We have the Baby Trend Sit and Stand. IT works great for our just turned 4 year old and soon to be 1 year old. Contrary to many reviews, the child can sit in the back while the child upfront is in the recline position. Lots of storage, is a little bulky, but I figure you only fold it maybe twice a day, but push it around with teh kids in it a lot more than that.
Another thing I like about it is that I am 6'1" and can push my girls in this without kicking the back of the stroller!
