Our Story

We created Nyssa

after being shocked, frustrated, and let down by the few resources and products available to support us during our Fourth Trimester recoveries. New parenthood can be intense and identity shattering. We want to have an honest, open dialogue about what really goes down while also providing birthing parents with empathetically designed products that make care and comfort a priority.

The Community Speaks

I'm buying [Fourthwear™ Underwear] for every pregnant person in my life.

Ann Friedman, Journalist & Podcaster

I can confirm that postpartum life is 90% better when you don’t rip to your butthole. Baby boy: 1 point. Luna: 0.

Chrissy Teigen, Model & Author

Motherhood transforms us. It is not that we become different people or that we lose ourselves. It is that we discover feelings, impulses, thoughts, and wishes within ourselves that we likely never would have encountered had we not become mothers.

Dr. Molly Millwood, Clinical Psychologist

Fourthwear is a critical part of my post c-section recovery. I love the high waist that gently supports my body as it adjusts to being suddenly un-pregnant.

Melissa, Chicago

As women and mothers, we need to know that we don't have to sacrifice our bodies to have babies. We deserve better care and we need to demand it.

Sara Reardon, Pregnancy/Postpartum Pelvic Health Physical Therapist

I’m going to recommend Fourthwear to all my patients.

Dr. Laura Stock, OB-GYN 

Postpartum recovery is complex. We cannot expect a mother to adequately heal unless her emotional, social, nutritional, environmental, and physical needs are met.

Taylor Kulik, Postpartum Wellness Consultant

Families spend thousands on baby clothes, newborn photos, and a bedroom that the baby doesn’t really sleep in for the first six months (and shouldn’t for safety reasons). The baby doesn’t care how cute their room is. What if instead of decorating a nursery, you put that money towards postpartum care?

Kayla Levine, Postpartum Doula

I’m so in love with these. Everyone needs a pair.

April Davis, The Vagina Blog
