OnStage KB5503B Description

The OnStage KB5503B provides adjustable seating for acoustic grand and baby-grand pianos, electric keyboards, and synthesizers. Its 25-inch-long seat features a 3-inch-thick dense foam cushion designed to evenly distribute weight and provide supportive comfort during performances, lessons, and extended practice sessions.

The bench adjusts from 17.5 to 23.5 inches with continuously selectable height settings, allowing musicians to fine-tune their seating position to suit different instruments, playing styles, and posture preferences. A pneumatically assisted mechanism raises the seat when either of the two easy-to-reach levers is pulled, while pulling a lever when seated allows the bench to lower gradually.

Strong, thick metal legs and a horizontal crossbar provide balance and support for users weighing up to 330 pounds. Nonslip rubber feet help keep the bench securely positioned on smooth floors during use.

The black leatherette cushion covering can be wiped clean with a damp cloth for easy maintenance, while the glossy black finish provides a polished appearance for stages, studios, schools, theaters, houses of worship, event spaces, and streaming setups.
