Price and rating as shown on Amazon when we collected them. Both change.

The Maxi-Cosi Kore Pro i-Size is a forward-facing high-back booster for children of 100–150 cm, listed at £189.99 and sitting at number 10 in this guide. It is the same R129 100–150 cm class as seats selling for £59.99, so the £130 difference buys the ClickAssist buckle light, the height and width adjustment on the headrest handle and the Plus side protection system — not a wider range of children. The weight figure is where the listing stops making sense: the spec table files a 'Maximum Weight Recommendation' of 36 Hundredths Pounds, which is 0.36 kg, in the same table that gives a 15 kg minimum weight.

The review numbers do not reconcile either. The star breakdown runs 64 five-star, 14 four-star, 13 three-star, 1 two-star and 8 one-star — 100 ratings in total, against a headline count of 93 — and those 100 ratings average 4.57 by the star counts shown, while the headline rating reads 4.2. Everything on this page is taken from the Amazon listing as it stands; we have not tested the seat.
