A surface that is not your knees
Trays, stands and clamps for a parked car, sorted by what actually stays put.

Steering-wheel trays: fine, when parked
The steering-wheel tray is the default car desk, for good reason. It hooks over the wheel, gives you a flat surface at about chest height and folds away at the end of the day. Good ones have a raised lip, a grippy surface and a bracket that grips the rim at two points. Bad ones are a slab of plastic that slides towards your stomach at the first lean.
One rule, no wiggle room: it is for a parked car, handbrake on, ignition off or at least in park. A tray on a wheel is not a driving accessory and the laptop is not a satnav. Handheld device use while driving is illegal in the UK, and a lap-high screen is worse than a phone.
What to look for: a surface wide enough that a 15-inch laptop does not overhang, a mount that fits your wheel diameter, and a stop on the bottom edge so nothing creeps. Left-handed? Check the mouse area sits where you need it.

Dash and passenger-seat stands
A stand on the dashboard raises the screen to eye level, which your neck will love. Dashboards are also curved, sun-baked and home to airbag covers. Never place anything on or in front of an airbag panel; many cars mark them with SRS or AIRBAG lettering, and your owner's manual shows the rest.
For a long stint the passenger seat is a better base. A weighted fold-flat stand, or a board resting across the seat and centre console, gives a stable surface. Add a compact folding Bluetooth keyboard and a small mouse so your wrists are not hovering mid-air.
If you drive a van daily, vehicle mount makers such as RAM Mounts and Havis build bolt-in laptop pedestals. They cost more than a tray because they are made for daily use and for being fitted properly, not balanced on a hope.

// desk 03 · cables
Cables are the real clutter
A cable sliding off the dash into your lap is both messy and hazardous. Use adhesive clips along the dash edge, a short coiled lead for the phone and a right-angle USB-C connector where space is tight. Keep cables clear of the pedals, gear lever, handbrake and airbag zones.
A pack of 20 cm hook-and-loop ties costs less than lunch and does more than most gadgets. Label your chargers if you share the car. A tidy loom makes for a tidier head, and a much quicker pack-down when the next job calls.

Desk kit, ranked
- 01
Steering-wheel tray with a lip BUY
Best all-rounder. Cheap, quick to set up, stores flat behind the seat.
- 02
Weighted passenger-seat stand BUY
Steadier than a tray for long sessions. Needs an empty passenger seat, which is the point.
- 03
Folding Bluetooth keyboard BUY
Lets the laptop sit high while your wrists stay low. Pocket-sized.
- 04
Adhesive cable clips and ties BUY
The least glamorous purchase here and one of the most useful.

Anti-slip dash mats as laptop bases SKIP
They creep in the heat and tilt when you type. Fine for sunglasses, hopeless for a laptop.
