We have a Alessi toilet, the problem was that fit on a designer WC not everyone (or not really) children toilet seat. The FlexiFit is recommended in every way, with security also for standard toilets. It can be adapted by the two gripping arms on the underside individually. The handling is easy and once set, keep the arms securely in place. Still, he can also by a child with a grip slightly off and hang up. The FlexiFit then holds without wobbling, slipping and chattering on the toilet, so that the short to climb onto the toilet safely and independently. When our toilet you can close the toilet lid even despite FlexiFit hook, or the whole incl. Toilet seat open (for the men). He is obviously very convenient, because our son has accepted him immediately. Visually, it is discreet, the workmanship is very good. Is convenient that it is open at the back. This is actually for flexible adaptation, facilitated but on top of that "wipe Popo" the mandatory. Highly-thought-product, value more than justified!
