Britax Safe-n-Sound Compaq AHR Questions & Answers

I'm just replying again as the official reply here doesn't answer the question at all. Please specify exact technical differences as both seats say they are suitable rear faced for longer. Exact height markers (all three) for both seats and exact dimensions including depth in rear facing position, plus any differences in fabric, would be more helpful. Thanks in advance.

You only need to take slack out of the seatbelt and top tether. Don't shake the car seat. If the movement still concerns you, take it to an accredited car seat installer who can show yo how to install a gated buckle to hold the seatbelt tight.

The dimensions are the same. The MKII just doesn't have the internal headrest, whereas the AHR does.

Yes, you have purchased the older model by the sounds of it. Look for models with three height markers on the cover. The Britax Slimm-line AHR, Infasecure Quattro, and some new Compaq models should have three height markers to allow for longer rear facing to an average 2-3 years.

In a roundabout way you have kind of given yourself your own solution. If your 4 month old is getting a bit large for using the seat with the insert, then it is time to try using the seat without the insert. The main purpose of the insert is to help a small baby fit into a seat that will also fit a toddler up until approximately 4 years old. The seat straps should be able to be adjusted to fit a larger baby rear facing quite securely. My own child started using this car seat at about 5 1/2 to 6 months old when the baby capsule became a bit snug and hot to travel in. We never needed to use the insert because of this. Refer to your car seat manual but if your baby is on the larger side I can't see any issues as long as the seat is rear facing. If you're still really concerned, contact the manufacturer.

Yes. The padding is only for comfort, and will not affect safety if removed.

The angle of the seat itself can't be changed in rear facing mode. Check your manual to see if its okay but I would look at putting a towel or similar under the carseat to adjust the angle that way. It may be that your car's seat is quite reclined compared to other models of cars.

Great / I'll give that a go.

Super easy! The first time you will spend a little time looking at the instructions and the threading path which you can easily pass your hand/ arm through (ease of use) and working out how it must be tightened. After that it takes 5 min. My husband and I often change this seat between our cars. This is a great seat - I highly recommend it!

Hi Sarah it comes with the newborn insert x

Thank you. I'll have to go back to the store because they sold it to me without one.

I used it for my new born and found it to be ok, just difficult manoeuvring her in and out of the seat as it is quite compact and the sides seem higher than other car seats. The straps supported her and she was a small newborn. But she hated the car and would scream in this particular seat rear facing... If I had my time again I would use a capsule that you could remove in and out and buy a more expensive car seat when older. I love my safe n sound royale
