When parents begin preparing for introducing solids, they spend a lot of time thinking about what foods to offer, whether to do baby-led weaning (BLW) or start with purees, and how to prepare food safely. But one important piece of the puzzle is often overlooked: where your baby is sitting.
Your baby’s high chair is not just a place to contain them when they’re eating. Research consistently shows that mealtime is about more than just food, and there are important developmental and psychological benefits to giving your baby a seat at the table from the very beginning.
Making sure your baby is in the right high chair obviously won’t make your baby a better eater (if only parenting purchases worked that way!), but a well-designed chair can provide the stability and support to make mealtimes easier and safer.
Why High Chair Setup Matters For BLW
Regardless of the starting solids approach you choose, positioning matters. Babies are still developing core strength, coordination, and the ability to sit upright for extended periods. A supportive seat allows them to focus their energy on the most important task at hand: reaching and grasping food, bringing things to their mouth, exploring new foods, and generally learning how mealtime works.
A baby who is slumped, leaning, or sitting with unsupported feet may have to work harder to maintain position. What makes it tricky is that babies come in different sizes, and a one-size-fits-all approach to high chairs will not work. Pick a high chair that can adjust based on what YOUR baby needs.
What Is 90-90-90 Posture in a BLW High Chair?
You may have heard feeding specialists refer to “90-90-90 positioning” when discussing high chairs.
This means a seated position where:
- Hips are positioned at approximately a 90 degree angle.
- Knees are bent at approximately a 90 degree angle
- Feet have support (ankles are resting at approximately a 90 degree angle).
The goal is not to create a perfectly measured position every time your baby eats. Babies grow quickly (and real life is rarely that precise). Instead, understanding 90-90-90 positioning gives you a helpful framework for thinking about stability. One of the most commonly overlooked pieces of this equation is foot support. A secure footrest gives your baby a stable base, and a supported and stable baby will be better able to focus on participating actively in the meal.
Safety before starting solids
Before worrying about the details of high chair positioning, safety comes first. A few important reminders:
- Your baby should show signs of readiness for solids, which typically occurs around 6 months of age.
- Always supervise your child while eating. Don’t turn your back! Choking is silent, and fast.
- Make sure your baby is always upright during meals.
- Follow manufacturer instructions on high chairs, including using safety harnesses.
- Always ensure your high chair is stable and placed on a safe surface.
- Make sure you are following safe food preparation and choking prevention guidelines.

What To Look For in a High Chair for BLW
There are many high chairs on the market, and the options can quickly become overwhelming. When helping families think through this decision, I encourage them to focus less on trends and more on function.
1. Adjustable foot support
A good footrest is one of the most important features to consider. Babies grow rapidly, and an adjustable footrest allows the chair to continue supporting your child as their legs lengthen. And if your child tends to run petite (like mine!), it can be hard to find a stable and comfortable high chair that fits.
2. Adjustable seat depth and height
A chair that adjusts in height and depth as your child grows is often more useful than one designed for only one stage. Seat depth matters because babies and toddlers come in different shapes and sizes! Height adjustments also allow your child to transition from tray feeding to sitting closer to the family table.
3. Stability and safety features
A high chair should feel sturdy and secure. Look for a design that feels well-constructed with a stable base and an appropriate harness system. It should meet all applicable safety standards. The Momcozy DinerPal High Chair is constructed with FSC-certified beechwood and FDA approved plastic, has a 5-point harness, and silicone rubber feet. It also meets all applicable safety standards.
4. Easy cleaning
Starting solids is messy. Having a removable tray, wipeable surfaces, and machine-washable fabrics can make the endless cleanup of this phase of parenting much easier. The Momcozy DinerPal High Chair has both a dishwasher-safe tray and a machine-washable harness which can simplify post-meal cleanup.
5. Ability to grow with your child
This is a personal recommendation. One of the hardest parts of parenting is all the STUFF. Babies need so much stuff, and it can feel like your home is overflowing and cluttered. From a minimalist standpoint (both for space and environmental reasons), it is helpful to find products that can transition beyond the infant feeding stage and continue supporting independence through toddlerhood. I love the Momcozy DinerPal High Chair because it is designed with this “grow-with-me” philosophy in mind. It starts off as a more classic tray feeding high chair, but then transforms into a child seat (with baby set), a dining chair (with harness), and then it can become both a learning tower/step stool and an adult chair.
Stage by stage adjustment tips
Around 6 months
When babies first begin solids, they usually need the most support physically. This is the stage where features like a secure harness, appropriate seat depth, foot support, and tray positioning are especially important.
9 months to 3 years
As your baby grows and practices, they will become more confident eaters. At this point, children are usually participating in family mealtimes more consistently, and adjustable height settings can help create a more integrated mealtime experience. And eventually when your child no longer needs the baby seat and tray, you can adjust the seat depth of the high chair into a more “grown-up” configuration to create more space and legroom for older children.
Toddler and preschool years
Toddlers love to help! The Momcozy DinerPal High Chair also transforms into a learning tower or step-stool to give your growing child some age-appropriate independence in the kitchen and around the home.

The bottom line
When choosing a high chair, I encourage you to think beyond the first few months of feeding. The best high chair for BLW (and for introducing solids in general) is not necessarily the one with the most features or highest price tag. It is one that provides a safe, stable, comfortable place for your child to learn to eat and participate in family meals.
When choosing a high chair, look beyond the tray. Consider posture, foot support, adjustability, ease of cleaning, and whether the chair can grow alongside your child.
A thoughtfully designed high chair can support more than feeding. It can help create a comfortable place where your child learns, explores, and becomes more independent.
