so if they are old enough to use a full size bed, we recommend using a single size 4.5 tog duvet.
| Tog rating | Season / heat | Feel |
| 2.5 tog | High summer / hot sleepers | Light thermal insulation |
| 4.5 tog | Summer | Lower thermal insulation |
| 9 tog | Spring & Autumn | Cosy medium heat |
| All season 13.5 tog | 4.5 tog + 9 tog | Very warm |
| All season 11.5 tog | 2.5 tog + 9 tog | Warm |
| All season 7 tog | 2.5 tog + 4.5 tog | Lower warmth |
