Grandpianocarpet model Steinway is handmade in the shape of your Steinway grand piano and extended by 60 cm so that your Piano Bench rests on the Grandpianocarpet model Steinway Extended.
A Pianocarpet is not a normal carpet but is equipped with our heat shield. Placing only this heat shield under your instrument does not look nice and therefore we use a carpet to incorporate our heat shield.
A Pianocarpet protects the case and the soundboard of the grand piano as well as the keybed and the legs against direct rising warm air from your underfloor heating. Rising warm air extracts moisture from your grand piano with the consequence that the structural gluing dries out and lets loose. The solution: Place a Pianocarpet underneath your grand piano!
When the relative humidity in the surroundings of your grand piano is too low, use a Pianocarpet in combination with a damping system.
Additional information; What relative humidity is good for your piano? When the pointer of the hygrometer is between 45-60%. Is the pointer lower than 45% the relative humidity is too low and a damping system can be the solution.

You can place your Grandpiano directly on the carpet without using casters cups. Therefore, casters cups are not included when ordering a Pianocarpet. If you like to place your grand piano on casters cups it is possible and you can order the cups at extra costs.
It is possible that the Pianocarpet has a deviation from the stated size of max 2%
