A friend of my bought a family seat from One Step Ahead and she loves it! She did advise to get the wooden one even though it's more money b/c she heard the plastic one cracks. I'm looking to purchase this one myself as we too have a potty seat adapter and this seems so much nicer. Sorry I don't have any personal experience w/using this one yet but you can read the reviews and see what you think. I hope this helps you.
