I have a 2 seater car. Is it legal to put the baby seat in the front row?
Yes, it is legal, though not recommended. The safest place for children to be sitting is actually in the middle of the backseat, but some of us who have multiple children or, in your case, have a 2 seater car, have no choice but to put a child in the front seat. If you need to put a car seat in the front seat, slide the seat as far back as possible and you might want to turn the airbag off. If you can't turn the airbag off, do not place a rear-facing infant car seat in that spot! Active airbags pose a huge danger to babies positioned in a rear-facing seat. Those seats position their head so close to the dashboard that they're directly in the air bag's line of fire. (Air bags often burst from the dashboard at 200 mph instantly after a crash. This impact can injure or kill children who are seated too close to the air bag)

Is it illegal to strap a mattress on the top of your car?
The problem is securing it properly. When driving at any speed, the mattress will tend to be blown up and off by the wind and that is the sort of thing that attracts a cop's attention. If you do strap it to the roof, make sure that the front end is tied down tight and that it does not obscure the front or side windows.
