high back boosters with straight sides?

[naturalbaby]

We have 3 car seats in a row, 2 of them are high back boosters. I'm looking at replacing our car and possibly the car seats. One of the high back boosters has minimal side protection but fits well beside the other car seats, the other has really good side protection but has such big 'wings' at the side that the car seats push against eachother and it's like a puzzle getting them all to fit in the car!
so I'm looking for a high back booster a bit like this rather than this but ideally less than £100.

I use the Britax Adventure because it doesn't have the big 'shoulders' that other seats have.

Hello, I'm looking at HBB too and just came across this! Seems like a very good price. Hope that helps.

And it's on Amazon at at a few other baby sites for the same price. I feel a purchase coming on!

I love the look of the Concord and have a few of their other products...
One of the school mums has 3 of them i a row but I suspect they may be the £250 seats rather than the £80 seats!

We have the Britax adventure too and its great because its so narrow but had really good side impact protection.

We got ours on sale at Argos for £25.

The Britax adventure does look good. We have the Romer with bigger wings so wasn't sure how they compared for safety since finding out our cheap Graco one was on the Which worst buy for it's side protection.
