It features extra-plush padding, a hand-washable fabric cover, and a vehicle-friendly design to prevent seat marks, but lacks a built-in shoulder belt guide—the belt routes over the armrest. This booster is well-suited for travel, carpooling, and three-across installations in compact vehicles, though user reviews note that padding is minimal for longer trips.","url":"https://kidsy.co/products/cosco-topside-backless-booster-car-seat-leo-2","brand":"Cosco Kids","condition":"used","product_category":"Baby & Toddler > Baby Transport > Baby & Toddler Car Seats > Booster Seats","weight":"3","item_weight_unit":"lb","age_group":"kids","image_url":"https://kidsy.co/cdn/shop/files/cosco-topside-backless-booster-car-seat-leo-1739041.jpg?v=1757561780&width=823","additional_image_urls":[],"images":[{"id":"img-1783486548801-0","url":"https://kidsy.co/cdn/shop/files/cosco-topside-backless-booster-car-seat-leo-1739041.jpg?v=1757561780&width=823","width":494,"height":494,"alt_text":"Cosco Topside Backless Booster Car Seat (Leo) product image (primary)","position":1,"attributes":{"mood":["neutral","functional"],"text":"COSCO","style":["minimalist","utilitarian"],"colors":[{"color":"light gray","context":"main seat upholstery and armrests"},{"color":"dark gray","context":"lower base and armrest accents"},{"color":"medium gray","context":"background floor tiles"}],"labels":["upholstered padded seating surface","raised padded armrests","contoured seat well","stitched seam lines","embroidered COSCO logo on front center","two-tone construction","textured plastic base"],"flat_lay":true,"confidence":"high","description":"Top-down view of a two-tone padded booster seat with raised armrests and a visible COSCO logo, placed on a tiled floor.","season_occasion":["everyday"],"complementary_products":[]},"variant_ids":["50352260546840"]}],"price":"25.99 USD","sale_price":"8.49 USD","availability":"out_of_stock","group_id":"9775695364376","listing_has_variations":"false","variants":[{"sku":"COSCO-884392570415-818280932665-GENTLYUSED","url":"https://kidsy.co/products/cosco-topside-backless-booster-car-seat-leo-2?variant=50352260546840","image":{"id":"img-variant-50352260546840","url":"https://kidsy.co/cdn/shop/files/cosco-topside-backless-booster-car-seat-leo-1739041.jpg?v=1757561780&width=823","width":494,"height":494,"alt_text":"Cosco Topside Backless Booster Car Seat (Leo) variant image","position":1,"variant_ids":["50352260546840"]},"price":{"value":25.99,"currency":"USD"},"title":"Cosco Topside Backless Booster Car Seat (leo)","option1":"Default","sale_price":{"value":8.49,"currency":"USD"},"variant_id":"50352260546840","availability":"out_of_stock"}],"item_group_title":"Cosco Topside Backless Booster Car Seat (Leo)","size_system":"US","gender":"unisex","shipping":"Free shipping on orders over $75 across the USA.
