We're adding a guest suite to our home and plan to buy a Toto Drake non-ADA toilet. We have a toddler grandchild and another "on the way." Our adult children live far away, but when they come to visit it would be nice to have a toilet seat that little ones could use. I saw the Kohler Transitions seat at a showroom and think it would be a nice addition to the guest bathroom. It's a "seat within a seat" and is sized for both adults and small children.

Will the Transitions seat fit on the Drake? Has anyone done this and do you like the seat?
