An Alternative to my 1 year old son's bouncer

So I have a 1 year old and he adores his bouncer, however it's getting to the point where his knees are touching the floor and obviously he is too big for it. He uses it to go to sleep he enjoys rocking himself to sleep. Is there anything on the market that can allow him to do the same thing but is made for his 22lbs and up

Sincerely a mommy in deire need!!
