Products to help 10mos old baby to stand safely?

My boy is 10 months old and able to pull to stand, sit, and almost able to get from lying to sitting. I'm worried I'm holding him back though. The only times he gets to really stand is in his bouncer, when I'm sitting with him on floor and he tries to pull up on me, and if on the couch and I let him hold on the back of it. He doesn't have the full balance to stay standing on his own without a little help. I'm worried its because he doesn't have much of an opportunity to do it on his own.

What products are good for this?
