We have ordered the stand for a Yamaha NP-11. This weighs in at just 5 kg, so no extreme stability is required. The enclosed screws to perfectly fit the pockets on the underside, the stand seems like specially made for the keyboard. A real piano is certainly more stable (with 300 kg of weight ...), but the combination has no tilt or shake trend and can be easily carry or move anyway. Suitable especially if you want to stay at home ever built the instrument; for mobile use another model (collapsible) would be more practical. Top in this situation anyway highly recommended, value.
