Here is a high quality toilet riser or commode with LOCKING WHEELS. This is a very solid and safe unit. If you are recovering for surgery, or know a senior that needs stability on the throne, this is what you need. The extra height and support arms are a godsend for anyone in need of a safer bathroom. Don't buy a cheap white plastic toilet riser....most are dangerous and most don't attach properly! Safety first. See our other ad for a high quality shower chair. Located near UVIC. Great for recovery such as hip surgery casts operation mobility issues grab bar toilet riser toilet height bathroom safety
