With a comfortable, inviting feel and a moderate range of motion, Virco's ZUMA^® rockers work in a variety of learning environments where students would benefit from a rocking chair.

Model ZROCK18 has a 17-5/8 seat height, making it a great choice for high school settings and larger middle school students.

For elementary and middle schools, models ZROCK15 (14-5/8 seat height) and

ZROCK13 (12-3/4 seat height) let younger, smaller students experience the fun that comes with a ZUMA rocker. Guaranteed to brighten the mood of any environment: ZUMA^®rocks!

The ergonomically contoured ZUMA^® shell has the following features and benefits:

• a smooth rocking motion that allows access to a calming and organizing sensory experience
• a "rocker brake" that controls the extent to which the chair can tip backwards
• a continuous rocker bar that eliminates distracting noise from traditional four legged chairs that scrape against the floor
• a range of pleasing and calming colors to make seating environment more appealing and engaging
• a gentle lumbar (lower back) swell in the chair shell that promotes lordosis (proper spinal curvature) and comfortably supports an upright posture;
• a deeply relieved seat that helps reduce pressure on sensitive ischial tuberosities (bottom bones);
• a hollowed-out wallet area where the seat and back meet, that prevents uncomfortable pressure on the sacrum and coccyx (tailbones);
• a blending of deeply sculpted contours toward the centerline of the seat, allowing users to settle into the shell for excellent comfort and posture;
• a gradually relieved thigh area that gently supports upper legs without restricting movement or circulation;
• a smoothly rolled crest at the top of the backrest that minimizes edge pressure on the user's upper back - even for taller people in relaxed postures - providing better comfort, circulation and freedom of movement; and
• a comfortable waterfall front edge that promotes good circulation through the popliteal arches (behind the knees) to the lower legs and feet.
