How to Sleep Cool During the Summer Months

As the temperatures rise so does the need for bedding that keeps you cool, comfortable, and well-rested. At Bella Casa Design Centre, we believe you shouldn't have to compromise on luxury to beat the summer heat. Whether you’re a hot sleeper or simply love the crisp feeling of breathable bedding, we’ve curated a collection from our favourite premium brands—St. Genève, Cuddle Down, SDH, and Sferra—to help you sleep beautifully all season long.

Why Bedding Matters

During the summer months, your bedding should work with your body—not against it. The key is choosing breathable, moisture-wicking, and temperature-regulating materials like linen, cotton, and lyocell. These fabrics allow for airflow and help prevent overheating, especially important for warm climates or homes without air conditioning.
