Finding the best chair for someone with Dementia will depend on the type they have got, and also the stage of the condition they are at.  However, finding an adjustable care chair with easy movement and recline/tilt-in-space functionalities, and supportive accessories and cushions, will ensure that the individual comfort, postural and pressure care needs of your patient are met.  Something like the Lento Mobile or Lento Care Chair can be a great option for someone in the early stages of Dementia, with higher levels of mobility.  The Lento Neuro is an amazingly comfortable "cocooning" care chair for people in the later stages of the condition, and who are likely to be sat in their chair for a longer period of time.
