Dementia and Alzheimer's Disease are progressive conditions, so we recommend that you have regular assessments with your Occupational Therapist, and make changes to the settings and configuration of your chair based on their suggestions and the users changing needs.  Every individual has different care needs, and progresses at a different rate, so it’s important that the chair you buy is one that can be easily adjusted to suit this.  Modular and adaptive seating solutions such as the Lento Care Chair are great for this.
