We purchased this bath seat because our son loves playing in the bath and it was getting a little big for his recliner and the seating position is still more convenient to play. were installed on the same night the ring and to our disappointment the seat slides lot !!! So our son can not stand right in. Yet he is 7 months old and stands very well seated but nothing to do it slides and you have to put it in the seat at all times. We tested several nights but the problem remains the same. Too bad we were all happy to have found this handy ring because it rotates 360 ° but our son did not feel so comfortable in it that eventually we do not use it.
