I bought this chair in June for my dad for Father's Day and by August it began falling apart.  The cylinder to raise or lower the chair broke and yesterday when I was up there he almost fell out of it when he tried to get up because the bottom part of the seat is falling apart.  Unfortunately I did not buy the offered additional warranty because I had bought the exact chair for myself in December and it is fine.  The chair is still under the company's 90 day warranty so hopefully they will honor it.  If not I might as well have thrown $403 dollars in the trash.  Extremely disappointed in the quality of this chair!!!
