Eison Piano Caster Cups for Upright Piano Wooden Piano Caster with Non-Slip & Anti-Noise Foam Hardwood Floor Protectors, Set of 4, Black

It had good sturdiness. I satisfied.

We purchased these to put under our large upright piano when we put in new hard surface floors. They are sturdy, look nice and give our floor the protection they need from the piano casters. We liked them so well we decided to purchase more to put under our loveseat and chair to keep them from sliding on the new hard surface floor. I originally found these online from another site but the price and shipping was outrageous. This is a great product for a great price and I highly recommend.

These were bought to protect my wood floors from dents and to make it easier to move. They are fantasti! Easy to place. Evenly distributed the weight of the piano and no marks. Highly recommend

Solid products and thick foam on the bottom to protect hardwood floors. Note that the pedals would be positioned higher due to the thickness of the material.

Just put down real hardwood floors and did not want piano making marks on floors. Raised piano up enough to clean underneath and they look good.
