The contoured, smooth, molded plastic seat is designed to support your child in a natural position for toileting. The seat simply slides under the adapter and is lowered into place when needed. The standard toilet bowl adapter connects under the seat so as not to interfere with the seat when the toilet support is not in use. Comes with an anterior trunk support featuring a channeled forearm guide and contoured handgrip to promote a successful position for elimination. Adjustable knee loops position and stabilize the knees in flexion while the bi-level footrest positions and supports the lower legs. The foot support can also be used as a step stool for washing up afterwards! A soft deflector does not interfere with transfers yet it successfully directs urine into the bowl. All components are completely washable with soap and water.
