Sitting Box



The Sitting Box is an extremely versatile reformer accessory that is used frequently during classes in the Flexia Online Studio. 

Flexia’s Sitting Box design is special, as there are hand cutouts beneath and an open box design to facilitate easy transport. Simply grab the Sitting Box from virtually any angle to pivot, move, or carry.  

Additionally, Flexia’s Sitting Box fits the exact width of the Flexia Reformer, so no corners will protrude off of the reformer, as is the case with many other sitting box designs.

Flexia's Founder and CEO, Kaleen, on our Sitting Box design, “The sitting box is a portable accessory. You’re constantly moving it throughout a session, so searching for a specific handhold to move it can be limiting.  I wanted ours to be super easy to grab from any angle–and also look beautiful in your home as an accessory.”
