Car Seats

The best booster seats

A booster has one job: put the adult seat belt where it belongs on a small body. Everything else on the box is upholstery.

Our picks at a glance

A booster does not restrain a child. The vehicle's own lap-and-shoulder belt does that — the booster simply raises and positions the child so the belt crosses the middle of the shoulder and sits low across the hips, rather than across the neck and the soft abdomen.

That makes booster shopping unusually simple to reason about. The right booster is the one that produces a correct belt fit on your child in your car. Features, fabrics and cup holders are real conveniences but they are not the product's function, and a cheap booster with good belt geometry beats an expensive one without it.

How we chose

Because belt fit is the whole job, we ranked on belt geometry and on how hard a booster makes it to get that fit wrong. IIHS publishes belt-fit ratings for boosters, and we point you to their tool for your specific model rather than reprinting a rating we could not read from the source.

  • Belt guide quality. A shoulder guide that holds the belt at mid-shoulder and does not let it slip toward the neck, and lap horns that keep the lap belt on the hips.
  • Adjustment range. How many headrest positions, and how well the guide tracks the child as they grow.
  • High-back and backless flexibility. A booster that converts covers a wider span and is the more useful purchase for most families.
  • Lower-anchor attachment, where offered — it stops an empty booster becoming a projectile and holds the booster in place between journeys.
  • Whether it also harnesses. A combination seat with a 5-point harness first, booster later, is the right answer for a child who is not yet reliable in a belt.
  • Published range and fabric chemistry, read from the manufacturer's own page.

We have not crash-tested any of these seats — no consumer publication in the US does, and every seat here has already passed the same federal standard. What we did was read each manufacturer's specification page and manual, record every figure against the page it came from, check each model against NHTSA's recall database, and confirm it is currently sold. The dates of those checks are printed on every product below. Our full method is on the methodology page.

The default booster: highback to start, backless later, open belt guides that position the belt where it needs to be, and a price that makes a second one for the other car easy.

A booster has one job — hold the vehicle's lap and shoulder belt in the right place on a body too small for it. Judged on that, the TurboBooster 2.0 is hard to beat for the money. It covers 40-100 lb and 43-57 in from age four, converts from highback to backless as the child grows, and the open-loop belt guides make it easy to see at a glance whether the shoulder belt is sitting across the middle of the shoulder rather than on the neck. The highback mode weighs 9 lb and the backless 5 lb, so it moves between cars and into a grandparent's easily. It expires ten years from manufacture. What it lacks is side-impact structure relative to the Britax and Chicco, and the padding is thin on long drives. Do not skip the highback stage just because backless is easier: the highback provides the head support and belt routing a younger child still needs.

What works

  • Open belt guides make correct belt position obvious
  • Cheap enough to buy a second for the other car
  • Light in both modes, so it travels well

What to weigh

  • Less side-impact structure than the premium boosters
  • Thin padding on long journeys
  • Tops out at 100 lb, below the 120 lb boosters

The booster a child will not complain about on a four-hour drive, with double-layer head protection and a quick-release LATCH that stops it flying around empty.

Booster comfort is a safety feature in disguise: a child who is comfortable stays seated properly, and a child who is not slouches, tucks the shoulder belt behind their arm, or argues about the whole thing. The KidFit ClearTex Plus has the best padding in this group, plus DuoGuard double-layer side protection around the head. The range is 40-100 lb in highback mode and 40-110 lb backless, for children at least four years old and 44-57 in. The quick-release LATCH is worth more than it sounds — it holds the empty booster to the seat so it is not loose in the cabin, while still detaching in a second. Costs more than the Graco, and 44 in is a higher entry height than some, so check your child clears it.

What works

  • Best padding here — children genuinely object less on long drives
  • DuoGuard double-layer head protection
  • Quick-release LATCH keeps the empty booster secured

What to weigh

  • Costs noticeably more than the Graco
  • 44 in minimum height is higher than some boosters
  • Bulkier, so three across is harder

Goes to 120 lb and 63 in, which is the booster to buy if your child will still need one after most boosters have run out.

Plenty of children reach a booster's weight or height limit before the vehicle belt actually fits them, and the AAP's marker for that is roughly 4 ft 9 in and age eight to twelve. The Highpoint pushes the ceiling out to 40-120 lb and 38-63 in, converting to a backless booster from 48-120 lb, so it covers the awkward late stage where a child is too big for a standard booster and still too small for the belt alone. It also has three layers of side-impact material. It is large, it costs more, and if your child is average-sized they may outgrow the need before they outgrow a cheaper booster — in which case the extra range is money spent on headroom you never use. For a tall eight-year-old, it is exactly the right seat.

What works

  • 120 lb and 63 in — covers the late stage most boosters miss
  • Three layers of side-impact material
  • Converts to backless for the final stretch

What to weigh

  • Large in the back seat
  • Premium price
  • The extra range is wasted on an average-sized child

Expandable side wings and a 40-120 lb range, for the child who has outgrown a booster in width rather than height.

