Adjustable Ergonomic Memory Foam Coccyx Seat Cushion – Tailbone Relief

Custom Fit. True Tailbone Relief. All-Day Comfort.

The Healtence Adjustable Ergonomic Memory Foam Coccyx Seat Cushion delivers personalized orthopedic pressure relief for your tailbone, hips, and lower back. Designed with an adjustable-width buckle mechanism and an ultra-supportive 5.5-inch contour profile, it adapts to your unique body shape and seating environment to keep you sitting comfortably for hours.

Tailored Ergonomic Support for Every Body Type Standard flat cushions compress under body weight and fail to cradle the pelvis correctly. This seat cushion features an adjustable center strap connecting two contoured support wings, allowing you to widen or narrow the cushion to match your exact hip width, keeping your spine aligned and floating your coccyx above hard surfaces.

Key Benefits & Features:

• Customizable Width Adjustment: Built-in adjustable bottom strap allows you to expand or contract the spacing between both support lobes for a custom-tailored anatomical fit.

• Elevated 5.5-Inch Orthopedic Profile: Generous 14 cm contour depth provides substantial pressure redistribution, absorbing body weight and preventing the cushion from bottoming out.

• Dual Air-Flow Ventilation Ports: Engineered with two central ventilation hollows that facilitate continuous airflow, dissipating heat and keeping you cool during long work or driving sessions.

• Targeted Coccyx & Sciatica Relief: Deep anatomical rear cutout ensures zero direct contact between your tailbone and the chair surface, easing pressure along the sciatic nerve.

• Durable Mesh Cover with Premium Zipper: Breathable dual-texture outer cover zips off smoothly for quick machine washing, backed by a non-slip textured base to prevent shifting.

Frequently Asked Questions (FAQs)

How does the width adjustment work? The cushion is divided into two ergonomic halves connected by an adjustable strap on the underside. By tightening or loosening the buckle, you can adjust the distance between both halves to match your exact hip measurement and seating preference.

Will this cushion fit my office chair or car seat? Yes. At 18.9" wide by 15.4" deep (48 x 39 cm), it fits standard office chairs, desk chairs, and car bucket seats. The adjustable strap also allows you to narrow the profile slightly for more compact automotive seats.

How does the 14 cm (5.5") thickness help with pain? The generous height provides ample clearance to keep your coccyx suspended completely off hard seat surfaces. The high-density memory foam contours to your hips and thighs without compressing flat, maintaining proper pelvic tilt and lumbar posture.

How do I clean the cushion cover? Unzip the heavy-duty hidden zipper along the back and remove the outer mesh cover. Machine wash on a gentle, cold water cycle and hang dry. Spot clean the memory foam core with a damp cloth if needed.
