Swing

Hey my boy is 7 months old...20lbs. I need some sort of "chair" for him for indoors. Like when he's at grandma's and she wants to put him down to play or whatever. At home he has his swing (which he will soon outgrow lol) so I guess we are looking for something like that!  A lot them are for infants and he will soon exceed weight requirements. He has a baby Einstein bouncy stationary "walker" type thingy that he doesn't completely love...just wondering if there is anything that you liked for your growing baby! Thank you!
