jumper for 4 month or exersaucer?

Hi my baby turned 4 months two days again and she's bored with laying on her back and her bouncers. Is there anyway I can put her in a jumper or exersaucer? She does try to stand up when I put her feet on a flat surface so that's why I think she'll be great in a jumper. Please all opinions are accepted I just want to be sure.
