1. Comfort and space: The piano stool for two people is more spacious, which can provide enough seating space for two people. This is very useful for piano teachers and students, piano accompaniment and so on. The double piano bench can also provide better comfort and support, so that players will not feel tired when sitting on it for a long time. The lifting piano stool has a small space and can only accommodate the next person, so the comfort is weak.

2. Stable and durable: the piano stool for two people is usually made of solid material, which has better stability and durability. This is very important for long-term use and regular exercise. The lifting piano bench may be more flexible in height adjustment, but it may not be as stable and durable as the double piano bench.
