Product Overview:

ThevoSiiS Therapy Chair is a seat with integrated impulse sensors that address limited sensory and motor abilities made worse by prolonged sitting in typical classrooms chairs. The pediatric therapeutic chair addresses these limitations with a seat that allows the child to find their body center, gives them sensory input or reminders, and initiates active, upright posture. The very firm seat block provides maximum sensory input, while its long shape encourages the child to use their arms to stabilize themselves. When they do this, they make a change in their spine, establishing a more stable, symmetrical posture.

More Information

The slope seat surface at the rear end of the seat block slightly tilts the pelvis, helping the spine to straighten. ThevoSiiS Therapy Chair supports this active position with a firm support at the lumbar curve, helping the child sit with more stability and confidence. The height of the seat can be adjusted so the legs are correctly positioned, with the feat in firm plantar flexion to support the upright posture. The child can still propel the feet to move ThevoSiiS Therapy Chair independently.The user can operate the break lever and height adjustment independently, giving them a certain degree of confidence. The impulse sensors on the lumbar support are simple to adjust, so the child is getting cues and reminders about the position of their back and help them to find and access the center of their body.

The ThevoSiiS Therapy Chair's firm iliac crest support offers little contact surface to promote active seating and holding. Impulse generators assist orientation to aid the strengthening and centering process. The seat block provides abduction of legs, while floor contact initiates straightening with body axis. The elongated shape aides forward facilitation of the arms for a physiological seating position, while the sloped back slightly tilts the pelvis. Point-shaped impulse transmitters provide orientation to stimulate an erect posture. Therapists have seen improved hand-hand and eye-hand-coordination with increased alertness and significantly more involvement with the environment. The upright sitting posture can strengthen self-esteem, awareness and independence for users. The base frame is fully adjustable with lever brakes, and tilt resistance. Users can easily adjust the height of the chair. A pushbar on the back of the chair allows for pushing it room to room.
