Playful bath seat. It fulfills its safety function and games like my daughter. The intention of a sliding shelf was good but unfortunately too complicated handling especially with baby in the seat. No worries especially with suction cups. The seat would be worth as on some slip bath seats but it seems that this is a desire to SMOBY which estimates that this would be too irritating for baby's skin (information received from the contact center following a request for additional information made directly through the manufacturer's website).
