About this product

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.

What it does

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.

1

Suspends the coccyx

The horseshoe-shaped cut-out helps eliminate direct pressure on the tailbone while sitting.

2

Encourages upright posture

The wedge shape creates a gentle anterior pelvic tilt that supports the natural curve of the lower back.

3

Distributes sitting weight

Weight is distributed across the sit bones and thighs rather than concentrated at the tailbone.

4

Reduces slumping

The forward pelvic position reduces the tendency to slump into a rounded lower-back posture.

5

Portable support

Lightweight construction and a carry handle make it practical for the office, car, home, and travel.

6

Soft plush cover

A removable velvet-style cover adds comfort and can be machine washed when needed.

How it helps you

Helpful for tailbone discomfort and seated posture

  1. 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.
  2. Post-childbirth recovery: A coccyx cushion can help reduce sitting discomfort during postpartum healing when the tailbone has been bruised or irritated.
  3. Lower back and lumbar support: The wedge shape encourages lumbar lordosis, which can reduce strain during long periods of sitting.
  4. Post-fall or trauma recovery: The cushion helps manage seated pressure while the area recovers from bruising, irritation, or injury.
  5. 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?

Tailbone clearance: The rear cut-out suspends the coccyx so it is not compressed against the chair.
Postural benefit: The wedge profile supports pelvic positioning and lower-back alignment, unlike many flat donut cushions.
Daily usability: The compact shape works on office chairs, car seats, dining chairs, and other firm surfaces.
Transferable support: The carry handle makes it easier to use consistently across different seated environments.
How to use

Position the cut-out at the rear of the chair

  1. 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.
  2. Sit fully back so your tailbone sits within the cut-out space, suspended above the seat surface.
  3. Your weight should rest on your sit bones and the backs of your thighs, not directly on the tailbone.
  4. Your hips should feel slightly tilted forward, with a gentle curve in your lower back.
  5. Use consistently across seated surfaces throughout the day, including the car and at home, for best results.
  6. 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.

FAQs

Frequently asked questions

It is suitable for people experiencing coccyx or tailbone discomfort, postpartum sitting discomfort, lower back discomfort related to prolonged sitting, or those looking to improve seated posture. If you are unsure whether it is appropriate for your condition, speak with one of our team.

Yes. The cushion can work as a passive support tool between appointments by reducing aggravation to the coccyx and helping reinforce seated posture. It does not replace treatment.

For many people with coccydynia, a U-shaped wedge cushion is preferred because it provides tailbone clearance while also supporting pelvic and lumbar alignment. A traditional donut cushion does not provide the same wedge-based postural support.

The cushion is a management and comfort tool, not a cure. It relieves pressure during sitting, which may reduce ongoing irritation, but it does not address the underlying cause of the pain.

Yes. It works on many car seats and can be helpful for people who commute or drive long distances. The carry handle makes it easier to transfer between the office, car, and home.

The thicker end goes at the back, with the horseshoe cut-out facing the rear of the seat. Your tailbone should sit in free space within that cut-out while your weight rests on your sit bones and thighs.

The velvet cover is removable and machine washable. The foam core should not be submerged in water. Spot clean the foam if needed and allow it to air dry fully before replacing the cover.
