Police cars use these laptop tables a lot, so we know they are solid and stable. There are two main types of car laptop mounts, ones that sit in the passenger footwell and ones you can hook over the back seat of the car.
One of our favorite products is these tables that hook over the steering wheel. Of course, these are better in larger cars as space can be rather restrictive, so it could be a good idea to check the full product dimensions before ordering. However, they also work well in the back of the car.
