5 Best Booster Seats of 2021

Kid Booster Seat Safety Standards

High back booster seat

  • These are designed for kids ages 4-7 or until your child reaches the height or weight limit. They’re commonly known as the safest booster seat for children because of Side Impact Protection padding, and adjustable headrest and harness. High-back booster seats come with adjustable harnesses to fit comfortably across your child’s shoulders and the straps are connected to keep your kid safe using a push button latch system similar to most standard car seat belts.

Backless kid booster seat

  • These are lightweight seats that protect your child using your car’s seat belt across their shoulder and lap. The backless booster seat doesn’t include a harness since it’s intended for kids ages 8 to 12 years old that have outgrown a high-back kid booster seat. The booster seat should position your child with your car’s headrest and seat belt safely.

If you’re not sure which booster seat your kid needs, use the ‘5 Step Booster Test.’ If you answer ‘no’ to any of the five questions, your child is required to be in a booster seat.


  • Does your kid sit back correctly in your car’s seat?
  • Do your kid’s knees sit at the edge of your car’s seat comfortably?
  • Does the seat belt touch the top of your kid’s thighs and not the stomach?
  • Is the shoulder belt centered between the shoulder and chest?
  • Can the child stay seated like this for the whole trip?

Factors to Consider Before Buying a Booster Seat

  • Safety – The safest and best kid booster seats offer Side Impact Protection, and are made with energy-absorbing foam impact cushions on both sides of the booster seat. Most booster seats also include extra headrest and torso protection with extra padding. No matter which booster seat you choose, it should meet the federal safety standard – FMVSS 213 to meet the U.S. design and performance for kid booster seats and car seats.
  • Comfort – Kids should love their booster seat as much as you do. Most booster seats are made with high-quality double-foam padding for a comfy and safe seat. For maximum comfort, the booster seat should be easily adjustable. You should be able to easily adjust the harness and headrest to properly and comfortably fit your child. Look for a few ‘nice to have’ comfy features including cup holders, hidden storage and armrests.
  • Easy to clean – Messes are bound to happen when you’re on the go. You should be able to clean any spills on the plastic parts of the booster seat with mild soap and cool water. Look for a kid booster seat that includes a removable, machine washable booster seat cover for your convenience and a thorough clean.
  • Age and booster seat stages – Your child is constantly growing. Consider buying a 2-in-1 kid booster seat that grows with them. Popular booster seats include an adjustable harness to use when your child is smaller, and a removable backrest to fit your child as they grow older. You’ll also want to consider height, weight and age limits for each booster seat to pick the right one that matches your child’s growth.


3 Reasons Kids Need Booster Seats

  • Prevention and Peace of Mind

    According to the American Society for the Positive Care of Children (ASPCC), kid booster seats reduce the risk of serious injuries by 45 percent. With the right booster seat, you’ll have peace of mind knowing that even if there’s road trouble, your child is secured in the care safely with the right belts and protective padding.

  • Law Requirement

    By law, you’re required to protect your child in the car. Every state has different child restraining system laws when using car seats, booster seats and seat belts. 36 states require children 7 and younger to be in a child restraining system when riding in a car. Be sure to review the Insurance Institute for Highway Safety to understand your state’s latest laws and requirements for your child.

  • Growth

    Children outgrow standard baby and early toddler car seats quickly. They’ll eventually outgrow the car seat harness, headrest and leg room. To keep your child riding safely and comfortably, you’ll want to get a booster seat for them to stay safe and secure in your car.

Your child’s car safety is key when you’re on the go. There are many kid booster seat options to choose from to keep them safe, secure and comfortable. As you pick out your child’s booster seat, keep requirements and leading recommendations in mind.
