Jumper for tall 6 month old

No

I would like to get a jumper/activity center for my 6 month old, the only problem is all the ones I have found are for baby’s shorter then 30 in. My baby is 28 in and I don’t want to waste money on something That will only last a month. Does anybody have any recommendations on jumper or activity center for a tall baby? He’s getting bored sitting and laying around Which makes it difficult for me to get anything done around the house
