Overall a great concept. To enable exercise butredt as required is extremely beneficial. The only difficulties we have encountered is that it is more heavy than the regular bariatric transport chair we have owned in the past and when converting from the Rollator to a transport chair, the chair handle height is low for the person pushing. the chair is easily modified between two options but there’s no armrest for the person sitting in the chair so her arms get tired. but overall, I’d buy it again
