Question: is it expandable?
Document: What a great piece. My husband put it together in about ten minutes the night before my seven year old's birthday. He said it was very easy. It required a socket wrench, open end wrench and phillips screw driver. Nothing more. The birthday girl saw it in the morning when we uncovered it and loved it. She's basically been on and off of it for about the last ten hours!
This well made, easy to assemble practice bar is perfect for my new gymnast. Sturdy and well-made. Fast delivery. Highly recommend!
Okay product but no contact from Nimble Sports. Evidently they are a small company and they can't keep up with the hoilday orders. I've been waiting over 3 weeks for my bar and mat and now they have a pre-recorded phone message which tells me a lot of customers are calling to complain!!!! !
My 4 year old daughter started gymnastics and really loves it, so I thought I would buy some equipment for her to practice at home. Looked at other bars, but this one seemed the best for the price. It is quite sturdy and can even hold up my 10 year old son who is almost 80 lbs. It included the matt which fits perfectly. The assembly was quite easy as long as you have 2 adjustable wrenches and a power screwdriver. I am very pleased and my daughter is thoroughly enjoying it.
It comes with a mat and its thick. You can put chalk on the wooden bar and it feels great. I would give it five stars if it were adjustable. Perfect for someone about 48" , my daughter's friend is 59" and she was comfortable. I would say about up to 5 feet tall. It is of solid construction  and it moves slightly with a back circle. Overall, nice product. I hope this review helps.
Great bar! Purchased for my 7 year old. Can't keep her off of it! Built sturdy and works perfect for her.
