Hello!
My oldest child is 3-1/2 and I'll be having my second child in October. We need to find a booster seat for my 3-1/2 year old which will fit in the Volvo S70 side passenger seat (the infant will be in the other side seat).

Can you all recommend any booster seat you've been happy with that fits into a Volvo S70 or equivalent? We will not be getting a minivan or SUV.
Thanks so much!
