Question about Joie i-Spin 360 E

Reboarder is a generic name used for those seats that look like baby carriers but are strapped to the base. Such as the Britax Roamer Dualfix or the Ciberx Sirona. They are usually those up to 105 cm.

This one I bought is the E version, i.e. without the infant insert (needed from 40 cm to 61 cm), in fact unlike the normal i-spin 360 the size goes from 61-105 and not 40-105 cm.

The R version (not this one) is the one limited to the back-to-the road position, which is compulsory in Nordic countries up to the age of 4.

The side-impact protection are the two black 'flaps' that snap into place when the belt is tightened. They can be folded manually to rotate the seat. All i-spin 360s have them, but they vary slightly in shape and diemnsion from model to model (I also have an i-spin 360 Signature).
