Should I buy a thick duvet?
As the nights draw in and temperatures begin to drop, many of us start wondering the same question: Do I need a thicker duvet for winter?
Before investing in one, it’s important to understand how duvet thickness, weight duvet and natural materials like wool affect warmth………and ultimately, your quality of sleep.
We hope that this guide will help you to choose the right duvet for your winter comfort, without overheating or feeling weighed down.
Should You Buy a Thick Duvet?
A common misconception is that a thicker duvet automatically means warmer. In reality, true warmth comes from the GSM (grams per square metre) and the fibre type, not just how bulky it feels. It also depends upon your room temperature and whether you are a cool or warm sleeper as it may not be necessary to change from the lightweight wool duvet you’ve been using during the summer. Wool, for example, insulates and regulates temperature; helping you stay warm without getting overheated.

Wool vs Synthetic Duvets in Winter

A thick synthetic duvet may feel warm initially, but can cause overheating and restlessness, interrupting your night’s sleep. Wool adapts to your body temperature……… keeping you snug without overheating.
How to Choose the Right Duvet for You
Ask yourself:
Does your bedroom temperature drop below 16°C in winter?
Do you sleep with the window open or heating off?
Do you often wake up feeling cold?
If you’ve answered yes to any of these - a Medium Weight is the perfect choice, or if extremely cold our substantial Extra Warm Winter wool duvet may be ideal.
If your home stays warm or you share a bed with someone who sleeps hot, a Lightweight wool duvet offers all-season comfort.
