Where to put baby once grown out of boppy lounger?

Sa

I’ve been loving the boppy lounger as a place to put the baby, on the couch or on the coffee table 😊

Is there an alternative when baby is gown out of this?

I also have a baby bjorn bouncer but it’s too low to the ground and doesn’t seem very comfy for the baby yet, as he can’t hold his head up yet.
