Highchair safety is one of those things most parents assume they have covered until something goes wrong. A wobbly chair, a loose harness, feet dangling with no support. These small oversights can add up to real risk at mealtimes.
The good news is that improving your highchair safety is straightforward once you know what to look for. In this highchair safety guide, we will walk you through everything from proper positioning and harness use to choking prevention and the most common mistakes parents make. Whether you are setting up a brand new highchair or wondering if your current setup needs a safety refresh, you are in the right place.
Why Highchair Safety Matters
Highchair-related injuries are more common than most parents realise. In Australia, the ACCC reports that feeding aides including highchairs account for 25 per cent of nursery furniture injuries in New South Wales alone. Falls are the leading cause, usually because the harness was not used or was too loose.
In the United States, Safe Kids Worldwide reports that an average of 24 children per day are treated in emergency departments for highchair or booster seat injuries. The vast majority of these are preventable.
The numbers are confronting, but improving highchair safety comes down to a handful of avoidable mistakes: skipping the harness, placing the chair near a table edge the child can push off, or leaving your little one unattended. Get the basics right and you dramatically reduce the risk.
Beyond preventing falls, proper highchair safety practices also affect how well your child eats. A baby who feels unstable will fidget, lean on the tray for support, and have a harder time focusing on food. Safe positioning and comfortable positioning go hand in hand.
The 90-90-90 Positioning Rule
If there is one concept from paediatric occupational therapy that every parent should know, it is the 90-90-90 rule. It is the gold standard for safe, comfortable seating at mealtimes, and it is simpler than it sounds.
The idea is that your child sits with three joints at roughly 90 degrees:
- Hips at 90 degrees, with their bottom pushed back against the seat
- Knees at 90 degrees, with thighs supported by the seat
- Ankles at 90 degrees, with feet flat on a stable surface
Most highchairs, including the popular IKEA Antilop, do not come with a footrest. That means your baby's feet dangle in mid-air with nothing to push against. Adding a highchair footrest is the single most effective way to achieve the 90-90-90 position. It is a change many parents say they notice within the first few meals. Read our full guide on why a footrest matters for your highchair.
Highchair Safety Checklist
Use this checklist before every meal. It takes less than 30 seconds and covers the essentials that prevent the most common highchair accidents.
If your highchair has wheels, make sure they are locked before placing your child in the seat. The American Academy of Pediatrics recommends checking that you can hear and feel the locking mechanism click into place every time you set up the chair.
It is also worth periodically checking for loose screws, cracked plastic or worn straps. The ACCC has issued recalls on several highchair models in recent years, so a quick check at productsafety.gov.au is a sensible habit.
Common Highchair Safety Mistakes
Even attentive parents can fall into common highchair safety traps. Knowing what to watch for makes a real difference.
Mistake 1: Skipping the harness
This is the number one cause of highchair falls. It is tempting to skip the buckle for a quick meal, especially when your toddler protests. But children are quick, unpredictable, and stronger than they look. The Safe Kids Worldwide foundation found that the majority of highchair injuries result from falls where the harness was not used or was too loose. Always buckle up.
Mistake 2: No footrest
When feet dangle, your child has no base of support. They compensate by leaning on the tray, fidgeting, or bracing their legs against the chair frame. This is uncomfortable, makes self-feeding harder, and can contribute to poor posture during eating. A footrest solves this in minutes.
Mistake 3: Chair placed too close to a table or wall
Children push. It is what they do. If the highchair is close enough to a table, counter or wall, your child can push off with enough force to tip the chair backwards. Always leave a clear gap on all sides.
Mistake 4: Wrong tray position
The tray should sit at roughly chest height for your child. Too high and they strain to reach food. Too low and they hunch forward, which compresses the airway. Many highchairs have a fixed tray position, but you can adjust the effective height by using a cushion to raise your child slightly in the seat.
