SIJO Delivers Better Sleep Through Thoughtful Materials

There’s a moment a lot of people reach — usually somewhere in the thick of a demanding job, a packed schedule and too many restless nights — where sleep stops feeling like a given and starts feeling essential.
That’s where SIJO began.
Founders Anni Stromfeld and Jacob Xi arrived at a realization that feels simple in hindsight: overall wellness isn’t built from grand gestures. It’s made up of small, intentional decisions about everyday things, including what you sleep on. So they built a brand — named for a form of Korean poetry — devoted to engineering sleep products that are both sensorially superior and genuinely sustainable.
That earns SIJO a place as a Seeing Green Solutionist of the Day.

Comfort, Engineered From the Fiber Up
SIJO’s lineup includes sheets, comforters, pillows, mattress pads and loungewear, all designed around performance materials and better sleep.

Across those products, the throughline is material choice.
SIJO works with fibers like eucalyptus, linen, cotton and bamboo — each selected for a specific performance benefit, whether that’s breathability, temperature regulation or durability over time. Many of these materials also come with a lighter environmental footprint, particularly when compared to conventional cotton, requiring less water, land and chemical input.
The sourcing is part of the product.
The Credentials Are Real
SIJO is a certified B Corp, meaning the brand has been independently evaluated across social and environmental performance.
Beyond that, its products are backed by certifications that speak to the things that matter most in this category, including organic materials, the absence of harmful substances, suitability for people with allergies and responsible sourcing practices such as forest stewardship.
In a space where sustainability claims can be easy to make and hard to verify, that level of third-party validation helps separate signal from noise.
A Second Life for Bedding

One of the more distinctive elements of SIJO’s approach is Refresh by SIJO, a program that gives pre-loved bedding a second life. Items are inspected, sanitized and returned to circulation, extending the lifespan of materials that would otherwise be discarded.
It’s a built-in recommerce layer and a practical example of how small decisions can add up over time.
The One Percent That Goes Further
With every purchase, 1% goes to a nonprofit of the customer’s choosing, including organizations like One Tree Planted, World Central Kitchen and the Center for Women and Enterprise. It’s a simple mechanism, but one that reflects how the brand approaches impact: as something embedded in everyday choices rather than a single defining gesture.
Bedding is something we use every night, but rarely think about. The materials, sourcing and lifespan of these products can have a meaningful impact over time, both for personal comfort and for the planet.
SIJO is a reminder that even the most routine parts of daily life can be rethought — and improved — through better materials, better design and a longer-term view of impact.
