Its slim 17-inch width enables three-across seating in most vehicles, and it features an automotive-grade steel frame with ComfortPlus memory foam padding. However, Consumer Reports crash tests have shown significant shell cracking in rear-facing tests, and installation can be difficult without additional support, with users also noting the harness requires rethreading for height adjustments.","url":"https://kidsy.co/products/diono-radian-3r-all-in-one-convertible-car-seat-black-storm-1","brand":"Diono","condition":"used","product_category":"Baby & Toddler > Baby Transport > Baby & Toddler Car Seats > Convertible Car Seats","material":"Steel frame, foam padding, fabric cover","item_weight_unit":"lb","age_group":"infant","image_url":"https://kidsy.co/cdn/shop/files/diono-radian-3r-all-in-one-convertible-car-seat-black-storm-7986388.png?v=1764031352&width=823","additional_image_urls":["https://kidsy.co/cdn/shop/files/diono-radian-3r-all-in-one-convertible-car-seat-black-storm-6835392.jpg?v=1764031353&width=823","https://kidsy.co/cdn/shop/files/diono-radian-3r-all-in-one-convertible-car-seat-black-storm-3096459.jpg?v=1764031354&width=823","https://kidsy.co/cdn/shop/files/diono-radian-3r-all-in-one-convertible-car-seat-black-storm-8290612.jpg?v=1764031355&width=823"],"images":[{"id":"img-1781228389121-0","url":"https://kidsy.co/cdn/shop/files/diono-radian-3r-all-in-one-convertible-car-seat-black-storm-7986388.png?v=1764031352&width=823","width":716,"height":716,"alt_text":"Diono Radian 3R All in One Convertible Car Seat (Black Storm) product image (primary)","position":1,"attributes":{"mood":["practical","safe"],"text":"diono","style":["modern","functional","minimal"],"colors":[{"color":"black","context":"main body, outer shell, base, cup holders"},{"color":"light gray","context":"headrest, shoulder pads, seat cushion"},{"color":"red","context":"harness release button and small fabric tags"},{"color":"white","context":"embroidered logos and label text"},{"color":"yellow","context":"small strap indicator on harness"}],"labels":["black fabric outer shell","light gray padded headrest","light gray shoulder pads","light gray seat cushion","five-point harness straps","red harness release button","black plastic base","left cup holder (black plastic)","right cup holder (black plastic)","embroidered white logo 'diono' on headrest","embroidered white 'diono' on side","multicolor instruction label on side","contoured seat shell shape","foam padding visible in seat areas","yellow strap buckle indicator"],"flat_lay":false,"confidence":"high","description":"Child car seat in black with light gray padded inserts, five-point harness, two black cup holders, and visible safety instruction label on the side.","season_occasion":["everyday","travel"],"complementary_products":[]},"variant_ids":["52158975475992"]},{"id":"img-1781228389121-1","url":"https://kidsy.co/cdn/shop/files/diono-radian-3r-all-in-one-convertible-car-seat-black-storm-6835392.jpg?v=1764031353&width=823","width":716,"height":716,"alt_text":"Diono Radian 3R All in One Convertible Car Seat (Black Storm) product image 2","position":2,"attributes":{"mood":["cheerful","vibrant","safe"],"text":"1 2 3 fits 3 across","style":["playful","family-friendly","modern"],"colors":[{"color":"pink","context":"center car seat upholstery and seat trim"},{"color":"magenta","context":"ambient lighting on ceiling and around rear window area"},{"color":"blue","context":"left car seat upholstery and harness padding"},{"color":"red","context":"right seat upholstery or trim and small heart motif on shirt"},{"color":"white","context":"ceiling/headliner, plush toy body, headrests"},{"color":"black","context":"seat belt webbing and harness buckles"},{"color":"denim blue","context":"children jeans"}],"labels":["child car seat with five-point harness (left)","booster or high-back car seat (center, pink)","vehicle seat with lap-sash seat belt (right)","five-point harness straps","lap-sash seat belt fastened across passenger","plush pig toy with rounded feet","panoramic sunroof interior with colored ambient lighting","pink padded seat upholstery (center)","blue padded seat upholstery (left)","red padded seat upholstery or trim (right)","white vehicle headliner","mesh or perforated white headrests","children seated in rear row","small bow hair clip","small red heart motif on shirt (right)","denim jeans worn by children","studio or staged in-car shot","bright colored ambient LED lighting (purple/pink)"],"flat_lay":false,"confidence":"high","description":"Three children seated across the rear of a car in three different child seats;

In 2 of 2 rear-facing tests with the CRABI 12-month-old dummy installed with lower anchors, there was significant cracking in the shell from the rear to front. In 1 of 1 rear-facing tests with the CRABI 12-month-old dummy installed with the 3pt belt, there was cracking from the rear of the shell to near the crotch buckle slots... there is concern that the seat should not have such large cracking with the smallest dummy size (12-month CRABI) that it is intended for."},{"type":"thread","title":"User frustration with rear-facing installation and safety doubts","ref_id":"r_e_3","thread":{"url":"https://www.reddit.com/r/CPST/comments/1j6xk45/very_unhappy_with_diono_car_seat_as_rear_facing/","title":"Very unhappy with Diono car seat as rear facing","subreddit":"CPST"},"excerpt":"Very unhappy with Diono car seat as rear facing.
