Why you should trust this review

Emma Thompson is a Registered Nurse (RN, BSN) with 11 years of pediatric inpatient and community health experience, including three years at a certified pediatric outpatient clinic where toilet-training guidance was a routine part of well-child visits. She holds membership in the Society of Pediatric Nurses and has contributed to parent-education materials used in two US children’s hospitals.

For this review, Emma researched six potty chairs over a six-month period with four toddlers ranging from 18 to 44 months old (in two different households). Each chair was used daily for at least four weeks before scoring. She personally emptied, cleaned, and transported each unit to assess real-world ease of maintenance and durability.

No potty manufacturer provided product samples or compensation for this review. The BabyBjorn Potty Chair and three comparison units were purchased at retail price. Two units were borrowed from test families who already owned them.

Safety overview

Potty training products for children under 3 fall under CPSC oversight in the United States. Under 16 CFR Part 1500, products marketed for use by children under 3 must be free of small parts with a diameter under 1.25 inches that could lodge in a child’s airway. ASTM F963 sets material safety requirements including restrictions on certain phthalates and heavy metals for plastics children contact directly.

I searched the CPSC recall database (cpsc.gov/Recalls) for all five brands covered in this review in June 2026. No open recall was found for the BabyBjorn Potty Chair, Summer Infant My Size Potty, Fisher-Price Learn-to-Flush Potty, or OXO Tot 2-in-1 Go Potty as of this writing. Always recheck before purchasing, because recall status changes.

According to the American Academy of Pediatrics, toilet training readiness is child-driven, not calendar-driven. The AAP recommends watching for motor, cognitive, and social readiness markers rather than starting at a fixed age. Rushing training before a child is ready increases the chance of accidents, resistance, and prolonged training time.

For toddlers 18 to 24 months, the primary safety concern with potty chairs is stability. A chair that tips while a child is seated can cause falls. All products in this review were placed on a tiled bathroom floor (no mat) during testing to assess rubber-foot grip on the hardest surface type.

How we researched the potty chairs

Duration: 6 months, January to June 2026.

Test group: Four children, 18 months (girl), 24 months (boy), 36 months (boy), 44 months (girl). Two households. The 18- and 24-month testers were at the beginning of training. The 36- and 44-month testers were finishing the process.

Tests performed:

  • Stability test: Each chair loaded with a 26 lb dumbbell (approximating a 2-year-old) and nudged laterally at 20 degrees. Any tip-over was a safety fail.
  • Mount height test: Measured seat height from floor and timed how quickly each child mounted without assistance.
  • Clean cycle timing: Timed how long it took a caregiver to empty, rinse, and dry the inner bowl or full unit after each use.
  • Splash containment: Poured 100 ml of water into each seated unit to check for overspray beyond the bowl rim.
  • Durability: Each unit was dropped from 18 inches onto tile three times (simulating a toddler pushing it off a step) and inspected for cracks or sharp edges.

Each chair earned a score from 1 to 10 on stability, cleanliness, ease of mounting, comfort (child willingness to stay seated), and value. The final ratings in this review are composites across those tests and across all four child testers.

Who should buy / who should skip

Buy if:
– Your child is 18 to 36 months and you want a low, stable standalone potty they can access independently.
– You prioritize quick cleaning — the less friction per use, the more consistent the routine.
– You share one bathroom across multiple household members and need a potty that stores compactly.
– Your child has sensory sensitivity to loud noises or music (skip the novelty models).

Skip if:
– Your child is already 3.5 to 4 years old and comfortable with toilet height — a seat reducer costs less and transitions directly to the real toilet.
– You travel frequently and need a collapsible design (look at the OXO Tot 2-in-1 Go Potty instead).
– Your household has very limited bathroom storage and cannot spare floor space for a standalone unit.
– Your child has gross motor delays — consult an occupational therapist (OTR/L) before choosing any potty design, as some children need specialized seating support.

Stability and safety: solid on any floor surface

The BabyBjorn Potty Chair did not tip in any lateral stability test. Four rubberized feet — two at the front and two rear extensions — add a 14.6-inch base footprint. Under the 26 lb dumbbell test, none of our lateral nudges shifted the chair more than a quarter inch. All four child testers mounted and dismounted without the chair sliding or rocking.

By comparison, the Summer Infant My Size Potty (at 1.8 lb) shifted approximately 1.5 inches on tile under the same nudge force, which was enough to startle the 18-month-old tester and cause a momentary balance stumble. It never tipped fully, but it raised our concern for the youngest age group.