Mistake 5: Food sizes not matched to developmental stage
Offering food that is too small, too round, or too hard for your child's stage is a choking hazard. As a general rule, foods should be soft enough to squish between your fingers and cut into age-appropriate shapes. See our baby-led weaning guide for detailed food preparation advice.
Choking Prevention During Mealtimes
Good highchair safety and choking prevention go hand in hand. The position your child sits in directly affects their ability to manage food safely.
When a child is slouched, leaning to one side, or has their head tilted back, their airway is partially compressed. This makes it harder to chew thoroughly and increases the risk of food entering the windpipe. The 90-90-90 position we covered earlier keeps the airway open and aligned, which is the foundation of safe eating.
Beyond positioning, here are the key choking prevention strategies for mealtimes:
- Always supervise. Be present and attentive for every bite. Choking can happen silently.
- Sit upright. Your child should be sitting up straight in the highchair, not reclined.
- Avoid high-risk foods. Whole grapes, cherry tomatoes, popcorn, whole nuts, raw carrot sticks and hard lollies are common choking hazards for young children.
- Cut food appropriately. For babies starting solids, offer finger-length strips. For toddlers, cut round foods into quarters lengthways.
- Do not rush. Let your child eat at their own pace. Hurrying increases the chance of swallowing large pieces.
- Learn the difference between gagging and choking. Gagging is loud, normal and protective. Choking is silent and requires immediate action. Read our full gagging vs choking guide for a detailed breakdown.
As part of your overall highchair safety preparation, every parent should complete an infant first aid course that covers choking response. Knowing the difference between a back-blow sequence and when to call emergency services could save your child's life. Contact your local St John Ambulance or Red Cross for courses in your area.
When to Start Using a Highchair
Most babies are ready for a highchair around 6 months of age, which typically coincides with the start of solid foods. However, the right time depends on your child's development rather than a strict age cutoff.
Look for these readiness signs before moving your baby into a highchair:
- Good head and neck control. Your baby can hold their head steady and upright without it flopping or wobbling.
- Sitting with minimal support. They can maintain an upright posture for at least 60 seconds when placed on a flat surface, without using their hands to prop themselves up.
- Interest in food. They watch you eat, reach for food, and open their mouth when food comes near.
- Loss of tongue-thrust reflex. They no longer automatically push food out of their mouth with their tongue.
If your baby can sit in the highchair but still slumps to one side or needs a lot of support, they may not be quite ready. A highchair cushion can help with positioning for babies who are nearly there but need a little extra support, though it should not be used as a substitute for true sitting readiness.
Most families use their highchair from around 6 months through to age 2 or 3. During this window your child will go from first purees (or first finger foods if you are following a baby-led weaning approach) all the way to independent eating with utensils.

Making Your IKEA Highchair Safer
The IKEA Antilop is one of the most popular highchairs in the world for good reason. It is affordable, easy to clean and meets safety standards. But like most budget highchairs, it has a few gaps that are worth addressing.
Here is how to improve your Antilop highchair safety and turn it into the best possible setup for your child:
Add a footrest for 90-90-90 positioning
The Antilop does not include a footrest, which means your child's feet dangle with no support. A bamboo highchair footrest clips onto the existing legs and immediately gives your child a stable base to push against. This is the single most impactful safety and comfort upgrade you can make. Paediatric occupational therapists consistently recommend foot support for safe eating posture.
Use a placemat for a safer feeding surface
A silicone placemat creates a non-slip surface on the Antilop tray. Bowls and plates stay put, food does not slide into your child's lap, and the raised edges help contain spills. It also makes cleanup faster, which means less time fussing and more time for your child to eat at their own pace.
Consider a cushion for secure positioning
For babies who are on the smaller side or who tend to slide forward in the smooth plastic seat, a highchair cushion adds grip and padding. It helps your child sit more securely without relying on the harness alone to hold them in place.
Protect your floors with leg wraps
While leg wraps are primarily about protecting your floors from scratches, they also add a small amount of grip to the chair legs, reducing the chance of the chair sliding on smooth surfaces like tiles or hardwood.
