I Bought This For My 2 Year Old Niece Who Has Charge Syndrome And Prefers Rolling On The Floor To Sitting In Any Chair Ever. I Have Tried All Manner Of Support Chairs And Rockers, Various Materials And Textures And Not A One Has Been Worth Leaving The Floor, Until This One. This Chair Is Perfect. It Is Large Enough That It Doesn'T Restrict Movement But Angled Perfectly So Sitting Back Is Natural. There Is A Block At The Back That Keeps The Chair From Being Rocked Too Far Back And Falling. Also, The Material Seems To Be Very Fun To Scratch And Drool On. I Could Not Be Any Happier. Pros: Size, Support, Construction, Functioncons: None
