I have the Fisher-Price Home & Away 3-in-1 high chair.
A big concern of mine was space since we live in a studio apartment and things are tight. This is the smallest high chair they had a babies r us. All the others seemed huge to me.
I like that I can move it around very easily. The wheels work well and you can lock them in place when using the chair.
I think it is a good height. You can also adjust it to make it lower if you need to. I haven't used it as a portable high chair but you can. It will also become a booster seat for a toddler.
I recommend going to the store and checking out different chairs. Especially if size is a big factor for you.
