Solid, not wobbly or rickety (I am sure you could rock fairly forcefully and make some wobble but that would not be how I would imagine a person would normally sit in a stool - even if you are sitting down hard or  gettig up quickly). We have 3 kiddos. The 3 and 4 year old can climb on them without toppling the stool. The 14 month old does not pull them over - even when she cruises around them. The stool seat swivels 180 degs and swivels smoothly. We have a counter height island and the back of the stool does hit the counter top. We just have to be careful so we don't ding the counter top. Would re-order.
