The box only indicates 6mo+. Oddly there is not a weight recommendation or limit posted on the box. I have not opened it to see if there is more info inside. I'll do so here in a bit and if so I'll let you know. Thanks!
just so you know we have one of these and my two year old neice (24 lbs) and my one year old (20lbs) both love it! Even my nefew (4) i think he weighs like 50lbs gets in one! Hopes this helps!!!!!
