Product Details

Reinforcement Board for Grand Piano Floors (Insulation & Soundproofing Type)
────────────────────────────────────────
This was used as shown in the attached photos.
Therefore, there are circular marks from the casters on the surface, but they are not visible when the piano is placed on it. I personally believe it is in very good condition, but please refrain from purchasing if you are concerned.

* Purchase Location: Musical Instrument Store
* Material: MDF + White Q-on
* Size: Diameter: Approx. 40cm, Thickness: Approx. 2.2cm
* Weight: Approx. 1.2kg per board
* Surface Finish: Black, Mirror Finish Paint
* Back Finish: White Q-on
* Contents: Set of 3 boards (for one piano)

A grand piano weighs approximately 300kg.
Since approximately 100kg of load is applied to each leg,
this product is used to distribute the weight over a wider area to prevent floor sagging and caster dents in your home.

Additionally, it is not ideal for heat from underfloor heating to transfer to the piano. By placing this insulating type board under the casters, it prevents negative effects on the piano.

This is a device used in conjunction with casters, so I have included casters in the set.

Casters: Approximately 1500 yen each.

These are also for grand pianos. Purchased in 2023.

Please refer to the sixth photo. While the reinforcement board has caster marks, the floor where the grand piano was placed (tatami) showed no marks at all.

If you are placing a grand piano on tatami or underfloor heating flooring, you should definitely use this. It also prevents slipping during earthquakes.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
