Which car seat is best to move between cars regularly?

[JohnLewisAddict]

DS is almost out of his rear facing maxi cosi seat so I've been looking at FF ones. I drop him off at nursery in the morning and DP picks him up so I need one that can move easily from one car to the next. Unfortunately having 2 car seats isn't really that feasible due to cost and I'd rather pay more for one really good one that half the budget to get two. We can leave the car seat at nursery in a shed so storage isn't really an issue. Just want one that is a) safe and b) easy to remove and refit when we drop DS at nursery. Thanks!

If I have done this properly on my phone, this should be a link to a blog post 'replying' to Which?'s take on rear facing seats for toddlers and older children www.rearfacingtoddlers.com/blog

My DD2 is in a Which? 'Don't Buy' seat - the Britax Multi Tech II ERF seat (Which? have reviewed it as the Volvo convertible). Again, they have marked it down for being hard to fit - which it is not! It takes more time to fit, but is definitely not hard to do. I don't mind spending 3 minutes fitting my DD's car seat if it means she's as safe as she possibly can be.
