Booster seat that can take a H Harness

Hello all,

My daughter is turning four in march and will need to move into a booster seat (not to mention that we have twins arriving in June and her current seat will need to be used!). The middle seat on my car has a lap belt only. So when she grows out of the inbuilt harness in her new booster seat, I need to put a H Harness on her.

Does anyone have recommendations about what the best H Harness compatible booster seat would be?

Thanks in advance!

We have a safe and sound Hi liner for DS1. He has a H harness. It is a safe seat and he says he is comfortable in it and loves it.

Would recommend it to everyone.

We love the Hi-Liner, but we also don't use the H.
My mum does and says it works well for her girls but we dont use it due to the research re unnecessary unless lap sash only, obviously that doesn't apply to you!!
