"This is a remarkably secure seat that is great for toddlers. It is adjustable, easy to clean and pops on and off with one hand and no effort at all making it great for a shared bathroom or travel. It is light and not too bulky. Best of all, it is evidently quite comfortable, as our little one will sit there for ages. It will work for a range of ages, as we started him on it when he was about 8 months old and he's been routinely pooping on the toilet since. Baby Bjorn really got their toilet-training products right."
