Product Material: Polyester Fiber + Lycra Size: 46 * 41 * 30 cm Operating Temperature: -25 Degrees Celsius to 70 Degrees Celsius Color: Black, Gray, Blue Quantity: 1 Piece Package Content: 1 Piece Inflatable Cushion 1. Long-Lasting Comfort: Specially designed to provide extra support for your hips and back, with 42 plump 3D air cells covered with breathable Lycra fabric. This pillow provides excellent lumbar support that can help distribute the pressure from sitting up to 30%, reducing pain and discomfort. 2. Ergonomic Design: Compared to foam support cushions, the inflatable seat cushion is durable and adjustable. It is easy to achieve the desired level of inflation or even fully inflate. 3. Fresh and Dry: The design maximizes air circulation. When one cell is compressed, the air flows to other cells around it. This reduces heat transfer and the uncomfortable feeling of prolonged sitting, while supporting your posture and helping prevent discomfort from extended sitting. 4. Class A Anti-Slip Effect + Highly Elastic Lycra: This pressure-reducing seat cushion is made of highly elastic Lycra, which can come into direct contact with the skin. The fabric is smooth and comfortable, with good crease resistance, allowing the hips to breathe freely. The bottom of the cushion features more than 40,000 anti-slip particles, providing strong anti-slip performance. 5. Portable Inflatable Air Cushion: Lightweight and easy to carry, suitable for use on car seats, wheelchairs, office chairs, computer chairs, home chairs, or seats on public transportation such as airplanes, subways, buses, and trains.
