Our Comfort Car Headset Pillow is scientifically ergonomically designed and supports and protects your head and neck comfortably. Sleep safely without neck and shoulder pain with the car neck support and headrest! Both side headrest pillows can be rotated 180° to adjust the height, with the movable distance of 2 cushions between about 15 and 27 cm, so that both adults and children of different sizes can find a comfortable position. When not in use, simply lift the pillows up to save space. Our car seat pillow is made of memory foam, ABS and leather. The removable PU leather side cushions with thickened, breathable and warm memory foam prevent head bumps caused by the movement of the vehicle while driving. No tools are required for installation, which is easy. The headrest of the car has a double safety buckle, which significantly increases stability. Compatible with most car seats with metal headrest bars and an inner width between 7 cm and 21 cm. Please make sure your car seat has a metal bar that can be moved up and down before purchasing. This product must be used together with metal rods. We always maintain high quality standards for our car headrests and provide professional after-sales support. If you have any questions about the car headrest or are not sure whether your car fits, you can send the email via Amazon and we will offer you a satisfactory solution.
