This optional Trunk Harness is designed for exclusive use with the Pango Pediatric Activity Chairs. The Harness provides further positioning support for the chair, keeping the child safely and securely in place, limiting the movement of their torso. The secure 4-point latch system is terrific for overly active children who may rock in place, preventing injuries to children by keeping them upright. Please note, this is a Small Trunk Harness for the Pediatric Activity Chair only. The Pango Pediatric Activity Chair is available separately. The Pango is CE marked and meets the essential requirements of all relevant European Medical Device Directives. No assembly required. Open the box and simply attach the Harness to the chair. This Harness fits the Small sized Pango Activity Chair only. If you have the Medium chair, Medium Stabilizers are available separately. The Harness works in conjunction with the included pelvic belt and does not restrict any of the chair's adjustable features. To clean, wash with a damp cloth and mild detergent.
