Don't think for another second. . . .
Don't think for another second. . . . just buy this for your kids. They will love you for it, you will love yourself for it, and your house will love you too haha! My 5 year old has been using this for a few weeks and when he first started he could not swing all the way across and now he can! The strength he has gained through using this daily is so impressive. We have it in our living room so they are using it constantly - they even hang on it while watching a movie etc LOL.
