Question about weight limits for changing tables

[newmommy0403]

I am looking for a changing table and I've noticed that the few that I've seen that list weight limits (at Target and BRU) the limit is 20 lbs, which seems extremely low to me. I have a Da Vinci (Million Dollar Baby) crib but on their website they don't list weight limits for the changing tables. Is 20 lbs. normal? Does anyone know of any that have higher limits? Thanks for your help.

I have a Pottery Barn changing table and I use it on my 25 lb daughter. It is very sturdy which is why I picked that brand. However, I find that she is too big for it lengthwise so she prefers the crib or floor.
