McKesson Coccyx Seat Cushion β 18x14x3", Ergonomic, Blue Cover
McKesson Compressed Coccyx Seat Cushion (18" x 14" x 3")
Anatomical Rear Cut-Out for Direct Tailbone Offloading, Forward Ergonomic Posture Wedge Tilt, and High-Resiliency Foam in a Washable Navy Blue Cover
The McKesson Compressed Coccyx Seat Cushion delivers a target-specific pressure relief and postural support solution meticulously engineered to eliminate tailbone discomfort during extended sitting. Prolonged sitting on unsupportive office chairs, car seats, or wheelchair frames transfers body weight directly onto the base of the spine, leading to coccyx soreness, lower back fatigue, and spinal compression. This high-performance posture cushion resolves those everyday challenges, incorporating a strategic rear cut-out that suspends the tailbone above the seating surface to prevent direct pressure and promote lasting seating comfort.
Constructed from high-resiliency, durable foam, the 18" W x 14" L x 3" H cushion features an ergonomic forward tilt that tilts the pelvis gently forward, encouraging the natural S-curve of the spine and preventing slouching. It arrives in space-saving compressed packaging and expands quickly to its full 3-inch thickness once opened. Outfitted with a removable, machine-washable navy blue cloth cover for simple hygienic maintenance, this FSA/HSA eligible cushion is 100% latex-free, making it a safe and versatile choice for home desks, vehicle seats, and daily mobility setups.
Key Features & Benefits

- High-Resiliency Foam Core: Built with durable foam that maintains its supportive shape and cushioning bounce without flattening out over time.
- Compact Compressed Shipping: Shipped in vacuum-compressed packaging for easy transit, expanding rapidly to a full 3-inch thick support surface upon opening.
- Removable Machine-Washable Cover: Includes a soft navy blue cloth cover that unzips easily for quick cleaning and long-term hygiene.

Equipment Specialist Insight: Positioning a coccyx wedge cushion properly is key to achieving optimal pressure relief. Always place the cushion on the seat with the U-shaped cut-out facing toward the back of the chair. When seated, your tailbone should hover directly over the empty cut-out area rather than resting on the foam. The higher back portion gently tilts your hips forward, opening up your hips and reducing slumping while working at a desk or driving.

Frequently Asked Questions
How long does it take for the compressed cushion to fully expand after opening?
Once removed from its compact packaging, the cushion will begin expanding immediately and typically reaches its full 3-inch height and firm density within a few minutes. In some cases, allowing up to 24 hours ensures the foam fully expands to its ultimate shape.
Which way should the cut-out face when placing the cushion on a seat?
The U-shaped cut-out section must face the back of the chair or seat. This position aligns the cutout directly underneath your tailbone (coccyx), allowing the spine base to float pressure-free while the surrounding foam supports your buttocks and thighs.
How should I wash the navy blue cloth cover?
Unzip and remove the cloth cover, then machine wash it in cool or warm water with a mild detergent on a gentle cycle. Air dry or tumble dry on low heat. Do not submerge or machine wash the inner foam core; spot clean the foam with a damp cloth if necessary and allow it to dry completely before reinserting it into the cover.
