Booster Seat Buying Guide

By: Saundra Latham on April 04, 2018

What the best Booster Seat has

  • Good safety ratings and features. The Insurance Institute for Highway Safety (IIHS) rates all boosters on how well they position a child for proper seat-belt placement. Among combination and high-back boosters, parents should also look for side-impact protection and energy-absorbing foam. LATCH that helps keep an unused booster from becoming a projectile in a crash is a nice extra.
  • High height and weight limits. The National Highway Traffic Safety Administration (NHTSA) recommends that children stay in a booster seat until they properly fit the car's seat belt only, sometime between age 8 and 13. Proper belt fit means the lap belt lies snugly across the upper thighs, not stomach, and the shoulder belt stays snug across the shoulder and chest instead of crossing the neck or face. If you're buying a combination booster seat for a younger child, look for a seat with a high height and weight limit for harness use -- children are safer secured by a five-point harness than seat belts alone.
  • An easy-to-use harness or belt guide. If you're buying a combination booster seat for a younger child, the harness should be easy to position and buckle. On belt-positioning booster seats for an older child, look for clearly marked belt paths that allow the seat belt to operate normally. Ideally, your child should be able to independently buckle himself into the seat.
  • Adjustable harness slots and crotch straps. Combination booster seats for younger children should have harness straps that are easily adjustable to account for growth. There should also be at least two -- preferably three -- slots for the crotch strap, no part of which should be under the child.

Know before you go

Is your child big enough for a booster seat? After children are too big to sit in a rear-facing seat, NHTSA recommends keeping kids in a forward-facing seat with a five-point harness as long as allowed by the seat's manufacturer. After that, but generally not until at least age 4, children are ready for a belt-positioning booster, always in the back seat. While some manufacturers list minimum weights for belt-positioning boosters as low as 30 pounds, experts agree that using a five-point harness for as long as possible is the safest bet. A combination seat that converts from a forward-facing seat with a harness to a belt-positioning booster can give parents the best of both worlds.

Do you travel frequently, or will your child often be carpooling with friends? Some combination and high-back booster seats are heavy and bulky -- not exactly ideal for kids who will be switching vehicles. Choose a lightweight, easy-to-tote seat for traveling or carpooling. Backless booster seats are particularly worth a look for ease of use and portability.

Is space tight in your vehicle? You may have a smaller vehicle with a cramped back seat, or perhaps you need to fit three car seats in one row. Look for a seat with a narrow width to maximize space. Just test it first to make sure it doesn't put the squeeze on your child.

Do you frequently take long trips? You may be past the days of driving aimlessly in hopes of getting your child to nap, but boosters should still be comfortable enough to accommodate a short snooze. At a minimum, look for an adequately padded seat and adjustable armrests. If your child is a good car sleeper, consider a high-back booster with deep head wings to minimize head slump. Cup holders are also a nice bonus, but ensure they're big enough to be functional -- they should at least accommodate a standard water bottle.

Are you picky about how the seat looks? Many boosters come in an array of fabric choices, from neutral shades to vibrant colors. However, to find the widest selection, you may need to shop online. Major retailers often only stock a few options for even the most popular booster seats. Kids who may otherwise balk at booster seats due to their age may be more cooperative if they pick out a fabric or style they like.

Can you rely on your child to keep the seat clean? While spit-up and diaper blowouts may be a thing of the past, your booster seat will still need to stand up to grime, spilled drinks and snacks, and even occasional car sickness. Look for a seat cover that's easily removable and machine washable -- most are, but not all.

Does your vehicle have contoured seats or low seat backs? A booster seat needs to fit well in your vehicle and grip the seat surface properly. If you have low seat backs or no headrests, a high-back booster will better protect your child in a crash.

Do you want to use the seat for more than one child? Like all car seats, booster seats expire. Unlike infant or toddler seats, however, you could be using a booster with a single child for four or more years. This makes it especially crucial to check the seat's expiration date if you hope to use it again. Some models expire six years after they're manufactured, but a few have longer shelf lives -- check before you buy.
