Comments: The Britax Parkway SGL is Britax’s entry-price point booster, competing against the Graco TurboBooster. The SG in the model name refers to the seat’s Slide Guard (SG) feature—this keeps a child from submarining out of the seat in a crash. Like other models in this category, the Parkway converts from a high back to a backless booster for older kids (hence the separate ratings from IIHS for each mode).

There use to be two versions of this seat: the SG and the SGL. The SG has been discontinued but we still see it for sale online occasionally. The Parkway SGL includes LATCH connectors (SGL model), which keep the seat anchored when it is unoccupied. It runs $120-$160.  Otherwise, the SGL is the same as the SG. (FYI: the EX version just has an extra pad.)

Comparing the Parkway to the Graco TurboBooster, we’d give Britax the advantage when it comes to seat covers—the fabric Britax uses is much nicer than Graco’s. That said, the Graco TurboBooster’s armrests are bigger than the Parkway’s, which are not adjustable. And the Parkway has a somewhat narrower seat than the TurboBooster, which might mean a tight fit for larger toddlers. As for crash protection, Consumer Reports rated the TurboBooster as better than the Parkway. And the TurboBooster is about $50 less expensive than the Parkway.

In recent years, Britax has tweaked the Parkway SGL with more enhanced side impact protection via deeper head wings as well as the SafeCell technology (seen in Britax’s convertible seats).

The most recent reader feedback on the Parkway is still quite positive, but a few dissenters note that given the Parkway’s width and design, it isn’t the best choice for those trying to fit three booster seats across a back seat for carpools. And cleaning this seat can be a challenge given the design of a small space between the upper and seat cushions that be a collector of all sorts of detritus. You can’t disassemble the seat to clean this area.

Bottom line: this is a good seat, but at a price that is double the Graco TurboBooster, we’d give the Graco seat the edge in overall value.

Rating: A-

Dimensions: 17” wide, 35” high, 14.5” deep.
