The idea for Dagsmejan was born out of a personal desire to sleep better to really have the energy I want every day. I realized that while we invest in good beds and bedding, we often overlook what we wear to sleep. When I started looking into it, I found a surprising lack of innovation in sleepwear, especially compared to what we see in sportswear. Together with my co-founder Andreas Lenzhofer, we launched Dagsmejan in 2017, with the mission to redefine sleepwear through the fusion of science, nature, and design.
How did you come to the company name Dagsmejan?
Dagsmejan is an old Swedish word that refers to the last days of winter when the sun finally starts to warm the days again—it’s about transition, renewal, and balance. That felt deeply connected to our mission: helping people recharge and restore through better sleep. You can break down the name into two parts, Dag meaning day and mejan meaning power. Sleep is what gives us power for the day to come so it seemed like a perfect fit.
Why sleep? Can you say something about why sleep is so important?
Sleep is the foundation of our wellbeing—it impacts everything from our mental clarity and emotional balance to our immune function and physical recovery. Yet many of us don’t sleep as well as we could. What we wear to bed can significantly impact sleep quality by either supporting or disrupting our temperature regulation, skin comfort, and overall rest. At Dagsmejan, we want to help people sleep deeper and wake up feeling truly restored.
Tell us about your products—the science, the designs.
Our sleepwear is engineered to support the body’s natural thermoregulation at night. We’ve collaborated with leading experts and academic institutions in Switzerland and Sweden, including EMPA (the Swiss Federal Laboratories for Materials Science and Technology), to test and validate our fabrics. Each collection is designed with a specific sleep need in mind—whether it’s staying cool, staying warm, recovering after sports, or supporting sensitive skin. We use natural, high-performance fibres like eucalyptus, merino wool and beechwood, combining them with trademarked technologies. The result is breathable, feather-light sleepwear that moves with your body and helps you maintain the ideal sleep temperature all night.
What is your ambition for the company?
Our ambition is to become the global leader in sleepwear innovation—to help millions of people around the world sleep better, naturally. We want Dagsmejan to be more than just a brand; we want it to be a movement that puts sleep back at the center of wellness. By combining sustainability, science, and Scandinavian design, we believe we can transform how people think about sleep and what they wear to bed.
