Query: You'll never enjoy playing.

When I bought YAMAHA P95 digital piano, I also bought this piano stand as the bundle.Assembling was very easy. I quickly set up and played.BUT,1. Piano never be flat!I think it's a structural problem.&#12288;It's always droopy posture. We never realize when we look but when we play, it's so uncomfortable.If you play on the stage with standing, it's OK. X structure allow us to bring everywhere. But I can't recommend if you want to play the piano, sitting on the chair.2. Piano is bouncing!When I play the piano, piano shakes, not right and left but up and down according to my motion.I was so uncomfortable.I think these problems are not due to this product. X structure is the problem. Please be careful to other x structure piano stand.I'm going to buy YAMAHA P85.
