I'm about to buy a Dualfix as a second ERF seat (for my parents' cars - they frequently babysit my 18mo). I just wanted to double check that it's definitely large enough for a 4yo? My DM's car is too compact for a BeSafe, and I think a BeSafe would be too fiddly to install and then uninstall multiple times a week. I'm looking for a little reassurance that if I buy the Dualfix it will definitely take my DD through until she's tall/heavy enough for a Group 2 seat? Has anyone actually put a 4yo in a Dualfix?
Thanks in advance for any comments!
