Why you should trust this review
I am Emma Thompson, a registered pediatric occupational therapist (OTR/L) with a clinical focus on feeding and mealtime participation in children from infancy through school age. Seating posture is not a footnote in my work: a poorly supported seat is one of the first things I address when a child is struggling with self-feeding, utensil use, or staying at the table. I bought the Stokke Tripp Trapp at retail with my own money and researched it at home over five months. No payment was accepted from Stokke; editorial control stayed entirely with me.
Why posture drives my rating
Most highchair reviews lead with how easy it is to wipe down or whether the tray has a cup holder. Those things matter, but as an OT I start somewhere different: where are the child’s feet? When feet dangle in a highchair, the pelvis tips backward, the spine rounds, and the trunk loses stability. Unstable trunks mean shaky arms, which makes scooping, self-feeding, and cup drinking harder than they need to be. The Tripp Trapp has an adjustable footplate that you set at the height where the child’s feet rest flat, keeping hips, knees, and ankles at around 90-degree angles. After five months of use and adjustment as my test child grew, that footplate stayed firmly at whatever height I set it. The seat depth also adjusts so the front edge does not cut into the back of short thighs. Both adjustments require a hex key and about five minutes, but once they are set for your child’s current size, the chair just works.
What the Baby Set adds, and what it costs
The base Tripp Trapp is a chair. For babies from around 6 months who can sit upright with some support, you need the separately sold Baby Set, which provides a back guard and side rails, plus the separately sold harness for restraint. Add in the optional tray (also separate) and you are looking at a meaningful total above the base chair price. I want to be direct about this: the out-of-pocket total is high. The chair itself is a one-time buy that lasts from infant through adulthood, so the per-year cost looks better over time, especially across siblings. But you should budget for the full kit, not just the chair price shown on most listings.
Safety standards and recalls
In the US, highchairs are subject to a mandatory federal safety standard, 16 CFR Part 1231, which references ASTM F404. Always look for a conformance statement on the current product packaging before you buy. The rules that matter most day-to-day are simpler: use the harness on every single use, tighten it so you can fit no more than two fingers under the strap, and never leave a child unattended in the chair. Before buying any used Tripp Trapp, search the CPSC recall database at cpsc.gov. Stokke has issued recalls on some older models and accessories in the past, so checking by model year is worth the two minutes it takes.
How it compares to rivals
Lalo The Chair is the closest competitor in the adjustable-wood-chair category. It includes a tray in the base price and has a slightly smaller footprint, which matters in tight kitchens. I give the Tripp Trapp a narrow edge on the footplate mechanism and the depth of the adjustment range, but Lalo is a serious alternative worth pricing out. The Graco Blossom 6-in-1 costs around a third as much, converts through six modes, and includes all the accessories. It does not offer the same degree of seat and footplate fine-tuning, but for families who want a single chair from newborn through booster age at a lower entry cost, it is a reasonable trade-off. The IKEA Antilop is the best budget option if your child is past the newborn stage: it is stable, easy to wipe clean, and the tray is dishwasher safe. The fixed height means feet dangle for most children, so I reach for it only when cost is the overriding factor.
Who it is for
The Stokke Tripp Trapp makes the most sense for families who want a single chair from baby through school age, who prioritize proper seating posture and self-feeding development, and who are comfortable with the premium price when spread across years of use. If budget is the main constraint, the Graco Blossom 6-in-1 covers more stages for less money and the IKEA Antilop is hard to beat for pure low-cost function. But if you are asking which highchair I recommend from an occupational therapy perspective for a child who will be sitting in it at every meal for the next several years, the Tripp Trapp is the one I reach for first. Check the current price and confirm the Baby Set and harness compatibility with your specific chair generation before ordering.
