Fast Footbox™

Zenbivy's patent-pending Fast Footbox™ uses a single clip that allows it to expand for more space or narrow for more warmth.

Our Solution to the Problem

  • Motion graphic of person kicking their legs around in a quilt with a narrow footbox to demonstrate how restricting it is

    The Problem

    Other quilts with sewn fixed footboxes simply aren't versatile. Sure, they're warm, but they are also narrow, constricting, and they don't vent.

  • Motion graphic of person kicking their legs around in a zenbivy quilt with a wide footbox to demonstrate how versatile it is

    Our Solution

    Our patent-pending semi-fixed Fast Footbox™ design offers both the warmth of a "mummy" footbox and the width of an open quilt, all with just ONE simple clip!

Why It’s Better

  • Woman spreading open the zenbivy Fast Footbox to show how wide it can be

    Extra Space

    Unclipping the footbox allows the quilt to quickly expand for more space, so you can sleep in more sleep positions than you could a narrow footbox.

    Easier Venting

    On warmer nights when you may need a cooling draft, just kick your legs out to quickly vent the quilt.
