The best purchase for my newborn!!

I was unsure if I should get a capsule or not and so happy I did! I could transfer my baby in and out of the car while she slept saving me to much time and stress! The Britax safe n sound was so easy to install! I installed it so fast in other peoples cars if I was ever swapping cars and no hassle at all! My baby is now 8 months and only just growing out of it! 100% recommend to all parents! Show details ·  1

Poor head support

My newborn’s head flops around dangerously. Its installed correctly but we now have to reinstall it with towels to try get the seat to tilt back further. I’ve never had this issue with other branded capsules so very disappointed.

The buckles dig in to his little legs and the sun canopy is useless.

At first it was alright but after a couple of uses, the buckles got stiff and were a pain to use. Wouldn't recommend, unless your budget pleads you too. It's a pretty one though, in terms of how it looks and feels, my kid was very comfortable in it when we first got it.

Best ever

This is the first capsule Iv used ever

I'm loving it so easy to used baby sits nicely inside and you can connect to any pram

This is by far the best capsule Iv seen yet used for my baby. This is definitely a great buy and would recommend it to everyone that's looking to buy one. :)

Does the job!

I hired the capsule as I didn't feel the need to buy (in hindsight I should have as I'm pregnant again). My baby is 7 months is 75% height and 98% weight and still fits well with room to grow. The capsule with my 10kg baby is a little heavy now but I don't tend to carry her in it any more unless its to attach to the stroller so she can continue to sleep. I also hired the conversion bar to allow the capsule to fit to my stroller (snap 4). I can flip open the stroller with one hand, fit the converter bar and drop the capsule into the locks in less than 30 seconds -its been brilliant!

Solid but cumbersome and heavy

I bought this capsule in 2013 mainly because of it's compatability with the Mountain Buggy Swift. While I appreciated the convenience of this capsule with my first baby - I always felt it was really heavy and the capsule release latch would sometimes be sticky when removing from the base. It's a sturdy unit. However with my second baby I've found these issues to be even more an issue since the need to carry the capsule with a toddler in tow has proven to be extremely hard work. I also find that the infant insert is almost pointless as its barely a head support and with out it there is little padding for the infants back and bottom. I've since tested other capsules that are much lighter, more slim line and feel more comfortable to carry.

Too Heavy and Hot also Not suited for moulded car seats

Capsule itself is far too heavy and has far too much "unbreathable" padding which caused our baby to constantly overheat and sweat horrifically. Took capsule to plunket nz to get it installed by their trained car seat installer and she advised that the capsule was not ideal as straps weren't even and padding around bubs could cause heatstroke. It also didn't fit our cars seats properly either and needed a towel proped underneath (plunket suggested this was unsafe and to get bubs in her carseat asap) Not britax fault, but would only consider purchasing if your seats were flat and not shaped to fit the body. Would be ok for cooler seasons and for those with good upper arm strength... useless for woment recovering from c sections.

Fantastic for us

Never had a problem. We did do a lot of 'trial runs' before baby was born to get used to getting it in and out and putting the strap through the plastic slots properly which can be tricky but once you are used to it, you can do it blindfolded. We stopped taking the capsule out of the car with baby after a maybe 7 months (before she used the pram seat) but still served as her rearward facing car seat till she was about 15 months old. This I was really happy with as we always wanted her to be rear facing for as long as possible and this capsule definitely allowed us to do that.

So many frustrating things about this product

For starters the base is IMPOSSIBLE to get level in the back seat. The metal buckle behind the capsule that holds the straps together gets caught all the time. There isn't enough space for it to travel through the plastic form and makes it so that one strap is tighter than the other. The canopy ALWAYS pops off and doesn't sit straight. The gap between the largest two heights for the upper straps is too large. My baby is too tall for the lower level but the next one up is way too high. Very poorly designed seat.

Doesn't last long as too heavy

If I had my time again, I wouldn't buy a capsule.

Capsules are so heavy, especially with a growing baby in them. My mum was right!

We stopped pulling ours out of the car at about 8 weeks, so it was a big waste of money. It is just too heavy. You couldn't take it shopping or anything (even from week 1)

Better off buying a baby strap on carrier (like "baby bjorn" or a "baby k'tan") and a 0-4/0-8 years car seat. Would get so much more use out of both of them.

**My baby is now 7 months and have only just realised the capsule doesn't face forward. My average size 7 months old is also, almost too big for it (her legs hang out a lot and the straps are tight)

Charles · Unity Infant Carrier Standard

We are going travelling soon and have the capsule with the built in click and go adapters. What travel strollers (those that can be put in plane cabin storage) are compatible with the britax unity capsule?

That’s ok, I just mean in general travel sized strollers (eg baby jogger tour 2/baby zen yo-yo)?
