This is as safe as houses, rear facing is so much safer and this will last years even if on bigger centiles, alot of isofix swivels will only last a year or so as they have a height and weight limit x

Our little boy grew out of his MaxiCosi i-Size at 6 months 😳 since then we’ve had the Joie Signature I-Spin XL and had no issues at all, it can go up until he’s 12 if needs be!

We love our joie 360 ispin x

There’s the axkid spin kid and avionaut stardust that are supposed to be quite good seats but obviously check out the weight limits in case your little one is higher centiles as they will outgrow it quicker. We have an axkid one 3 which I love and should last him hopefully until he goes into a high backed booster (but he’s not too high centiles)
A lot of the extended rear facing ones even though they don’t spin have fairly low sides so still easy to get little one in and out x

If you are specifically looking at the one you posted though I think you can get a discount code on boots at the moment so would be cheaper x

We have the one you posted for toddler and baby will likely go into it when she outgrows her infant seat. Personally we have the cloud z and use seat belt for one car and isofix for the other (we still take it in the house with her in it).
