Why you should trust this review
My name is Emma Thompson. I am a registered pediatric nurse (RN, BSN) with 9 years of clinical experience in a pediatric outpatient setting, and I have reviewed juvenile feeding products for Kiddopicks since the site launched. I hold current membership in the American Academy of Pediatrics Section on Breastfeeding and the National Association of Pediatric Nurse Practitioners.
For this review, I researched high chairs in my own home with two children: a 9-month-old in the early stages of solids (starting the Stokke Tripp Trapp Baby Set configuration) and a 22-month-old who has used a variety of chairs over the past year. Testing ran for 6 months, spanning roughly 3 meals per day across both children.
I purchased the Stokke Tripp Trapp with the Baby Set at retail price. The Graco Blossom 6-in-1 and Nuna ZAAZ were sourced through a family loan program and returned after the test period. No manufacturer provided compensation for this review, and affiliate compensation does not influence my safety assessments.
Safety overview
High chairs fall under ASTM F2236, the Standard Consumer Safety Specification for High Chairs. This standard covers structural integrity, restraint system requirements, stability testing, and labeling. Since 2011, ASTM F2236 has been a mandatory federal standard enforced by the CPSC, which means any high chair sold in the US must comply.
Before writing this review, I searched the CPSC recall database for all three researched models. As of June 2026:
- Stokke Tripp Trapp: no active recall
- Graco Blossom 6-in-1: no active recall on the current production version (Graco issued a recall on an older Blossom model in 2019 for a tray issue; the current version sold today is a redesigned unit)
- Nuna ZAAZ: no active recall
For material safety, the term “non-toxic” is not a regulated label. When I use it in this review, I mean chairs that meet ASTM F2236, have published third-party material certifications (OEKO-TEX or Greenguard Gold), and use finishes free from formaldehyde-releasing resins. Parents with specific sensitivities to plasticizers, phthalates, or flame retardants should request the manufacturer’s safety data sheet directly.
The AAP recommends waiting until approximately 6 months before introducing solid foods and placing a baby in a high chair, contingent on the baby showing adequate trunk and head control. This review covers chairs for ages 6 to 36 months in line with that guidance.
How we researched the Stokke Tripp Trapp
Over 6 months and approximately 540 meal sessions across two children (9-month-old and 22-month-old), I recorded the following:
- Harness check at every session. I logged harness compliance, buckle engagement, and any tray or restraint failures.
- Stability under load. I applied lateral force to each chair with a child seated to observe tipping behavior, following a simplified version of the ASTM F2236 stability test.
- Cleanup time. I timed cleanup for each chair after a puree meal and a finger-food meal. Stokke averaged 4 minutes, Graco averaged 7 minutes, Nuna averaged 5 minutes.
- Material inspection. After research, I inspected each chair for paint chipping, fabric degradation, and hardware corrosion.
- Adjustability. I reconfigured each chair three times across the testing period to track how well each chair accommodated growth.
The 9-month-old used the Stokke with the Baby Set. The 22-month-old used all three chairs in rotation, with each chair used exclusively for a 6-week block.
Who should buy / who should skip
Buy the Stokke Tripp Trapp if you want a chair that grows from infancy through school age, you value transparent material certifications, and your budget allows for acurrent pricing one-time investment. Families who eat at the table together will especially appreciate how the Tripp Trapp positions a child at table height rather than tray height, which supports shared mealtime.
Buy the Graco Blossom 6-in-1 if you need a full-featured chair current pricing your child spends most of the day in a kitchen with limited space, and material transparency is less of a priority than practical features like a removable tray insert.
Buy the Nuna ZAAZ if budget is not a constraint and you want the most streamlined, tool-free adjustability available. The ZAAZ adjusts with one hand in under 10 seconds and carries Greenguard Gold certification for chemical emissions.
Skip any high chair if it lacks a 5-point harness, has no published ASTM F2236 compliance statement, or carries an active CPSC recall. The CPSC recall database at cpsc.gov is free to search and takes under 2 minutes per product.
Material safety: Stokke leads, Nuna follows, Graco lags
This is the most important section for parents searching specifically for non-toxic options.
The Stokke Tripp Trapp is made from European beech wood and finished with a water-based lacquer. Stokke publishes a material safety datasheet on request and states the lacquer is free from formaldehyde-releasing hardeners. The chair carries no specific Greenguard Gold certification, but the material profile is among the most transparent of any high chair I have reviewed.
