COOSEYA 2-in-1 Toilet Seat Potty Training Seat with Adjustable Step Stool (Purple)
Product description
The essentials
If you’re in the middle of potty training, a step stool-style toilet trainer can make a big difference to day-to-day confidence. The COOSEYA toilet seat and potty training set is designed so toddlers can reach the toilet more safely, with a cushioned seat mat and an adjustable step height.
On paper, it ticks a few practical boxes: a sturdier triangular frame, a wider stepping surface to give more room for shifting feet, and multiple height settings so you can line it up with your bathroom setup. It also uses a waterproof PVC cushion, which is the sort of detail that matters more than you’d think once spills and wash-ups become normal.
What it’s for and how it fits into routines
This product is essentially a 2-in-1 approach to toilet training: it can act as a potty training seat and also double as a step stool. That means it’s not just for the toilet moment—your child can use the step to reach sinks and other higher spots for handwashing or grabbing items.

A quick example: imagine a typical after-play routine. Your toddler needs to get to the toilet without hovering or over-reaching. With the step stool positioned at the right height, they can climb on, sit comfortably on the cushioned PVC surface, and then—when it’s time to wash hands—use the same step to reach the basin. It keeps the “climb” in one consistent place instead of having to swap tools around.
Where it stands out
The main thing you’ll notice is the attention to stability and comfort, at least based on the design described.


- More stable frame, wider stepping area: The solid triangular structure is built to be more stable than simpler step designs, and the stepping surface is widened to give kids more room to turn their feet. That’s especially relevant if your child is still working out balance.
- Height adjusts with multiple hole positions: There are 6 adjustable hole positions, and the step/stool can be raised or lowered by up to 3 inches to suit your toilet height. There’s also mention that the ladder can be adjusted up to a height of 17 inches.
- Waterproof cushioned PVC surface: The waterproof PVC seat cushion is described as having good resilience and a soft touch, with a winter-friendly feel and a cleaner, fresher feel in summer. For potty training, being able to wipe down quickly is one of those “you’ll appreciate it later” features.
- Lightweight and foldable for storage: The product is described as light enough for children to carry by themselves, and it has a foldable design for easier storage.
The practical reality (and a limitation to be aware of)

It’s not a perfect fit for every bathroom setup. The biggest limitation mentioned is that this COOSEYA kids potty training seat is not compatible with square seats. It’s stated to fit standard and extended toilet seats, including V, U and O shapes.
So if your toilet has a square profile, you’ll want to double-check before buying—otherwise you could end up with a mismatched fit and lose the whole point of a stable, secure trainer.
Also, while it’s designed to reduce fear of climbing and falling through stability and a wider stepping surface, nothing like this replaces supervision. Potty training is still a learning phase.

Who it suits best (and who may want to look elsewhere)


It makes sense if you want a single, consistent solution for toilet access and everyday reach tasks. You’ll probably get the most from it if your toddler is close to toilet training readiness and you want something that supports balance (wider stepping surface) and comfort (waterproof cushioned PVC).
It may not suit you if: - Your toilet has a square seat shape, because compatibility is explicitly ruled out. - You’re looking for a more specialised potty system that doesn’t rely on a step/stool approach.
If you tend to change bathroom setups often or have a very unusual toilet shape, you may find that adjustability helps, but the seat-shape limitation is the bigger deal.
What to check before you buy

Before committing, focus on the three things that actually affect fit and safety: 1. Toilet seat shape: confirm it’s compatible (V, U, O, standard or extended), and that it’s not square. 2. Step height needs: use the 6 hole positions to match your toilet height, and check that the range described is enough for your household. 3. Day-to-day cleaning: the waterproof PVC cushion is a positive sign for wipe-downs, but it’s still worth considering how your bathroom routine handles mess.
FAQ
Is it only a potty training seat, or can it be used as a step stool?
It’s described as a multifunctional 2-in-1 unit. It can be used for toilet training and also as a step stool for reaching higher places like a sink.


How do you adjust the height?

The design includes 6 adjustable hole positions. You can raise or lower the ladder by 3 inches, and the ladder can be adjusted up to a height of 17 inches.
Does it work with all toilet seat shapes?
No. It’s stated to fit standard and extended toilet seats (including V, U and O shapes) but it is not compatible with square seats.
Is it quick to put together?
Setup is stated to be quick, around 4–8 minutes, with instructions provided.

Should you expect it to be comfortable for daily use?
The seat cushion is a waterproof PVC cushion designed for soft touch and resilience. It’s framed as warm in winter and clean/refreshed in summer.
Final verdict
Worth buying if you want a stable, adjustable 2-in-1 toilet training seat with a waterproof cushioned surface and a step that can double up for daily reach tasks. It’s a solid match for standard or extended toilet seat shapes (V, U and O), and the adjustable height range should help most households align it properly.
Skip it if your toilet seat is square, because the compatibility limitation is clear. Beyond that, it sits in the practical, mid-range help category for potty training—helpful for access and balance, but still something you’ll want to supervise until your child is fully confident.
