Rifton Laterals for Activity Chairs - Necessary for clients who need good upper body support, lateral supports are important for proper alignment of the spine. Laterals help position your client correctly and securely and are independently adjustable vertically and horizontally. Lateral supports can be purchased with or without a chest strap attached. With the addition of a wide chest strap to the laterals, clients without upper torso control gain added trunk support and security to help correct alignment of the spine.
