Benefits of the Hi-Low Chair MPS Seating System by Special Tomato

The Special Tomato cushion technology is cool to the touch, and provides a non-sticky surface for your child. The interior foam of each cushion is designed to conform to your child’s body and support them for hours of comfortable sitting. The Special Tomato Hi-Low MPS Seating System includes the Hip-Flex® feature found on all MPS models that allows a 30 degree range of pelvic tilt. This unique positioning feature allows for upright sitting to become more functional and comfortable.

The forward tilt and height adjustability of the Hi-Low Chair MPS Seating System by Special Tomato allows a caregiver to position the user so that they are forward weight bearing, either on the footrest or on the floor. This position helps the user develop muscles within their legs while promoting bone growth and blood circulation. With the same type of positioning with feet on the floor, a caregiver can also work on sit to stand transfers with the user. By giving a forward tilt and elevating the user so that their legs are positioned half-way to a vertical position, the user can achieve success with a sit to stand transfer quicker. As the user becomes proficient, the caregiver can lower the starting point to increase the challenge.
