LO is 15 months and the ILs will be watching her 1x a week starting in September. We're getting her a secondary booster seat for their house.

But I'm wondering if I'm better off buying a "booster" seat that's multi purpose like this:

rather than say a FP Healthy Care Deluxe.

ETA: They're both portable but I like how the regalo folds up even smaller so we can use that when we travel to my family.

Thoughts?
