Booster cushions are a great way to add to your bench in a situation where the pianist needs a little more height. All of our booster cushions are 14" x 14" and are 2-1/2" thick and can be placed on top of an existing piano bench cushion for more height. These booster cushions are a good solution for piano teachers who have young students who have trouble being at the correct height for good posture. Available in a variety of different colors and fabrics. The style of our booster cushions are the same style as our custom piano bench cushions which is a single welt bullnose style cushion. No ties or straps are included with these.
