Orthopedic Memory Foam Seat Cushion - Coccyx Cut-Out Wedge for Tailbone & Lower Back Support, Office Chair, Car & Travel

Eight hours on an office chair, a long day behind the wheel or a bus journey to another city all end the same way: an ache at the base of the spine and a lot of shifting around to get comfortable. A flat, hard seat pushes your weight straight onto the tailbone. This cushion changes how that weight is carried.

It is made of high-density memory foam shaped like a U, with a cut-out at the back. When you sit, the tailbone sits over the gap instead of pressing into the seat, and your weight spreads across the thighs and hips. The front is contoured to follow the legs, and the cushion slopes slightly so it encourages a more upright posture rather than slouching.

Memory foam responds to body heat. On a cold winter morning it will feel firm at first, then soften and shape itself to you within a few minutes of sitting. The underside has a non-slip base that keeps it from sliding forward on an office chair, a car seat or a wheelchair, and the cushion is light enough to carry between the office, the car and home.

The soft, breathable cover comes off for washing. Wash only the cover and let it dry fully before putting it back - never wash or soak the foam itself.

Two practical notes. In a car it raises you slightly, so check that you still have head clearance and a comfortable reach to the pedals before driving with it on the driver's seat. And it is a comfort cushion, not a medical treatment: if you have persistent back or tailbone pain, see a doctor.