Boosters are usually outgrown in one of three directions and the one nobody designs for is width — a broad or solidly built child can be squeezed by the side wings long before they hit the weight or height limit. The Monterey's sides expand, which is the specific fix, and the range runs 40-120 lb and 38-63 in so it also covers the late stage. It is a well-built, fairly heavy booster and costs above the Graco. If your child is comfortable in a standard booster, this is not the one to buy; if they keep complaining that the sides dig in, it is the obvious answer.

What works

  • Expandable sides fit broad-shouldered children
  • Range runs to 120 lb and 63 in
  • Solid construction

What to weigh

  • Heavier than most boosters
  • Costs more than the mainstream options
  • Unnecessary if a standard booster already fits comfortably

A forward-facing harness that becomes a booster, for the child who is heavy enough for a booster but not yet mature enough to sit in one properly.

Weight is not the only thing that decides booster readiness — a booster only works if the child sits upright and leaves the belt alone for the whole journey, and plenty of four- and five-year-olds who meet the weight limit cannot do that yet. A harness-to-booster keeps them in a five-point harness until they can. The MyFit runs a forward-facing harness from 26.5-65 lb and then a belt-positioning booster from 40-100 lb, so the switch happens when the child is ready rather than when the seat runs out. It is bulky and it does not rear-face at all, so it is a second or third seat rather than a first. If you are staring at a booster wondering whether your child will actually stay put in it, buy this instead.

What works

  • Keeps a not-quite-ready child in a harness past the booster weight limit
  • 65 lb harness limit is high
  • ClearTex fabric

What to weigh

  • No rear-facing mode — this is never a first seat
  • Bulky in the back seat
  • Booster mode stops at 100 lb

The five-step belt fit test

Before you buy, and again every few months afterwards, run this on your child in your car. It is the same test a certified technician uses, and it decides whether the booster is doing its job — or whether your child no longer needs one.

  1. 1.Can the child sit all the way back against the vehicle seat with their knees bending comfortably at the edge of the cushion?
  2. 2.Does the lap belt sit low across the hips and upper thighs, touching bone, rather than riding up onto the stomach?
  3. 3.Does the shoulder belt cross the middle of the shoulder and the center of the chest — not the neck, not sliding off the arm?
  4. 4.Can the child stay seated properly for the whole trip, without slouching, leaning out or tucking the shoulder belt behind them?
  5. 5.Are their feet supported so they are not tempted to fidget out of position?

If all five are true without the booster, the child is ready to use the belt alone. If any one fails with the booster, the booster is the wrong one, is set at the wrong height, or the child needs a harnessed seat a while longer. The full explanation, including where combination seats fit, is in car seat versus booster seat.

High-backBackless

If a booster will spend its life moving between cars, buses and grandparents, look at the folding and inflatable travel options in best travel booster seats — they solve a real problem that a full-size booster does not.

Frequently asked questions

When can my child stop using a booster?

When the adult seat belt fits correctly without it, which is usually somewhere between 4 ft 9 in and 5 ft tall and often between ages 10 and 12. Use the five-step test: the child sits all the way back, knees bend at the seat edge, the lap belt sits low on the hips, the shoulder belt crosses mid-shoulder and mid-chest, and they can stay in position for the whole trip. All five have to pass without the booster.

Are backless boosters safe?

Yes, when they are used in a seating position where the vehicle's own head restraint supports the child's head and the belt geometry produces a correct fit. What a backless booster does not give you is shoulder-belt guidance, side structure, or anywhere for a sleeping child to lean, which is why a high-back is the better default for younger children. Backless boosters are excellent for travel, carpools and older children.

Can I use a booster with a lap-only belt?

No. A belt-positioning booster works by routing a lap-and-shoulder belt, so a lap-only belt gives it nothing to position and leaves the child restrained only across the abdomen. If a seating position has a lap-only belt, the correct answer is a harnessed seat that can be installed there, or a different seating position. Check your vehicle manual — some older center positions are lap-only.

What do IIHS booster ratings actually measure?

How well the booster routes an adult seat belt on a child-sized test dummy across a range of vehicles — where the lap belt sits and where the shoulder belt crosses. Ratings run from BEST BET down, and they are specifically about belt fit rather than crash performance. Because IIHS blocks automated access to its database, we do not reprint per-model ratings here and instead link their tool so you can check your exact model.

Should I buy a combination seat with a harness instead?

If your child is on the cusp, yes. A combination seat has a 5-point harness for the earlier years and converts to a belt-positioning booster later, so it covers the transition without a second purchase and lets you delay the booster until the child can genuinely sit still. The trade-off is bulk and price. If your child is already reliable in a belt and tall enough, a dedicated booster is simpler and cheaper.

Does my booster need to attach to the car with LATCH?

It does not need to for the child's protection — the vehicle belt over the child is what restrains them. It is still worth having, for two reasons: an unoccupied booster that is anchored cannot become a projectile in a crash or a hard stop, and an anchored booster stays put between journeys so it is in the right place when the child climbs in. Where a booster offers lower-anchor attachment, use it.
