The Clek Oobr is a high-backed booster you can use without the back when your child outgrows it. This steel frame booster has the best combined crash test results, and it has a rigid LATCH system to secure the booster to the car. We like the adjustable headrest, comfortable armrests, and easy-to-clean fabric. 
This option is heavy and more cumbersome than the competition, making it a poor choice for carpooling and travel. Still, we think it makes up for this heft with impressive crash test results, quality construction, and the ability to quickly and easily secure the booster to the car to avoid it becoming a flying projectile when little ones aren't in the car. The Clek is an excellent choice for families with safety on the brain who are less concerned with switching cars or carrying for travel or carpooling.

This versatile, inexpensive seat buckles to an adult chair, can work with or without a tray, and folds up for the road. But it’s tougher to clean and less comfy than our pick.

Why We Love the Fisher-Price Healthy Care Deluxe Booster Seat

bazaarvoice

The UPPAbaby Alta is a high-quality booster seat with better than average crash test results and some nice features for kid comfort. We like the LATCH connection of this booster, which keeps it from free-floating in the car, and kids like the adjustable headrest that provides comfort at almost any height level. This seat has ample padding, a useful recline feature, and a cup holder. It also sports a machine washable cover, which is a bonus every parent will love. 
This seat is heavier and unlikely to be a good fit for travel or the carpool group. However, it is reasonably narrow, making it a potential option for 2+ seats across a vehicle row. With better-than-average crash test results and a comfortable cockpit, this seat will please passengers and parents alike. The reasonable price tag is just a bonus.
