66fit Original Coccyx Wedge Cushion
Tailbone pressure relief and postural support for everyday sitting, with a horseshoe-shaped cut-out and wedge profile designed to encourage a more upright seated position.
Designed to reduce direct pressure on the tailbone
The 66fit Original Coccyx Wedge Cushion is a high-density foam seat cushion designed for people experiencing tailbone discomfort, lower back discomfort, or postural issues from prolonged sitting.
Its horseshoe-shaped rear cut-out helps suspend the coccyx above the seat surface, while the wedge profile encourages a gentle forward pelvic tilt. The cushion is covered in soft plush velvet fabric and includes an integrated carry handle for use on office chairs, car seats, dining chairs, and other seated surfaces.
Simple seated support for daily comfort
The cushion combines tailbone clearance with a supportive wedge shape to reduce direct pressure and encourage better seated alignment.
Suspends the coccyx
The horseshoe-shaped cut-out helps eliminate direct pressure on the tailbone while sitting.
Encourages upright posture
The wedge shape creates a gentle anterior pelvic tilt that supports the natural curve of the lower back.
Distributes sitting weight
Weight is distributed across the sit bones and thighs rather than concentrated at the tailbone.
Reduces slumping
The forward pelvic position reduces the tendency to slump into a rounded lower-back posture.
Portable support
Lightweight construction and a carry handle make it practical for the office, car, home, and travel.
Soft plush cover
A removable velvet-style cover adds comfort and can be machine washed when needed.
Helpful for tailbone discomfort and seated posture
- Coccydynia and tailbone pain: U-shaped or wedge cushions are often used as a conservative support strategy because they remove direct load from the coccyx during sitting.
- Post-childbirth recovery: A coccyx cushion can help reduce sitting discomfort during postpartum healing when the tailbone has been bruised or irritated.
- Lower back and lumbar support: The wedge shape encourages lumbar lordosis, which can reduce strain during long periods of sitting.
- Post-fall or trauma recovery: The cushion helps manage seated pressure while the area recovers from bruising, irritation, or injury.
- Postural correction support: The wedge provides a passive cue to sit with the pelvis in a more neutral alignment between chiropractic visits.
Why a wedge cushion instead of a donut cushion?
Position the cut-out at the rear of the chair
- Place the cushion on your seat with the thicker, raised edge at the back and the horseshoe cut-out facing the rear of the chair.
- Sit fully back so your tailbone sits within the cut-out space, suspended above the seat surface.
- Your weight should rest on your sit bones and the backs of your thighs, not directly on the tailbone.
- Your hips should feel slightly tilted forward, with a gentle curve in your lower back.
- Use consistently across seated surfaces throughout the day, including the car and at home, for best results.
- Remove and machine wash the cover as needed. Keep the foam core away from direct moisture.
Important — please read before use
- This cushion is a supportive comfort aid, not a medical device.
- Consult your practitioner before use if you have experienced a recent spinal fracture, are post-operative, or have been advised to avoid positional seating aids.
- If tailbone or lower back pain is severe, worsening, associated with numbness or tingling, or has no clear cause, book an assessment rather than relying on a cushion alone.
- Speak with our team if you are unsure whether this product is appropriate for your specific situation.
