Recommended for all car journeys, this very ingenious accessory repositions the seat belt for pregnant women so it does not press on the tummy. It is more comfortable for mums-to-be & avoids extreme pressure being exerted on the unborn baby from the seat belt as a result of an impact or sudden braking. Fit the cushion onto the car seat & attach the strap to the back: then when you get into the car, simply insert the tummy belt into the seat belt guide & fasten with the press-studs. Does not interfere with the function of the seat belt. 1 year guarantee.
