Swapping your bedding with the seasons is one of the simplest ways to improve your sleep quality year-round. Here's your complete seasonal bedding guide. ## Spring (Tog: 7–9) As temperatures begin to rise, swap out your heavy winter duvet for a mid-weight option. Pair with breathable cotton or bamboo sheets. ## Summer (Tog: 4.5 or sheet only) A lightweight duvet or even just a flat sheet and a thin throw is all most people need. Prioritise breathable, moisture-wicking fabrics like linen or bamboo. ## Autumn (Tog: 9–10.5) Nights get cooler — it's time to bring back a medium-weight duvet. Layer with a cotton throw for flexibility as temperatures fluctuate. ## Winter (Tog: 12–13.5) Go for a high-tog duvet filled with down, wool, or a quality synthetic. Flannel or brushed cotton sheets add extra warmth and cosiness. ## The All-Season Trick Consider buying a **combination duvet** — two duvets (typically 4.5 + 9 tog) that button together to form a 13.5 tog for winter and separate for other seasons. It's a cost-effective solution that covers you all year. ## Don't Forget Your Pillows Pillow weight and fill also affect temperature. Down alternative or latex pillows tend to sleep cooler than memory foam. Stay comfortable in every season with the right bedding setup.
