full booster seats - do they all fit all cars?

[mckenzie]

or are they car specific like the second stage seats etc?

TIA

High back boosters should fit most cars. Some have a slight recline facililty, so if your car has a sloped seat back it might be worth going for one that does

thanks differentID. i seem to remember DS looking very uncomfortable on the odd occasion he feel asleep in his so I will definitely look into a reclining one for DD.
