“My 7 nearly 8 yr old daughter loves this and uses it a lot. We don't have room to have it up in our house, so we keep in our garage and bring out to the backyard when my daughter uses it (keep it out all day and bring in before dark). It's really easy to put together- just 4 big screws. We have added some sand bags as my daughter is doing some big moves on the bar. But it's super stable and if your kid is just doing hip circles- you dont need to add sand bags. I would highly recommend getting the bundle as you really do need the mat and under it as it fits perfectly. We have it set up on a patio- so we feel much safer and she's more confident with the big cushy mat under her. This is really an investment as it's pricey. But it's very stable and compared to other bars out there- this one will last and will not be junk in a year. My son who's 11 can also use it. I would say this could be used at least until my daughter is 11/12...It's been worth it for us as all my daughter wants to do is go on her bar (it's her fav at gym). She really uses it- so it's been worth the investment.”
