Ideal for: office chairs, home offices, study spaces, and everyday seating.

Designed around the way you actually sit
-
1
Tailbone
The U-shaped cut-out lifts pressure off your tailbone so it never touches a hard surface.
-
2
Hips & sit bones
Contoured memory foam cradles both sides evenly so weight doesn't pool on one hip.
-
3
Lower back
An even seated base keeps your pelvis level, which takes strain off your lower back.
-
4
Thighs
The tapered front edge avoids pressing into the backs of your thighs, so circulation stays easy.

How it holds up
What tailbone pain actually costs you
A cushion is a small line item next to what most people spend chasing relief.
Three steps to a better seat
01
Place
Set the cushion on your chair with the notch toward the back edge.
02
Settle in
Sit back so your tailbone rests in the open notch, not on the foam.
03
Sit through it
Work through your day as usual — the foam adjusts to you, not the other way around.
