It converts from rear-facing (5–50 lbs) to forward-facing (22–65 lbs) to high-back booster (up to 120 lbs), featuring a slim-fit profile for 3-across seating, a reinforced steel frame, and ComfortPlus memory foam. However, child passenger safety technicians (CPSTs) frequently note that the seat is difficult to install correctly, has a high misuse rate, and its height/weight limits are often overstated; many recommend alternative seats for easier installation and better booster performance.","url":"https://kidsy.co/products/new-diono-radian-3r-all-in-one-convertible-car-seat-black-storm","brand":"Diono","condition":"new","product_category":"Baby & Toddler > Baby Transport > Baby & Toddler Car Seats > Convertible Car Seats","item_weight_unit":"lb","age_group":"kids","image_url":"https://cdn.shopify.com/s/files/1/0805/9325/6728/files/diono-radian-3r-all-in-one-convertible-car-seat-black-storm-7986388.png?v=1764031352","additional_image_urls":["https://cdn.shopify.com/s/files/1/0805/9325/6728/files/diono-radian-3r-all-in-one-convertible-car-seat-black-storm-6835392.jpg?v=1764031353","https://cdn.shopify.com/s/files/1/0805/9325/6728/files/diono-radian-3r-all-in-one-convertible-car-seat-black-storm-3096459.jpg?v=1764031354","https://cdn.shopify.com/s/files/1/0805/9325/6728/files/diono-radian-3r-all-in-one-convertible-car-seat-black-storm-8290612.jpg?v=1764031355"],"images":[{"id":"img-1784245856304-0","url":"https://cdn.shopify.com/s/files/1/0805/9325/6728/files/diono-radian-3r-all-in-one-convertible-car-seat-black-storm-7986388.png?v=1764031352","width":800,"height":800,"alt_text":"New Diono Radian 3R All in One Convertible Car Seat (Black Storm) product image (primary)","position":1,"attributes":{"other":{"summary":"Product shot with a clean isolated background, soft frontal lighting, minimal shadows and tight crop centered on the car seat.","observations":[{"key":"Shot composition","kind":"feature","value":"Centered three-quarter frontal view of the car seat with slight right-facing orientation, isolated on a plain transparent or neutral background.","regions":[],"evidence_status":"direct"},{"key":"Lighting and shadow","kind":"feature","value":"Even diffuse lighting from the front with soft shadows beneath and slight shadowing inside the seat cavity.","regions":[],"evidence_status":"direct"},{"key":"Image quality","kind":"feature","value":"High-resolution product image with clear edges and no visible compression artifacts.","regions":[],"evidence_status":"direct"}]},"colors":[{"name":"matte black","part":"main shell fabric","regions":[{"x":0.2,"y":0.04,"width":0.6,"height":0.92,"confidence":"high"}],"subject":"product","description":"Deep matte black fabric covering the outer shell and base with a low-sheen finish.","estimated_hex":"#0B0B0B"},{"name":"light gray","part":"padded inserts and headrest","regions":[{"x":0.42,"y":0.11,"width":0.2,"height":0.13,"confidence":"high"},{"x":0.36,"y":0.48,"width":0.28,"height":0.26,"confidence":"high"}],"subject":"product","description":"Mid-tone neutral gray padding with a smooth fabric appearance used for headrest and seat cushions.","sampled_hex":"#929395","estimated_hex":"#B6B6B6"},{"name":"bright red","part":"harness buckle and small tags","regions":[{"x":0.47,"y":0.62,"width":0.08,"height":0.06,"confidence":"high"},{"x":0.69,"y":0.28,"width":0.04,"height":0.06,"confidence":"high"}],"subject":"product","description":"Small bright red accents on the central buckle cover and a narrow fabric tag on the shell.","estimated_hex":"#D32F2F"},{"name":"gloss black","part":"plastic cup holders","regions":[{"x":0.1,"y":0.72,"width":0.18,"height":0.12,"confidence":"high"},{"x":0.72,"y":0.72,"width":0.18,"height":0.12,"confidence":"high"}],"subject":"product","description":"Glossy black plastic used for the two cylindrical cup holders.","estimated_hex":"#0F0F0F"},{"name":"white","part":"printed brand logo","regions":[{"x":0.46,"y":0.08,"width":0.12,"height":0.07,"confidence":"high"}],"subject":"product","description":"White printed logo on the upper headrest area.","estimated_hex":"#FFFFFF"}],"product":{"summary":"Forward-facing view of a convertible car seat showing high-back shell, removable padded inserts, five-point harness, two plastic cup holders, visible brand logos and warning/instruction label on the side.","observations":[{"key":"High-back shell","kind":"feature","value":"Tall contoured high-back shell with a deep central seating area and pronounced side wings extending from the head region down to the base.","regions":[{"x":0.2,"y":0.04,"width":0.6,"height":0.92,"confidence":"high"}],"evidence_status":"direct"},{"key":"Headrest pad","kind":"feature","value":"Detachable-looking padded headrest insert in light gray with stitched contouring and a rounded rectangular central pad.","regions":[{"x":0.42,"y":0.11,"width":0.2,"height":0.13,"confidence":"high"}],"evidence_status":"direct"},{"key":"Five-point harness and buckle","kind":"feature","value":"Black web harness straps with shoulder pads, converging to a central buckle;
