This is a Tub Stand designed to be use with the Otter Pediatric Bath Chairs. The stand allows the bath chairs to be attached easily and securely through quick-release locks. The sturdy aluminum stand sits on top of 4 swivel casters, making this unit ideal for roll-in showers. The casters lock too, making the stand and chair immobile in the shower. With the stand attached, it's a snap to position and reposition the chair as needed. At 21" tall, the stand raises chairs to the standing height of most caregivers, meaning no more bending and no more achy backs. Minor assembly is required for the Shower Stand, needing only a screwdriver. This Shower Stand fits the Small, Medium and Large Otter Pediatric Bath Chairs. Please note, this is the Shower Stand only. Otter Bath Chairs are available separately. A child should never be left unattended while the bath chair is in use. With a weight capacity of 200 lbs., the Shower Stand will be suitable for most children. Using the stand does not interfere with any of the adjustability of the Bath Chair. Incredibly user friendly as all the adjustments are tool-free and the stand folds flat when not in use for easy storage. Easy to clean needing just warm water and soap.
