Feather-Light, Soft Fabrics

Zenbivy’s Ultralight Bed features premium 10D Pertex® Quantum fabrics, a feather-light, soft-to-the-touch fabric that feels like cloth—never sticky or plasticky—thanks to its unique design that doesn’t require calendering on both sides like other ultralight fabrics.

Fast Footbox™

Unlike sewn footboxes that restrict your movement and do not vent, Zenbivy’s patent-pending Fast Footbox™ uses a single clip that allows it to expand for more space or narrow for more warmth.

Fits Most Mattresses

Zenbivy sheets are designed to fit most standard size mattresses on the market, including rectangular and tapered styles.
