Car phone and tablet headrest holder HOCO CA121 for 4.7"–12.9" devices, adjustable mount for rear-seat viewing

Hoco CA121 is a car headrest phone and tablet holder designed to keep passengers entertained on long journeys. It supports devices with screen diagonals from 4.7" to 12.9" and secures to headrests that have two posts spaced 108–245 mm apart.

Advantages

The holder offers 360-degree adjustment for easy positioning of phones or tablets at a comfortable viewing angle. Soft silicone pads cover the jaws and the front of the handle to stabilise the device and protect it from scratches. Its clamp-style mounting is easy to install and the unit supports both vertical and horizontal device orientation.

Suitable for

• Watching videos and movies in the back seat
• Hands-free video calls or online lessons on a tablet or phone
• Keeping children entertained on long car trips
• Using a tablet for maps or apps by rear passengers

When it may not be suitable

This holder requires a car headrest with two posts and a spacing between 108 and 245 mm; it cannot be used with integrated or non-adjustable headrests that lack accessible posts. Very heavy oversized tablets near the upper limit of the supported diagonal may reduce stability depending on vehicle movement.
