- Why can't there be dental chair that is more kids-friendly?
Based on extensive pediatric dentistry research, we set out to create a unit that protects children from hazards caused by unexpected movements.
■Support a child’s “I can do it.”

With a minimum seat height of just 430 mm, even small children can get on and off the chair by themselves. With the optional step, even smaller children can do so with ease. The dentist’s area and the patient’s area are clearly separated, reducing the risk of children touching instruments.

The spittoon is positioned close to the chair and is movable, making it easier for children to rinse. The spittoon bowl features playful graphics to make rinsing more fun.

Communication support options, such as “Open your mouth wide like this tiger!” (Smile Support Animal), help engage children during treatment.
■Versatile treatment styles

Ample space around the chair is ensured by the cart-type table and a wide-range, movable assistant’s holder. Flexible support for two-handed or four-handed dentistry, with or without parental supervision.
■Safety and peace of mind for everyone

A child-sized seat means there’s no need to pull or lift the child into position before treatment. The adjustable headrest accommodates a wide range of ages for comfortable care.

The full-flat, one-piece seat has no gap between the backrest and cushion, preventing debris from entering and making cleaning easier.

The full-flat, one-piece design also minimizes pinch points. In the unlikely event of pinching, a safety mechanism reverses motion to release it.
