We got this for Christmas, our daughter was 6 months then, she couldn’t touch the floor at the time so we just used a pillow and that worked just fine. She is on the smaller size but grew into it great. We removed the pillow about a month later. 
In our experience, we never had the same issues as others. No issues with the teddy bear flinging In her face, the challenge of trying to reach the toys were good for her (she can reach them now). And it’s super easy to clean and was easy to set up. We love the look of it in our house and love that it’s not too big and overbearing with toys. she is almost ten months now and still loves it.
