Headrest Tablet Mount — Adjustable Back-Seat Holder

Clamps onto the back of a front headrest and turns the rear seat into a cinema. Keeps a tablet at eye level for whoever's back there, so the long drive stops being a negotiation.

Specs at a glance:

• Holds phones and tablets from 5" to 12.9" — the cradle opens from 13.5cm to 26cm
• Height adjusts 10cm to 27cm, and the arm folds flat against the seat when you're not using it
• 360° rotation with 180° vertical tilt, so it works in portrait or landscape
• Cut-out at the base leaves the charging port clear — it can charge while mounted
• Padded contact points on the clamp and cradle to protect the seat and the screen bezel

Worth knowing — check this before you buy: it mounts by clamping around the two metal posts of your headrest, and it fits a post spacing of 4.7" to 5.9" (roughly 120-150mm). That covers most cars, but it's a genuine limit rather than a "universal fit" — worth measuring the gap between your headrest posts first. It also won't work on seats with fixed, non-removable headrests that have no exposed posts.
