Like a bouncer chair? Or a jumper? Bouncer chair where there is head and neck support they can use once they have some head/neck control, so now would be fine, but a jumper you need to wait until he can sit up unassisted. So 5-6 months old. I think I started putting my LO in the jumper when he was about 4 months old but only for 10 minute intervals and he didn't do much in it. By 5 months old he was sitting up unassisted and LOVED it.
