Designed around

Memory foam build

The core uses responsive foam to contour to the body. It is intended for users who sit for extended hours.

Multi-use compatibility

These models fit office chairs, car seats, and wheelchairs. The sizing remains consistent across different environments.

Tailbone focus

The titles emphasize relief for tailbone pain. The shape reduces direct contact between the spine and the seat.

Stability features

Each unit includes a non-slip layer. This prevents the cushion from sliding during use in a vehicle or desk chair.
