Seat cushion Kensington Premium Cool-Gel K55807WW

The Kensington Premium Cool-Gel Seat Cushion (K55807WW) combines a cool-gel core with premium honeycomb memory foam to provide ergonomic support and temperature regulation for office, home or car seating. Sized at approximately 368.3 mm wide × 444.5 mm deep × 78.7 mm high, the cushion is designed to promote healthy posture, reduce spinal pressure and limit contact between the tailbone and the seat surface. The removable, machine-washable cover and anti-slip backing make it practical for frequent use and transport.

Advantages

Cooling fabric paired with a cool-gel core is certified to reduce body temperature during prolonged sitting. The ergonomic shape encourages improved circulation and spinal alignment while a u-shaped coccyx cut-out eliminates direct pressure on the tailbone to help relieve sciatica-related discomfort. The premium honeycomb memory foam offers durable, patent-pending structural support, and independent testing confirms the cushion maintains thickness, support and seam integrity beyond 80,000 uses. A machine-washable cover retains colour after washing, an anti-slip silicone backing prevents sliding, and an integrated carrying strap simplifies transport.

Suitable for

• Office chairs used for long work sessions
• Car seats for commuting or long drives
• Home seating where additional ergonomic support is needed
• People seeking reduced tailbone pressure or sciatica relief

How to use

Place the Kensington Premium Cool-Gel Seat Cushion on a flat seat surface with the u-shaped coccyx cut-out positioned at the back to align with your tailbone. Sit centrally on the cushion so weight is distributed across the honeycomb memory foam and cool-gel core. For car use, secure the cushion with the anti-slip backing against the seat; for office chairs, ensure the cushion sits flush against the chair base. Remove the cover for washing according to the care instructions printed on the label.

Usage recommendations

Use the cushion on a stable, flat seat for best ergonomic effect. Allow the cushion to return to shape after extended compression and follow the manufacturer’s washing instructions to preserve cooling fabric and colour retention.
