We spend roughly a third of our lives asleep, yet the bedroom is often the last room we design with care.

Research consistently points to three environmental factors that shape sleep quality: light, temperature and sound.

Darkness first

Even small amounts of light can suppress melatonin. Blackout lining, a dimmable warm lamp and removing standby LEDs make a measurable difference.

Keep it cool

Most people sleep best when the room is cooler than the rest of the home. Breathable bedding in linen or cotton helps regulate temperature through the night.

Soften the sound

Textiles absorb noise. Curtains, an upholstered headboard and a rug can quieten a bedroom more than you might expect.
