Narrow car seats

[Ellie4]

I am interested in finding out which car seats are narrow and I thought people here may have experience in this. I am looking for a high back booster seat.

So far the Mothercare Sola and Advance SP look quite narrow and look like they would sit next to each other quite well if we needed to buy another in the future. It does not need to be with a 5 point harness though.
I don't live in the UK so I don't have the option of taking the car to Halfords or Mothercare and seeing which combination will fit.

Many Thanks

The Nania seats are very narrow. They are the any ones that fitted in my friends car. She needed to get three across the back. They are quite good but unless you need to get three across the back now I would get a better seat like a britax one and get different ones if and when you need they. My dd aged nine would nee the back off soon although it does look like from the picture that they have changed them. Her britax one will take her up to 150cm tall. Narrow ones tend to be very cheap

Thanks castle. I will need to get three across the back in Feb. Baby will be in 0+ and base, DS2 is in a britax stage 1 and I'm looking to change DS1's britax stage 1-3 which is very wide. Will need though to get another new seat when baby moves into stage 1 seat so was looking for seats that fit closely together but still leave enough room to do up the seatbelt iykwim.

I second the nania seats. We've got one in dh's car as second car seat. The width wasn't the issue - for me it was cost, for dh it was that it came in lots of colours and therefore fitted in with his upholstery . It's good though. More padded than lots of the graco ones at twice the price. I have a Britax trio in my car and actually prefer the nania. Even though it was 4x the price!

We had this battle when we had DS and needed to fit 3 car seat across the back seat. I went to a shop and we tried all sorts of seats and combinations. We ended up having to get a Maxi-Cosi Robi high-back booster instead of the Britax high back booster due to the difference of about 2cm.

We have DS (9 months) in the Maxi-Cosi Cabriofix with Isofix base on the passenger side. DD1 in the Maxi-Cosi Robi in the centre. Hers anchors into a plug next the iso-fix base and we had to wedge facecloths around the plug to ensure the plug remained upright and easy to get the strap into - it is a bit fiddley at first but fine once you are use to it. DD2 (almost 3) is in a Britax First Class car seat behind the driver.

I think when DS comes out of the Cabriofix he will go into the Britax First Class and I will get another Maxi-Cosi Robi for DD2.
