The Babylove Ezy Fit II Booster Seat is an affordable height-adjustable booster seat. With side wings for side impact protection safety, it scored 4.6 stars on the CREP safety protection rating. Feature wise, what you get by spending a few extra bucks over a basic booster seat is a 5-position height adjustable headrest, arm rests and a more comfy cushion.
However, the upper marker is very low at 48cm, which may mean your child outgrows the seat well before 8 years. If this happens, you may need to use a second booster seat before they can fit a normal car seat. If this is just a second seat, then that might be ok, but if it’s your main seat, it might be a deal breaker.
$129 is neither cheap nor expensive for booster seats, but might be a lot if it’s only used occasionally.
