Buyer’s Guide: 3 Key Factors to Consider
Weight and Portability
The primary reason you’re looking for a travel seat is ease of carrying. Pay close attention to the product’s weight. Seats like the WAYB Pico are champions here, while convertible options like the Safety 1st Ellaris 3-in-1 will be heavier but offer longer use. Also, look for built-in carry handles or a dedicated travel bag.
Ease of Installation
When you’re tired from travel, you don’t want a complicated installation process. Seek out seats with clear labeling, straightforward LATCH connectors, or features that make a secure fit easier to achieve. A seat you can install correctly in minutes is worth its weight in gold.
Versatility and Long-Term Value
Consider your travel needs. Do you need a seat that works for a newborn and a toddler, like the Safety 1st Crosstown Slim? Or is a dedicated, ultra-lightweight booster for an older child, like the Safety 1st Grand 2-in-1, a better fit? A versatile seat can save you from buying multiple products over time.