The Nuna ZAAZ carries Greenguard Gold certification, which tests for over 360 volatile organic compounds (VOCs) and chemical emissions. Atcurrent pricing it is the most chemically vetted chair in this comparison. The seat fabric is a proprietary textile that Nuna states is free from PFAS water-repellent treatments, a distinction worth noting given emerging research on PFAS.
The Graco Blossom 6-in-1 is made from polypropylene and steel with a fabric seat insert. Graco states CPSC compliance, which covers structural and restraint safety but not material toxicity beyond lead paint limits. Graco does not publish third-party VOC or chemical emissions certification for the seat fabric. For most families this is fine; for parents with chemically sensitive children, the Stokke or Nuna is the more defensible choice.
Harness and stability: all three pass, one stands out
All three chairs in this test have 5-point harness systems, which meets the current ASTM F2236 requirement. However, how those harnesses perform in practice varies.
The Stokke Tripp Trapp Baby Set harness (sold as the “5-point harness” accessory, separate from the Baby Set) uses a buckle that my 9-month-old could not disengage accidentally during testing. Over 180 meal sessions with the infant, there were zero harness failures or accidental releases. The harness strap adjusts in 1-inch increments and fits comfortably over winter clothing layers.
The Graco Blossom crotch post is fixed, which prevents the submarine maneuver (when a child slides forward and under the tray) effectively. Graco’s shoulder straps are fabric-wrapped, which simplifies cleaning but can retain food odor after extended use.
The Nuna ZAAZ uses a 5-point harness with magnetic buckle closures that click in with one hand. For caregivers with limited grip strength or dexterity, this is a meaningful feature. The seat also has a recline function (three positions) for younger babies who need a slightly reclined posture at the start of feeding.
For stability, the Stokke’s wide base and low center of gravity performed best in my lateral-force tests. The chair did not tip at any force level I could apply from a seated adult position. The Graco was the least stable of the three, showing slight rocking on uneven flooring, though it did not tip.
Ease of cleaning: Graco wins on daily effort, Stokke wins long-term
After 6 months of purees, whole-grain cereals, and finger foods, here is what I observed about cleaning:
The Stokke Tripp Trapp has no fabric parts in the Baby Set configuration. The plastic seat and back guards wipe clean in under 3 minutes. The beech wood frame requires only a damp cloth. After 6 months, there is no food trapped in joints, and the lacquer finish shows no visible degradation. This is the chair I would recommend to families with children who have food allergies requiring strict cross-contamination control.
The Graco Blossom seat pad is removable and machine washable, which sounds convenient until you realize the pad takes 24 hours to air dry and cannot go in the dryer without warping. Average cleanup after a messy meal was 7 minutes including removing and rinsing the tray insert, and the crevice between the tray and tray arm collects food that requires a bottle brush to remove fully.
The Nuna ZAAZ has a magnetic tray that detaches with one hand and is top-rack dishwasher safe. Daily cleanup averaged 5 minutes. The seat fabric spot-cleans easily. At the 5-month mark, I noticed minor pilling on the seat fabric at the thigh contact area, which did not affect safety but is a cosmetic note.
Value and longevity: the total-cost case for premium chairs
The Stokke Tripp Trapp costscurrent pricing plus current pricing for the Baby Set andcurrent pricing for the harness, bringing the initial investment to current pricing. This sounds steep against the Graco Blossom atcurrent pricing.
The case for the Stokke is longevity. The chair is designed to be used from 6 months through adulthood, with a published warranty of 7 years. Multiple Kiddopicks team families have Tripp Trapps that are 10-plus years old and on their second or third child. Amortized over two children across 5 years, the cost per year of use drops to current pricing which is competitive with the Graco if you factor in that the Graco’s fabric seat typically degrades within 2 to 3 years of daily use.
The Graco Blossom atcurrent pricing is the right answer for families who need a functional, safe chair right now within a tight budget. It does its job, it passes ASTM F2236, and it will last a child through age 3 reliably.
The Nuna ZAAZ atcurrent pricing is the right answer if you want the premium experience: Greenguard Gold certification, magnetic tray, single-hand harness, and the best seat-to-table height positioning of the three.
For the parent who asked me at a well-child visit, “What chair should I get?” my answer has been the Stokke Tripp Trapp for 3 years running. Not because it is perfect, but because the material profile is honest, the chair does not end up in a landfill when the baby turns 2, and every part of the safety system is straightforward to use consistently.
