You are comparing the Safety 1st vs DOONA travel system stroller options for your newborn. Both units support infants from 4 to 30 pounds and click together for easy transit.

Travel System Specs Compared

Overall Configuration

Edge: Safety 1st Smooth Ride Travel System

The DOONA functions as an all-in-one unit that transforms from a car seat to a stroller with a single click. It requires no separate stroller frame, making it a compact, standalone system for your infant. In contrast, the Safety 1st Smooth Ride is a traditional travel system. It pairs a dedicated OnBoard FLX infant car seat with a separate stroller chassis. You must click the car seat into the stroller frame to use it as a stroller. This design offers a distinct stroller experience separate from the car seat itself.

Portability and Weight

Edge: Safety 1st Smooth Ride Travel System

Weight is a critical factor for travel. The DOONA stroller and car seat combination weighs only 17.2 pounds. This light weight makes it significantly easier to lift into overhead bins or carry up stairs compared to most travel systems. The Safety 1st Smooth Ride system is much heavier, weighing 32 pounds. This additional weight provides stability but reduces ease of carrying. If you frequently lift your gear into cars or public transport, the DOONA’s lighter build is a practical advantage for your daily mobility.

Folded Dimensions

Edge: Safety 1st Smooth Ride Travel System

When folded, the DOONA measures 17.4 by 26 by 22.4 inches. Its compact, rectangular shape is designed to fit easily into small car trunks or airplane overhead compartments. The Safety 1st Smooth Ride has different folded dimensions, measuring 17.7 inches in width, 31.5 inches in height, and 19.7 inches in length. The Safety 1st is taller and slightly wider when folded. While both are foldable, the DOONA’s specific footprint is optimized for tight storage spaces and air travel requirements.

Canopy and Sun Protection

Edge: Safety 1st Smooth Ride Travel System

Both systems include canopies to shield your baby. The DOONA features a water-repellent canopy with UPF 50+ sun protection, offering high-level defense against ultraviolet rays. It also includes a 3-layer side impact protection system. The Safety 1st Smooth Ride includes an extra-large canopy with a flip-out visor and a large peek-a-boo window for airflow. While it does not specify a UPF rating in the data, it provides ample coverage. The DOONA offers certified sun protection ratings, whereas the Safety 1st focuses on size and visibility.

Stroller Capacity and Growth

Edge: Doona All-in-One Infant Car Seat & Stroller

Consider how long you will use the stroller portion. The Safety 1st Smooth Ride stroller holds a child up to 50 pounds. This allows you to use the stroller frame for a toddler after the infant car seat expires at 30 pounds. The DOONA is strictly an infant system. It is suitable from 4 to 30 pounds. Once your child outgrows the weight limit, the DOona cannot be used as a stroller. If you want one unit that grows with your child into toddlerhood, the Safety 1st offers a higher weight capacity for the stroller portion.

Included Accessories and Base

Edge: Safety 1st Smooth Ride Travel System

The DOONA package includes a LATCH car seat base, an infant insert, head support, and a vehicle seat protector. It is a complete kit for installation and comfort. The Safety 1st Smooth Ride includes the OnBoard FLX infant car seat and the stroller frame. The data does not explicitly list a base or additional inserts in the features, though it mentions trays for parents and children. The DOONA provides more specified accessories for immediate use, including the base and protective elements, ensuring a ready-to-go setup for travel.
