For people with limited movement in their hips or knees, the Angled version Etac Hi Loo with Arm Supports is an ideal aid to personal independence.The forward tilt makes it much easier to sit and stand making it suitable for users with restricted knee or hip mobility, whilst the sturdy arm supports provide valuable support and security. The angled Etac Hi Loo is similar in all other respects to the other Hi Loo models and the arm supports feature the same folding action that is so useful during transfers or in bathrooms with limited space. Cleaning is easily achieved as the whole unit will simply detach from the toilet.