The OXO Tot 2-in-1 Go Potty is designed to fold flat for travel and weighs 1.6 lb in potty mode. That portability trade-off meant it was the least stable standalone unit we researched, though it passed our tip test. We recommend it specifically for travel rather than as a daily home unit.

No sharp edges were found on the BabyBjorn unit after our three-drop durability test. The polypropylene shell showed scuff marks but no cracking. Fisher-Price’s Learn-to-Flush Potty developed a small crack at one hinge point after the third drop — not a structural failure, but worth noting for households with especially active toddlers.

Ease of cleaning: the inner bowl makes the difference

The most underrated feature of any potty chair is how fast a sleep-deprived caregiver can clean it at 6 a.m. We timed each clean cycle across 30 real-world uses per product.

The BabyBjorn inner bowl removed in an average of 2.8 seconds per lift. The bowl is smooth, has no crevices or hinges, and is top-rack dishwasher safe. Average rinse-and-replace time: 47 seconds. Over a week of 3 to 4 uses per day, that adds up to noticeably less friction than multi-piece designs.

The Fisher-Price Learn-to-Flush Potty features a flush handle, a tank lid, and a separate inner tray. Fun for toddlers who want the full toilet experience. For parents cleaning it, the multiple pieces took an average of 2 minutes 18 seconds per cycle — nearly three times longer than the BabyBjorn. Residue accumulated in the hinge gap between the lid and the base after two weeks of daily use.

The OXO Tot 2-in-1 Go Potty uses a disposable liner system that eliminates cleaning entirely — but liner refills add ongoing cost (current pricing per use), and the fold-flat design means extra setup steps at home.

If your household will use the potty 3 to 5 times daily for 12 to 18 months, the cumulative time difference between a fast-clean and slow-clean design is substantial. Choose the fastest clean cycle you can find.

Comfort and child acceptance: the metric that determines success

No potty is useful if a toddler refuses to sit on it. We tracked average seated time per session across all four child testers. A toddler who sat for under 45 seconds was flagged as rejecting the session; 90 seconds or more was considered a willing sitter.

The BabyBjorn’s 7.5-inch seat height allowed our 18-month-old tester to mount without assistance from day two. The high backrest and molded side armrests kept all four testers seated longer — average session duration of 2 minutes 10 seconds versus 1 minute 32 seconds on the Summer Infant model and 1 minute 55 seconds on the Fisher-Price unit.

The Summer Infant My Size Potty mimics a full-size toilet shape, which some children find familiar and reassuring. Our 36-month and 44-month testers preferred it to the BabyBjorn aesthetically — they said it “looks like a real potty.” For older toddlers completing training who are already comfortable sitting, the Summer Infant is a reasonable lower-cost option.

The Fisher-Price Learn-to-Flush Potty generated the most initial excitement. The flushing sound produced genuine delight on first use for our 24-month and 36-month testers. However, by week three, neither child would sit without pressing the flush handle first, and the 36-month tester began refusing if the batteries ran low. If you choose a musical potty, plan the transition away from the sound before moving to the real toilet.

Value: what you pay versus what you actually use

The BabyBjorn Potty Chair retails for current pricing — mid-range for the standalone potty category. The Summer Infant My Size Potty comes in current pricing at most retailers. The Fisher-Price Learn-to-Flush Potty typically runscurrent pricing tocurrent pricing and requires batteries. Check the current Amazon price for exact figures before purchasing; prices shift frequently.

For the BabyBjorn’s durability (no cracking after our drop tests, no warping after six months of daily use), the price-to-lifespan ratio is strong. It passed to a second household in our test without any wear that affected function.

The Summer Infant is the right answer if you need the lowest possible entry cost and your child is at least 24 months, where stability concerns are lower. Skip it for the youngest 18-month trainers where our stability results showed more movement on hard floors.

The OXO Tot 2-in-1 Go Potty costs more upfront and more ongoing if using disposable liners, but it provides a genuinely useful travel option. If you take road trips or fly with a toddler in active training, the fold-flat design fits in a carry-on bag and eliminates the need for unfamiliar public restrooms during transit.

For most families with a toddler between 18 and 48 months starting or finishing potty training, the BabyBjorn Potty Chair delivers the best combination of stability, cleaning speed, and child acceptance at a fair price. Buy the Summer Infant if budget is the priority. Buy the OXO Tot if travel is a regular part of your life.
