This toilet trainer is excellent! I have the Baby Bjorn one for our main bathroom and we do love it but I didn't want to pay the same price for a trainer seat for our second, less often used bathroom so figured I'd give this one a try. From the picture it looked very similar to the Baby Bjorn one and when it arrived I realised it is indeed SO similar but you can't compare the price of course, this one is so much cheaper. However, its cheap but excellent value for money. Sometimes you get much more than you pay for! This is certainly the case here.
It's very secure on the toilet, the only difference between this one and the Baby Bjorn one really is that this one doesn't have the clamp wheel underneath but really that doesnt matter as the shape for both trainer seats is mostly what keeps it secure, not so much the clamp. This toilet seat and the BB one are the only ones I've tried that don't move when the child climbs up on it (and I've tried loads!). Your child will easily be able to get on and off and feel secure without the trainer seat sliding all over. If anything I'd say this one will get longer use out of than the BB one because there is more room on the back part of this seat. The BB one has a more raised, curved shape at the back part of the seat where the child's bottom goes. This one doesnt have that raised, curve at the back so it allows more seating room for older toddlers. The seat is super easy to clean, no crevices for germs to breed and its very easy to wipe down completely with antibacterial wipes. This is a fantastic seat and I'd probably just have stuck with this one over the BB one had I known it was so similar and saved a ton of money!
