Do budget car seats that aren’t extremely unsafe exist?! I feel like I’ve gone down a black hole of car seats and am no clearer for it.
car seat would be used once a week by Grandma to pick children up from childcare and understandably cannot afford to spend £100+ per seat due to having to buy one for each child and they wouldn’t get much use. Looking at group 1/2/3 as DC are 2 and 4 but 4 year old is 94cm/11kg so not big enough to use the regular seat belt. 2 year old is 82cm/10kg so plenty of growing room before he can go in a group 2
grandmas car doesn’t have isofix so not an option to leave our car seats in the nursery storage area as ours are isofix.
im ready to sack off the search and just go with the inconvenience of public transport but Grandma is quite determined to get a seat.
does such thing exist?
the closest I’ve found is the Joie Elevate / Elevate 2.0 but because it’s so different from the ones we have in our car I’m just not sure how convinced I am
