Steinway Model O piano cover, measuring 5'10-1/2". Please note that Steinway makes two piano covers that measure 5'10.5"--the model L and the Model O. The model O has a round tail, the model L has square tail. You can tell the model of your Steinway by looking inside your piano. Somewhere, likely on the cast iron plate near the tuning pins, you will see a painted letter with the model of your piano. The cover is made out of a black padded, quilted material--with the outer layer being made of nylon, in a 4" diamond pattern. The inner layer is a soft material to prevent any damage to your piano. Our piano covers feature side splits, which allow you to flip open the front of the piano cover to expose the keyboard, so that you can play the piano without having to take the entire piano cover off. Each split is located above the front leg on each side of the piano. Quilted covers are regarded as the most attractive covers, and this piano cover is suitable for any home setting, as well as churches, schools, or anywhere you want to protect your piano from dust or physical damage.
