We're providing peace of mind — for bedtime and beyond.

Anastasia A.

A pregnant woman sits in a cozy chair by a window, resting her hand on her belly and looking outside. Beside her is a light gray and wood baby bassinet. The scene appears calm and peaceful.

“We love our bassinet for its safe design and breathability! NO other sleep products give us the peace of mind that Newton does. ”

Melissa B.

A baby wearing a white onesie sleeps on a quilted, light gray mattress next to a bed with cream-colored bedding. Sunlight gently illuminates the baby and part of the bedding.

“The BEST. I sleep better, baby sleeps better. The height adjusts which is so helpful especially post C-section. Highly recommend!”

Jessica M.

A woman sits on a bed holding a newborn baby while a toddler sits nearby. A bassinet is next to the bed, and the room is decorated with neutral tones and soft lighting.

“So beautiful and fits so nicely next to my bedside. Such a relief to not be concerned when your newborn wiggles onto their side.”

Alyssa S.

A baby sleeps peacefully on a gray, cloud-patterned mattress, wearing a gray onesie with white sun and cloud designs. The baby is lying on their back with one arm raised and eyes closed.

“Love this bassinet! Incredibly sturdy and I love the drop side so I can easily see baby while in bed. Very happy and highly recommend.”

Ana A.

A smiling woman in a white robe stands beside a bed and a gray bassinet with a stuffed bunny inside, in a cozy, well-lit bedroom with neutral decor.

“This is the only bassinet we are comfortable with allowing our daughter to sleep in due to its breathability.”
