This base makes it quick and easy to secure your baby in the car seat into your car. This is not an essential piece of baby kit as you can secure the car seat with seatbelts but this takes time and can be fiddly especially when some seatbelts seem too short to reach around the car seat easily. This product takes all the stress out of transferring your baby in and out the car and also means you can attach and detach your baby more smoothly without waking them if asleep. The car seat slots into the base easily and a coloured indicator turns from red to green when the car seat is fixed securely (on some occasions when the indicator is green a little bit of red is still visible but still means the car seat is secured). You pull a grey area outwards away from the seat back to release the car seat. It is not difficult to attach the base to your car's isofix points. Expensive but well worth the money as will be used often, saves you time and hassle and gives you peace of mind.
