I can not rate this car seat high enough. We bought the top of the range for our first and it was so amazing we bought it again for our second. It is worth every cent ! Babies and toddlers are always comfortable. It is so easily adjusted for height and inserts and rear or forward facing. Babies have never been hot or sweaty in it.

Love the breathable material. The old seat we had would leave my son sweaty. Much wider for comfort also. The adjustable headrest with the SICT protection is an added bonus to use like a pillow when bub sleeps. The isofix needs to be clearly stated that it is actually inside the seat. Took me ages to figure that out. All in all it’s a great seat will worth the price.

I Incorrectly bought the wrong car seat for my 2year old grandson, but the lady who fitted the seat gave me advice on what I should buy. I thanked her for the advice for an appropriate car seat. only took twenty minutes to fit. The staff and the nice lady who fitted my car seat were friendly and efficient. highly recommend baby bunting Campbelltown store

Fabric looks higher end than most other car seats. I also love the plastic hooks either side while hold the buckles back when putting baby in
Very comfortable for baby, with beautiful material. Fits Corolla but bought for a rav 4 with a bit more room.
Great seat for our second car. Larger shell compared to others seats - mainly in depth over width. We also have the Maxi Cosi Vita Pro and it's a good 5-8cm less depth when in rearward facing mode. Adjustments are way easier B-First, although installation took twice as long due to the under seat location of the ISOFIX tethers. Aside from bulky size, only negative so far if the excess top tether storage bag feels cheap and simply hangs and hits passenger door. Vita has a nice storage location in that respect. The Vita probably is more cosy for a newborn, with the B-First well suited to keeping our little one comfortable a little longer. First world problem - but B-First is a really nice looking seat. Feels solid.
Secure car seat thats easy to install and easy to use.
Our daughter loves her car seat and we have peace of mind that it keeps her very safe
Leaving a review because I know first hand how overwhelming buying a car seat for your baby can be. The seat we had previous to this was rigid, hard to tighten the straps, hard to get my son both in and out of. I avoided going out at all costs, so there was really no use even owning it. This chair on the other hand is so easy to use, baby looks comfortable and sits at a really nice angle. (Previous chair his head hung really “forward” which always made me nervous). Soft material for bub too. Really happy with this seat - works well for our family.
