Limits and specifications are each manufacturer’s own, checked September 17, 2026. A dash means the maker does not publish that number. A highlighted number is simply the highest or lowest value in this table, not a recommendation. Prices are Amazon’s, or the manufacturer’s own where Amazon has no listing, as of the date each was read, and are subject to change; the seller’s price at checkout applies. Photos come from the same Amazon listing or, where Amazon has none, the manufacturer’s site.

Limits and specifications come from each manufacturer’s US website and instruction manual. They are not a fit or safety verdict, and I have not hands-on tested these seats. Follow your seat’s own labels and manual. Amazon links are affiliate links. See my sources and limits.
