Comfort and safety yeah!
Like the chair but still a little skittish because previously purchased a chair at local store that was not bariatric and its legs were bending after a few uses.  This chair at first appears similar but it has an x braced to stabilize legs.  This seems to work out that issue.  Also big plus is the height adjusters on legs are not push button in types but instead clamp with buttons attached comes out to adjust height then you just push back in.  Much easier to use.  Received even faster that expected.  Thanks Invacare!
